Magic Quadrant for Security Information and
Event Management
25 June 2014 ID:G00261641
Analyst(s): Kelly M. Kavanagh, Mark Nicolett, Oliver Rochford
VIEW SUMMARY
Broad adoption of SIEM technology is being driven by the need to detect threats and breaches, as well as
by compliance needs. Early breach discovery requires effective user activity, data access and application
activity monitoring. Vendors are improving threat intelligence and security analytics.
Market Definition/Description
This document was revised on 1 July 2014. The document you are viewing is the corrected
version. For more information, see the Corrections page on gartner.com.
The security information and event management (SIEM) market is defined by the customer's need to
analyze security event data in real time for internal and external threat management, and to collect,
store, analyze and report on log data for incident response, forensics and regulatory compliance. The
vendors included in our Magic Quadrant analysis have technologies that have been designed for this
purpose, and they actively market and sell these technologies to the security buying center.
SIEM technology aggregates event data produced by security devices, network infrastructures, systems
and applications. The primary data source is log data, but SIEM technology can also process other forms
of data, such as NetFlow and packet capture. Event data is combined with contextual information about
users, assets, threats and vulnerabilities. The data is normalized, so that events, data and contextual
information from disparate sources can be correlated and analyzed for specific purposes, such as network
security event monitoring, user activity monitoring and compliance reporting. The technology provides
realtime security monitoring, historical analysis and other support for incident investigation and
compliance reporting.

Vendor Strengths and Cautions
AccelOps
AccelOps is one of the few vendors that have capabilities that are directed at both IT security and IT
operations. AccelOps provides log management, search, alerting, realtime correlation, and a dashboard
environment for unified security, availability, and performance monitoring and analytics. The vendor's
primary focus is its SIEM solution for security practitioners and managed security service providers
(MSSPs), but AccelOps also provides a tightly integrated performance and availability monitoring (PAM)
solution that is oriented to the IT operations area. MSSP customers typically use both the SIEM and PAM
capabilities in order to provide a broad monitoring service to their customers. For enduser customers, the
focus in most cases is SIEM, but about 25% of enduser customers have added the PAM component.
Over the past 18 months, the vendor has experienced rapid growth from a relatively small installed base,
and is becoming increasingly visible on SIEM evaluation shortlists. Over the past 12 months, AccelOps
updates have included integration for dynamically updated external threat intelligence feeds and support
for statistical anomaly detection. Development plans include advanced and cloudbased threat
visualization analytics.
AccelOps is a good fit for enterprises and MSSPs that require a combination of security monitoring and
PAM, and integrated configuration management database (CMDB) capability.
Strengths
AccelOps' combination of SIEM and PAM capabilities can be used to implement unified security and
operations monitoring from logbased event sources, and can provide the security organization with
additional operations support for a securityfocused deployment.
AccelOps provides strong support for deployment in a virtualized environment as well as public,
private and hybrid clouds.
Customers report that the technology is relatively easy to deploy, especially given the support for
both security and operations monitoring.
Cautions
Reporting capabilities are very flexible, but some users indicate that easeofuse improvements in
report customization are needed.
The AccelOps design places a heavy reliance on highquality CMDB data in order to accurately place
each device into an asset category. Organizations must validate the accuracy of the automated
discovery and classification activities.
While AccelOps provide a UI for the simpler integration of unsupported data sources, outofthebox
advertising, customer programs and positioning
statements.
Sales Strategy: The strategy for selling products that
uses the appropriate network of direct and indirect
sales, marketing, service, and communication
affiliates that extend the scope and depth of market
reach, skills, expertise, technologies, services and the
customer base.
Offering (Product) Strategy: The vendor's approach
to product development and delivery that emphasizes
differentiation, functionality, methodology and feature
sets as they map to current and future requirements.
Business Model: The soundness and logic of the
vendor's underlying business proposition.
Vertical/Industry Strategy: The vendor's strategy
to direct resources, skills and offerings to meet the
specific needs of individual market segments, including
vertical markets.
Innovation: Direct, related, complementary and
synergistic layouts of resources, expertise or capital
for investment, consolidation, defensive or pre
emptive purposes.
Geographic Strategy: The vendor's strategy to direct
resources, skills and offerings to meet the specific
needs of geographies outside the "home" or native
geography, either directly or through partners,
channels and subsidiaries as appropriate for that
geography and market.

support for thirdparty applications is limited.
IAM integration is limited to Microsoft Active Directory and Lightweight Directory Access Protocol
(LDAP).

AlienVault
The foundation of AlienVault's security management solution is Open Source SIEM (OSSIM), which
provides SIEM, vulnerability assessment, NetFlow, network and host intrusion detection, and file integrity
monitoring. AlienVault offers SIEM in two products, one open source and one commercial. AlienVault sells
and supports Unified Security Management (USM) as software or appliance, and USM extends OSSIM with
scaling enhancements, log management, consolidated administration and reporting, and multitenanting
for MSSPs. The sensor, logger and server components of USM are available as allinone or separate
servers in several tiers to match the size of customer environments. The vendor's target market is
enterprises with smaller security staffs and limited security programs that need multiple integrated
security technologies at a lower cost and with greater simplicity. AlienVault's Open Threat Exchange
community enables sharing of Internet Protocol (IP) and URL reputation information. AlienVault Labs
provides an integrated threat intelligence feed to its commercial products that includes updates to
signature, vulnerability, correlation, reporting and incident response content. AlienVault has added several
wizard and dashboard features to support easier deployment, configuration and maintenance of network
and hostbased sensors and controls. AlienVault's USM platform provides centralized configuration and
management of all AlienVault components.
The AlienVault USM platform should be considered by organizations that need a broad set of integrated
security capabilities at relatively low cost compared with other commercial offerings, and by organizations
that want a commercially supported product that is based on open source.
Strengths
AlienVault USM provides integrated capabilities for SIEM, file integrity monitoring, vulnerability
assessment, NetFlow and both hostbased and networkbased intrusion detection systems.
Customer references indicate that the software and appliance offerings are much less expensive
than corresponding product sets from most competitors in the SIEM space.
Cautions
Although AlienVault has recently expanded the number of predefined correlation rules for thirdparty
commercial products, some existing customers identify this as an area that needs further
improvement.
Identity and access management (IAM) integration is limited to Active Directory and LDAP
monitoring, and application integration is primarily with opensource applications.
AlienVault's workflow capabilities do not include integrations with external directories for workflow
assignments.
Return to Top
BlackStratus
BlackStratus has two offerings, Log Storm and SIEM Storm. Log Storm provides log management
capabilities aimed at MSSPs and small to midsize enterprises, and is available as virtual and hardware
appliances. SIEM Storm provides features such as multitenancy and security event management (SEM)
capabilities, such as analytics, historical correlation and threat intelligence integration, and is deployable
as software or virtual images. SIEM Storm can be deployed in combination with Log Storm, utilizing it as
the storage and collection tier, or it can be deployed standalone with an HP Vertica Analytics Database
back end.
Log Storm and SIEM Storm provide an integrated incident management and ticketing system guided by
the SANS sevenstep incident remediation process, and SIEM Storm also allows the tracking of SLA
metrics to accommodate MSSP and servicecentric environments. A Web services API providing twoway
integrations with thirdparty systems offers powerful integrative capabilities, but outofthebox support
for thirdparty data sources is limited compared with competitor offerings.
In the past 12 months, BlackStratus added a cobranded portal, integrations with FireEye, Mandiant and
EMC's RSA NetWitness, and support for the Vertica Analytics Database to be used as the back end for
SIEM Storm.
BlackStratus is a good fit for service providers requiring a customizable SIEM platform, and enduser
organizations looking tor wellformed multitenancy support.
Strengths
Log Storm and SIEM Storm provide a twoway integration API to enable custombuilt service
architectures.
Both offerings include a fully integrated incident and ticket management system based on the SANS
sevenstep remediation process.
SIEM Storm can be deployed with a Vertica Analytics Database back end.
Cautions
Outofthebox support for thirdparty data sources is limited and requires custom scripting.
BlackStratus has few technology integration partnerships or deep thirdparty integrations.

Advanced security capabilities such as commercial threat intelligence feeds, network forensic/deep
packet inspection (DPI) and identity and access management (IAM) integrations are not supported.
BlackStratus has focused on sales to security service providers, and has not been very visible in
competitive evaluations for enduser deployments.
Return to Top
EMC (RSA)
RSA, The Security Division of EMC (including enVision, NetWitness and Security Analytics), has a large
SIEM installed base. However, during 2013, RSA completed its transition from enVision and NetWitness
to the Security Analytics platform as Gartner customers continued to identify RSA enVision as the most
frequently displaced SIEM technology, RSA Security Analytics (based on the NetWitness platform)
provides log and full packet data capture, security monitoring forensic investigation, and analytics. RSA
will support the enVision platform until the end of 2017. The Security Analytics reporting system can pull
data from both the Security Analytics data structures and the Internet Protocol Database (IPDB) in
enVision, helping to accommodate the transition from enVision to Security Analytics within the RSA
installed base. The Security Analytics Archiver provides longterm storage and access for compressed logs
and log metadata. Security Analytics Warehouse provided big data analytics. The initial release of Security
Analytics had limitations on analytics (keyword search into raw data), but a 2013 release provided an
analytics engine as an integral component of the Security Analytics Warehouse.
The initial release of Security Analytics lacked complex correlation rule support and a customization
interface. RSA has released the Event Stream Analysis appliance, which provides realtime alerting for
logs and packets, and includes a rule customization interface. In 2013, RSA released the Security
Analytics AllinOne appliance that is a packaging option for smaller deployments. Nearterm development
plans include native incident management and more behavioral profiling capabilities related to outbound
connections.
RSA Security Analytics should be considered by organizations with highsecurity environments and the
staffing resources to support a complex technology that requires extensive customization, and that have
a need for a combination of both logbased monitoring and networklevel monitoring for threat detection
and investigation.
Strengths
RSA's Security Analytics platform offers a combination of analytics and basic event monitoring for
both full packet capture and log data.
RSA Security Analytics can be deployed by organizations that have implemented another vendor's
SIEM in cases where full packet capture capabilities are needed
Cautions
Security Analytics' support for complex correlation is very recent, and it has very little production
experience in this area.
Security Analytics displays are basic. The user interface lacks predefined dashboard views and
requires extensive customization.
Return to Top
EventTracker
EventTracker targets its SIEM software and service offering primarily at midsize commercial enterprises
and government organizations with security and operations event management and compliance reporting
requirements. The EventTracker agent provides support for file integrity monitoring and USB control.
Basic profiling capabilities are provided via a behavior module that can establish a baseline of a user
configurable period of time and can issue alerts on deviations from normal. During 2013, the vendor
expanded its SIEM Simplified remote monitoring service (incident log and configuration review, incident
investigation, and audit assistance) through an integration with OpenVAS vulnerability assessment
scanning and Snort intrusion detection. EventTracker also introduced basic incident response workflow
support. Development plans include support for monitoring packaged applications that are prevalent in
midsize enterprises and a SaaS offering hosted in Amazon Web Services, which will be directed to
managed service provider (MSP) partners. EventTracker is suited for midsize businesses that require log
management, SEM, compliance reporting and operations monitoring via a softwarebased solution, and
midsize businesses that have a requirement for onpremises or cloudhosted SIEM in combination with
basic monitoring services
Strengths
EventTracker is easy to deploy and maintain, with compliance and usecasespecific knowledge
packs that provide prebuilt alerts, correlation rules and reports.
EventTracker supports centralized agent deployment and management in Windows environments.
EventTracker includes a behavior analysis module that provides profiling and anomaly detection
functions.
Services such as periodic log review, audit assistance and health check are available from the vendor
at a low cost.
Cautions
The vendor targets the midmarket, but is not as visible on customer shortlists as other SIEM
vendors that are also targeting this segment.

EventTracker's capabilities for application monitoring are more limited than other SIEM products
targeting enterprise deployments, as it lacks integration with major packaged applications.
The embedded incident ticketing capability is limited in the area of response workflow.
Return to Top
HP
HP's ArcSight line of SIEM solutions resides within HP's Enterprise Security Products (ESP) business unit,
which also includes HP TippingPoint and HP Fortify. ArcSight Enterprise Security Manager (ESM) software
is oriented to largescale, SEMfocused deployments. ArcSight Express is an appliancebased offering for
ESM that is designed for the midmarket with preconfigured monitoring and reporting. ArcSight Logger
appliances and software provide log data collection and management functions that can be implemented
standalone or in combination with ESM.
During 2013, ArcSight remained among the most visible SIEM competitors on Gartner client shortlists,
but the introduction of competitive SIEM technologies within large ArcSight accounts continued, with
customers citing ESM complexity and cost as inhibitors to expansion. With ArcSight ESM version 6, HP
replaced the ESM Oracle Database with the Correlation Optimized Retention and Retrieval Engine (CORR
Engine) and implemented a simplified events per second (EPS)based pricing model. We have validated
significant improvements in eventhandling capacity on the same hardware with reference customers. In
late 2013, HP introduced ArcSight Risk Insight for ESM, which provides risk rating and management
dashboards for security event data. HP also introduced ArcSight Application View, which enables
application activity monitoring that is not dependent on log data. HP also released enhancements to
ArcSight Express to simplify deployment and customization. Development plans include further
integrations with HP's Vertica Analytics Platform and additional improvements in ease of deployment.
ArcSight Express should be considered for midsize SIEM deployments. ESM is appropriate for larger
deployments, as long as sufficient inhouse support resources are available.
Strengths
ESM provides a complete set of SEM capabilities that can be used to support a security operations
center.
ArcSight Express provides a simplified option for midsize SIEM deployments.
ArcSight Logger can provide an inexpensive log management capability for twotier deployment
architectures that require longterm event archiving.
Optional modules provide advanced support for user activity monitoring, IAM integration and fraud
management.
ArcSight continues to be very visible in competitive evaluations of SIEM technologies.
Cautions
ArcSight provides realtime statistical correlation, but profiling and anomaly detection operate
against historical data only.
While the CORREngine has eliminated a major source of deployment and support complexity,
customers will still find ESM to be more complex than other leading solutions.
Return to Top
IBM Security
IBM Security's QRadar SIEM technology provides log management, event management, reporting and
behavioral analysis for networks and applications. QRadar can be deployed as appliance or software
(running on Red Hat Enterprise Linux Server appliances) in an allinone solution for smaller
environments, or it can be horizontally scaled in larger environments using specialized event collection,
processing and console appliances. A distinguishing characteristic of the technology is the collection and
processing of NetFlow data, DPI, full packet capture, and behavior analysis for all supported event
sources.
Enhancements to QRadar during the past 12 months included the introduction of QRadar Incident
Forensics, which extends flow analysis, adding DPI and full packet capture capabilities. In addition, IBM
Security introduced integrated vulnerability scanning via QRadar Vulnerability Manager (using technology
licensed from Critical Watch), as well as new graphing/charting capabilities, improved search performance
and API enhancements. IBM has developed twoway integration between QRadar and IBM's InfoSphere
BigInsights, and also with IBM's analytics and data visualization technologies. IBM also provides additional
connectors to Hadoop instances.
IBM offers a comanaged service option for QRadar, which combines an onpremises QRadar deployment
with remote monitoring from IBM's managed security services operations centers. QRadar is a good fit for
midsize and large enterprises that need general SIEM capabilities, and also for use cases that require
behavior analysis, NetFlow analysis and full packet capture.
Strengths
QRadar provides an integrated view of the threat environment using NetFlow DPI and full packet
capture in combination with log data, configuration data and vulnerability data from monitored
sources.
Customer feedback indicates that the technology is relatively straightforward to deploy and maintain
in both modest and large environments.
QRadar provides behavior analysis capabilities for NetFlow and log events.

Cautions
QRadar provides lessgranular role definitions for workflow assignment compared with competitors'
products.
QRadar's multitenant support requires a master console in combination with distributed QRadar
instances. The number of thirdparty service providers that offer QRadarbased monitoring services
is limited when compared with vendors that lead in this area.
Return to Top
LogRhythm
LogRhythm sells its appliance and softwarebased SIEM solutions to midsize and large enterprises. The
SIEM offering can be deployed in smaller environments with a single appliance or software instance that
provides log management and event management, or it can be scaled as a set of specialized appliances or
software instances (log management, event management and centralized console). Network forensic
capabilities such as DPI flow monitoring and full packet capture are supported via LogRhythm's Network
Monitor, which can be integrated as a network sensor. The technology also includes optional agents for
major OSs that can be used for filtering at the source. LogRhythm's System Monitor Agents include host
activity monitoring capabilities such as system process monitoring and file integrity monitoring for
Windows and Unix.
New features and improvements in the latest 6.2 release of Security Intelligence platform include Active
Directory groupbased authentication for LogRhythm users, System Monitor Agent and collector load
balancing, and a new capability designed to infer missing user information from event data called the
Identity Inference Engine. Other enhancements in the past 12 months include a new UI release in 1Q14
that provides tablet support. Moreover, predefined correlation rules have increased to more than 500, and
predefined modules containing correlation rules, saved searches and reports covering topics such as
privileged user monitoring, network anomaly detection and targeted attack detection have been added.
LogRhythm also released Network Monitor in 2013, a network forensic solution that provides flow
analysis, deep packet inspection and full packet capture capabilities that can be seamlessly integrated
with LogRhythm SIEM as a network sensor.
Plans for the next 12 months include enhancements to case and incident management support, the user
interface, and data storage efficiency.
LogRhythm is an especially good fit for organizations that require a combination of SIEM, file integrity
monitoring (FIM), and network monitoring, and those organizations that value ease of deployment and
predefined function over a "build your own" approach to monitoring.
Strengths
LogRhythm provides a balance of log management, reporting, event management, privilegeduser
and file integrity monitoring, and network forensic capabilities to support security operations and
compliance use cases.
Its appliance format and configuration wizards allow for fast deployment with minimal resources.
Gartner receives consistent user feedback stating that LogRhythm's predefined correlation rules and
reporting templates provide coverage for the most useful and important use cases and ease initial
implementation.
LogRhythm continues to be very visible in competitive SIEM technology evaluations of Gartner
clients.
Cautions
Users report that email alert template content can only be minimally customized.
In order to continue to support older versions of devices, legacy log processing rules are not
removed. Feedback has indicated that this can cause confusion among users.
Return to Top
McAfee
McAfee, part of Intel Security, provides McAfee Enterprise Security Manager (ESM), which combines
security information management (SIM) and SEM functions, and is available as a standalone, allinone,
virtual appliance and delivered as a managed service by partners. Capabilities can be extended and
enhanced with a range of specialized addon products, such as Database Event Monitor (DEM), which
provides database activity monitoring and analysis, Application Data Monitor (ADM) for application
monitoring, and Global Threat Intelligence (GTI). McAfee is further developing integration of ESM with its
wider security portfolio to enable context about vulnerabilities, endpoint state and threats, and to enable
automated response and blocking.
Among the enhancements released in the past 12 months were a new suite of regulatory compliance
reports, the capability to use flow data and statistical anomaly tracking in correlation rules, and big data
connectors for Hadoop integration. Data obtained via the Hadoop connectors can be used to populate
watchlists for correlation and to enrich SIEM data. Plans for the next 12 months include deeper
integrations with McAfee's own portfolio to enable autoresponse capabilities such as policy changes on
enduser devices, the quarantining and blacklisting of malicious activity, a software development kit
(SDK) for external data queries and system management, enhanced threat detection utilizing Data
Exchange Layer and Threat Intelligence Exchange, and additional data obfuscation for enhanced
compliance in privacy laws.

McAfee Enterprise Security Manager is a good choice for organizations that require highperformance
analytics under higheventrate conditions, as well as organizations with advanced requirements for
monitoring database applications and industrial control systems.
Strengths
Some of the highest event ingest rates and query performance levels that we have been able to
validate have been with McAfee Enterprise Security Manager customers.
Database and application monitoring, as well as networkbased packet inspection, are provided for
via McAfee Enterprise Security Database Event Monitor and Application Data Monitor.
McAfee Enterprise Security Manager has strong industrial control system (ICS) and supervisory
control and data acquisition (SCADA) device support.
Cautions
Users have indicated that vendor support is good, but it can be difficult reaching the right point of
contact.
McAfee's advanced SIEM features and capabilities in areas such as endpoint intelligence and
automated response require integrations with, or further investments in, other McAfee portfolio
products.
NetFlow filtering and alerting capabilities are limited. For example, there is no easy way to include all
the packet data from an event that caused an alert in an email notification.
Return to Top
NetIQ
During 2013, NetIQ focused on completing the consolidation of NetIQ Sentinel (acquired from Novell)
with its existing SIEM technology, as well as with its Change Guardian host monitoring. NetIQ's SIEM
offering is based primarily on the Sentinel platform, in combination with agent technology and content
from Security Manager. NetIQ Sentinel is composed of three packages: Sentinel, Sentinel Log Manager
and Change Guardian. Optional host monitoring agents are also available. Sentinel and Change Guardian
are offered both as software and virtual appliance deployments. NetIQ Sentinel integrates with other core
NetIQ technologies (AppManager, Identity Manager, Access Manager, Directory and Resource
Administrator, and Secure Configuration Manager). Enhancements in 2013 included a common
administration interface for Sentinel and Security Manager components, initial support for NetFlow
analysis, initial support for user import of threat intelligence feeds, and visualizations and point
improvements in other areas. Development plans include improvements in scalability, usability and MSSP
support.
Sentinel is a good fit for organizations that require largescale security event processing in highly
distributed environments (such as retail). and is an especially good choice for organizations that have
deployed NetIQ IAM infrastructure and need security monitoring with an identity context.
Strengths
Sentinel and Sentinel Log Manager are appropriate for largescale deployments that are focused on
SEM and threat monitoring.
The Change Guardian product line provides policybased privileged, user activity monitoring and
change detection for Active Directory, Windows, Unix and Linux, as well as file integrity monitoring
for host systems.
NetIQ agent technology can provide guaranteed delivery mechanisms over and above native
platform audit functions or agentless methods for use cases that require user and data access
monitoring for servers.
Cautions
NetIQ Sentinel has relatively low visibility in competitive evaluations of security monitoring
technology.
There are no specific integrations with IP reputation or other external threat intelligence feeds,
although the vendor indicates the intention to release initial support during 2014.
Remote monitoring services for Sentinel are provided by a smaller number of thirdparty service
providers when compared with major competitors.
Sentinel lacks the ability to replay historical event data against current correlation rules for threat
detection use cases.
Return to Top
SolarWinds
SolarWinds packages its Log and Event Manager (LEM) software as a virtual appliance. LEM has
integrations with SolarWinds' other products for operations monitoring to support activities such as
change detection and root cause analysis. SolarWinds' development road map is focused on increasing
ease of deployment and ease of ongoing operations for resourceconstrained security groups. SolarWinds
LEM is a good fit for small or midsize companies that require SIEM technology that is easy to deploy and
those that use other SolarWinds' operations monitoring components.
Strengths
SolarWinds LEM is easy to deploy and provides extensive content in the form of dashboards,
predefined correlation rules and reports.

The technology is also wellsuited for organizations that have already invested in the vendor's other
technology solutions.
An agent for Windows systems can be used to exert endpoint control, including USB devices, and
network quarantine functions in response to events observed by the SIEM offering.
Cautions
SolarWinds LEM is optimized for small to midsize deployments, while other SIEM solutions are a
better fit for largescale deployments.
SolarWinds LEM provides basic statistical and behavior analytics, but has no integration with data
warehouse technologies.
Customers requiring more extensive user and application or Web monitoring must acquire other
SolarWinds products to extend the capabilities available in LEM.
Although LEM includes a native flow capture and display capability, flow data is not available for real
time correlation in LEM.
Return to Top
Splunk
Splunk Enterprise provides log management, search, alerting, realtime correlation and a query language
that supports visualization using more than 100 statistical commands. Splunk is widely deployed by IT
operations and application support teams for log management analytics, monitoring and advanced search
and correlation. Analytics on batch data stored in Hadoop/NoSQL Stores and relational databases is
provided by a separate product called Hunk, and the DB Connect App for bidirectional support for
relational databases. The Splunk App for Enterprise Security provides predefined reports, dashboards,
searches, visualization and realtime monitoring to support security monitoring and compliance reporting
use cases. During 2014, the vendor has remained very visible on SIEM evaluation shortlists. In many
cases, Splunk has already been deployed by IT operations groups. However, there has also been an
expansion in the number of customers deploying the Splunk App for Enterprise Security for standalone
SIEM use cases.
Over the past 12 months, Splunk has released many new functions directed at a major competitive issue
— deployment complexity. Splunk App for Enterprise Security now ships with 68 predefined security
indicators that can be used to construct a custom dashboard, and there are now 40 predefined
dashboards in the security domain menu. Splunk released a report builder with 200 predefined
reports/panels. Splunk now aggregates 18 threat intelligence feeds to enable consolidation into common
watchlists.
Development plans include improved threat detection through trending, anomaly detection, expanded
use of predictive analytics, and discovery of behavioral outliers for assets and users. Splunk is a good fit
for security organizations that require customizable security monitoring and analytics, and is an especially
good fit for use cases that span security and operations, and for deployments with a focus on application
monitoring.
Strengths
Splunk's strong presence in IT operations groups can provide the security organization with early
handson exposure to its general log management and analytics capabilities, "preSIEM"
deployment by operations for critical resources, and inhouse operations support for an expanded
securityfocused deployment.
Splunk's dashboarding and analytics capabilities provide a flexible framework for customization to
meet a variety of event management and log management requirements.
Splunk has builtin support for a large number of external threat intelligence feeds from commercial
and open sources.
Cautions
Splunk provides predefined parsing to a more limited set of IAM vendors than some competitors'
products. Potential buyers should anticipate customization work to handle the parsing of IAM logs
outside Active Directory, LDAP and selected other IAM technologies.
Predefined reporting, while improved in the current release, is still more basic than that of many
competitors.
In cases where operations teams are not using Splunk for operations monitoring (to share
deployment costs), Splunk is often significantly more expensive than competing SIEM solutions.
Return to Top
Tenable Network Security
Tenable Network Security's focus in this market is evolving to emphasize continuous compliance
monitoring based on endpoint state (vulnerabilities, configuration), file activity, network activity and log
data. This evolving emphasis is to augment or complement a broad SIEM deployment, although there are
overlapping use cases. Tenable Network Security supports SIEM use cases through the SecurityCenter
Continuous View (SCCV) console, Nessus, Log Correlation Engine (LCE), and Passive Vulnerability Scanner
(PVS) as a capability of its Integrated Vulnerability, Threat and Compliance Platform. LCE provides log and
event collection, NetFlow monitoring, normalization, analysis, and reporting. SCCV adds the ability to
correlate events with data from Nessus and PVS, in addition to threat list intelligence from thirdparty
providers. Windows and Unix log collection agents can also provide basic file integrity and change
monitoring. Tenable's SIEM customers tend to use the vulnerability scanning and configuration
assessment capabilities as components of their SIEM deployments.

SCCV, LCE, Nessus and PVS are available as software, and SCCV, Nessus and PVS are also available as
hardware or virtual appliances. Network monitoring is available via the NetFlow and raw traffic monitoring
capabilities of LCE, or is enhanced through integration with LCE and the passive network traffic
monitoring provided by PVS. Recent enhancements include packaged content for specific use cases and
policy creation wizards for use cases such as threat management. Development plans include enhanced
user activity monitoring and the introduction of support for business application monitoring. The
combination of SCCV and LCE for SIEM use cases and scanning and monitoring via PVS and Nessus
provides unified management, monitoring, reporting and vulnerability assessment. Tenable's SIEM
solution is a good choice for organizations that want to implement continuous monitoring based on the
assessment of vulnerabilities, security configuration and log data.
Strengths
The integration of SCCV, LCE, Nessus and PVS provides a singlevendor solution for customers
addressing security and compliance requirements that span event and log analysis, vulnerability
assessment, and security configuration auditing.
SCCV and LCE provide statistical analytics, including notification of firsttime events and deviations
from baseline activity levels.
Cautions
LCE does not provide support for comanaged SIEM offerings.
LCE does not provide integration with IAM policy sources, but the vendor indicates there is current
development activity in this area.
LCE does not integrate with major packaged applications.
SecurityCenter lacks workflow integration with enterprise directories.
Organizations that require a broadscope SIEM implementation should consider alternative
solutions.

Tibco Software's LogLogic Log Management Intelligence line of solutions provides log collection and
management capabilities. Tibco also offers additional extensions such as LogLogic Compliance Manager
and LogLogic Analytics. LogLogic is available as a line of physical and virtual appliances, as well as
softwarebased options. Tibco is pursuing a general development strategy that will provide its large
customers with highend analytics, and complexevent processing through the integration of LogLogic
with the Tibco portfolio. Since Tibco's acquisition of LogLogic in 2012, the solution has been integrated
with the wider Tibco portfolio, notably Tibco Spotfire for advanced analytics, Tibco Iris for anomaly
detection and forensics, and Tibco Business Events for complexevent processing.
The LogLogic Database Security Manager and Security Event Manager are not offered anymore, with
some of the Database Activity Monitoring functionality now integrated with LogLogic Analytics, and event
management and functionality divided between Tibco Iris and Tibco Business Events. By itself, LogLogic is
designed as an organizationwide logging as a service (LaaS) platform to gather log, event and machine
data, with only basic SIEM functionality included. In a threat management use case, it is intended to be
used in conjunction with external solutions providing advanced capabilities.
LogLogic is a good fit for use cases focused primarily on log management, providing organizationwide
LaaS, or those that involve log management and event forwarding to an MSSP or a thirdparty event
manager. In addition, customers already using or planning to use other Tibco solutions will benefit from
the integration with LogLogic.
Strengths
The LogLogic line of log management appliances provides competitive log management capabilities
that can be integrated with a wide variety of thirdparty event managers.
LogLogic offers onpremises log management and reporting for deployments that also use an MSSP
for realtime monitoring.
LogLogic, in combination with the greater Tibco portfolio, can provide highscale advanced analytics,
event processing and management, and operational workflow integration.
Cautions
LogLogic lacks advanced security capabilities, such as advanced correlation rules and endpoint
protection technology integration, requiring the purchase of other Tibco products that do not have a
securityspecific focus, or of an additional thirdparty SIEM technology.
LogLogic does not support threat intelligence integration.
Feedback from some users has indicated that the LogLogic transition and integration with the Tibco
portfolio is not fully complete.
LogLogic was not very visible in competitive evaluations, and we have seen more displacements by
SIEM vendors during 2013.

Trustwave
Trustwave's primary business is services for compliance, vulnerability assessment, managed security and
security consulting. Its threat and research capability includes SpiderLabs, which provides research on

security threats and vulnerabilities in support of service delivery and product development. Trustwave
also offers a broad portfolio of security products, including secure Web and email gateways, data loss
prevention (DLP), a Web application firewall, network access control, unified threat management (UTM),
security scanning, and encryption technologies. The core of this portfolio is an SIEM deliverable in several
configurations to meet diverse requirements, from large enterprise, SEMoriented deployments to midsize
deployments with more modest SEM needs.
Trustwave SIEM products are provided as hardware or virtual appliance offerings and can be deployed as
Log Management Enterprise or full function SIEM Enterprise. Trustwave's legacy SIEM Operations Edition
(OE) is deployed as software only with additional optional components such as Advanced Analytics and
Enterprise View. The vendor also offers traditional managed security services through its security
operations centers running the SIEM OE product, and the Managed SIEM offering that includes customer
premises Log Management appliances.
In 2013, Trustwave integrated the Trustwave Threat Correlation threat intelligence service with its SIEM
offerings and added outofthebox NetFlow collection and analysis capabilities. Trustwave also released its
selfhealing network offering that leverages its SIEM to integrate with a number of other Trustwave
security products to provide security automation and active response functionality.
Trustwave is a good fit for midsize organizations that require a combination of complianceoriented
services and SIEM technology.
Strengths
The Trustwave SIEM products include a broad range of deployment formats and service options,
including hybrid options that support customers with limited internal resources for technology
management or analysis.
SIEM OE offers analytics, capacity and customization capabilities appropriate for customers with
largescale event monitoring requirements.
Trustwave's selfsealing network offering leverages Trustwave SIEM to provide autoresponse
capabilities such as quarantining and blacklisting.
Cautions
The variety of options available to mix and match SIEM with other security products and managed
services means that potential SIEM buyers must carefully scope their requirements to enable like
tolike competitive evaluations.
Trustwave SIEM OE users have reported that the custom report wizard can be cumbersome to use,
and manual custom report creation requires SQL and XML skills.
SIEM buyers with requirements to incorporate security technologies from Trustwave's competitors
(for example, IPS, DLP and Web application firewall technologies) must monitor the vendor's ability
to maintain timely support for these technologies with the Trustwave SIEM products and services.
Trustwave is not very visible in competitive evaluations of SIEM among Gartner clients.

Vendors Added and Dropped
We review and adjust our inclusion criteria for Magic Quadrants and MarketScopes as markets change. As
a result of these adjustments, the mix of vendors in any Magic Quadrant or MarketScope may change
over time. A vendor's appearance in a Magic Quadrant or MarketScope one year and not the next does
not necessarily indicate that we have changed our opinion of that vendor. It may be a reflection of a
change in the market and, therefore, changed evaluation criteria, or of a change of focus by that vendor.

Inclusion and Exclusion Criteria
The following criteria had to be met for vendors to be included in the 2014 SIEM Magic Quadrant:
The product must provide SIM and SEM capabilities.
The product must support data capture from heterogeneous data sources, including network

devices, security devices, security programs and servers.
The vendor must appear on the SIEM product evaluation lists of enduser organizations.
The solution must be delivered to the customer environment as a software or appliancebased
product (not a service).
Vendors were excluded if:
They provide SIEM functions that are oriented primarily to data from their own products.
They position their products as an SIEM offering, but the products do not appear on the competitive
shortlists of enduser organizations.
They had less than $13.5 million in SIEM product revenue during 2013.
The solution is delivered exclusively as a managed service.
SIEM is a $1.5 billion market that grew 16% during 2013 — with an expected growth rate of 12.4%
during 2014. For exclusion, Gartner considers revenue and relative visibility of vendors in the market.
The revenue threshold is $13.5 million per year for 2013 (net new license revenue plus maintenance).
Visibility is calculated from the following factors: presence on Gartner client shortlists, presence on
vendorsupplied customer reference shortlists, mentions as a competitor by other SIEM vendors and
search references on gartner.com.

Evaluation Criteria
Ability to Execute
Product or service evaluates the vendor's ability and track record to provide product functions in
areas such as log management, compliance reporting, SEM and deployment simplicity.
Overall viability includes an assessment of the organization's financial health, the financial and
practical success of the overall company, and the likelihood that the business unit will continue to
invest in the SIEM technology segment.
Sales execution/pricing evaluates the technology provider's success in the SIEM market and its
capabilities in presales activities. This includes SIEM revenue and the installed base size, growth
rates for SIEM revenue and the installed base, presales support, and the overall effectiveness of the
sales channel. The level of interest from Gartner clients is also considered.
Market responsiveness/record evaluates the match of the SIEM offering to the functional
requirements stated by buyers at acquisition time, and the vendor's track record in delivering new
functions when they are needed by the market. Also considered is how the vendor differentiates its
offerings from those of its major competitors.
Marketing execution evaluates the SIEM marketing message against our understanding of
customer needs, and also evaluates any variations by industry vertical or geographic segments.
Customer experience is an evaluation of product function or service within production
environments. The evaluation includes ease of deployment, operation, administration, stability,
scalability and vendor support capabilities. This criterion is assessed by conducting qualitative
interviews of vendorprovided reference customers in combination with feedback from Gartner
clients that are using or have completed competitive evaluations of the SIEM offering.
Operations is an evaluation of the organization's service, support and sales capabilities, and
includes an evaluation of these capabilities across multiple geographies.

Completeness of Vision
Market understanding evaluates the ability of the technology provider to understand buyer needs
and to translate those needs into products and services. SIEM vendors that show the highest
degree of market understanding are adapting to customer requirements in areas such as log
management, simplified implementation and support, and compliance reporting, while also meeting

SEM requirements.
Marketing strategy evaluates the vendor's ability to effectively communicate the value and
competitive differentiation of its SIEM offering.
Sales strategy evaluates the vendor's use of direct and indirect sales, marketing, service, and
communications affiliates to extend the scope and depth of market reach.
Offering (product) strategy is the vendor's approach to product development and delivery that
emphasizes functionality and feature sets as they map to current requirements for SIM and SEM.
Development plans during the next 12 to 18 months are also evaluated. Because the SIEM market
is mature, there is little differentiation between most vendors in areas such as support for common
network devices, security devices, OSs and consolidated administration capabilities. In this
evaluation, we neutralized the relative ratings of vendors with capabilities in these areas, but there
is a severe vision penalty for the few vendors that continue to have shortcomings in this area. As in
last year's SIEM vendor evaluation, we place greater weight on current capabilities that aid in
targeted attack detection:
Vendor capabilities and plans for profiling and anomaly detection to complement existing rule
based correlation.
Threat intelligence integration, which includes automated update, filtering, and usage within
rules, alerts and reports.
User activity monitoring capabilities, which include monitoring of administrative policy changes
and integration with IAM technologies, for automated import of access policy (user context) for
use in monitoring.
Data access monitoring capabilities, which include direct monitoring of database logs and
integration with database audit and protection products, DLP integration, and file integrity
monitoring (native capability and integration with thirdparty products).
Application layer monitoring capabilities, including integration with thirdparty applications (for
example, ERP financial and HR applications, and industry vertical applications), for the purpose
of user activity and transaction monitoring at that layer; the external event source integration
interface that is used to define the log format of an organization's inhousedeveloped
applications; and the ability to derive application context from external sources.
Analytics are an important capability to support the early detection of targeted attacks and
breaches. SIEM vendors have long provided query capabilities against the primary storage tiers
of the SIEM technology, and this is the approach that most SIEM customers will use. In order
to be effective for early breach detection, the analytics capability must incorporate context
about users, assets, threats, and network activity, and must also provide query performance
that supports an iterative approach to investigation. Some SIEM vendors have introduced
separate "back stores" designed to hold very large amounts of security event, content and
contextual data, optimized for analysis. A number of SIEM vendors have also built connectors
from the SIEM technology to general purpose big data repositories. Initial deployments of the
"separate analytics back store" approach have been implemented by a small number of Type A
companies.
Integration with advanced threat detection, network monitoring and packet capture
technologies for more effective early breach detection.
Despite the vendor focus on expansion of capability, we continue to heavily weight deployment
simplicity. Users still value this attribute over breadth of coverage beyond the core use cases. There is
a danger of SIEM products (which are already complex) becoming too complex as vendors extend
capabilities. Vendors that are able to provide deployment simplicity as they add function will be the
most successful in the market.
We include an evaluation of hybrid or comanaged options, because a growing number of clients are
asking about the possibility of limited monitoring services for their SIEM technology deployments.
Vertical/industry strategy evaluates vendor strategies to support SIEM requirements that are
specific to industry verticals.
Innovation evaluates the vendor's development and delivery of SIEM technology that is
differentiated from the competition in a way that uniquely meets critical customer requirements.
Product capabilities and customer use in areas such as application layer monitoring, fraud detection
and identityoriented monitoring are evaluated, in addition to other capabilities that are product
specific and are needed and deployed by customers. There is a strong weighting of capabilities that
are needed for security monitoring and targeted attack discovery — user and data access
monitoring, application activity monitoring, ad hoc query and analytics, capabilities/plans for profiling
and anomaly detection, and threat intelligence. We added an evaluation of technology
capabilities/vendor plans for monitoring cloud workloads.
For geographic strategy, although the North American and European SIEM markets produce the
most revenue, growth rates in Latin America and the Asia/Pacific region are much higher (albeit
coming from a much smaller base), driven primarily by threat management and secondarily by
compliance requirements. As a consequence, our overall evaluation of vendors in this Magic
Quadrant includes an evaluation of vendor sales and support strategies for those geographies.

Quadrant Descriptions
Leaders
The SIEM Leaders quadrant is composed of vendors that provide products that are a good functional
match to general market requirements, have been the most successful in building an installed base and
revenue stream within the SIEM market, and have a relatively high viability rating (due to SIEM revenue
or SIEM revenue in combination with revenue from other sources). In addition to providing technology
that is a good match to current customer requirements, Leaders also show evidence of superior vision
and execution for anticipated requirements. They typically have relatively high market share and/or
strong revenue growth, and have demonstrated positive customer feedback for effective SIEM capabilities
and related service and support.
Return to Top
Challengers
The Challengers quadrant is composed of vendors that have a large revenue stream (typically because
the vendor has multiple product and/or service lines), at least a modestsize SIEM customer base and
products that meet a subset of the general market requirements. Vendors in this quadrant typically have
strong execution capabilities, as evidenced by financial resources, a significant sales and brand presence
garnered from the company as a whole or from other factors. However, Challengers have not
demonstrated as rich a capability or track record for their SIEM technologies as vendors in the Leaders
quadrant.
Return to Top
Visionaries
The Visionaries quadrant is composed of vendors that provide products that are a good functional match
to general SIEM market requirements, but have a lower Ability to Execute rating than the Leaders. This
lower rating is typically due to a smaller presence in the SIEM market than the Leaders, as measured by
installed base or revenue size or growth, or by smaller overall company size or general viability.
Return to Top
Niche Players
The Niche Players quadrant is composed primarily of smaller vendors that provide SIEM technology that is
a good match to a specific SIEM use case, a subset of SIEM market requirements. Niche Players focus on
a particular segment of the client base or a more limited product set. Their ability to outperform or
innovate may be affected by this narrow focus. Vendors in this quadrant may have a small installed base
or be limited, according to Gartner's criteria, by a number of factors. These factors may include limited
investments or capabilities, a geographically limited footprint, or other inhibitors to providing a broader set
of capabilities to enterprises now and during the 12month planning horizon. Inclusion in this quadrant
does not reflect negatively on the vendor's value in the more narrowly focused service spectrum.
Return to Top
Context
SIEM technology provides:
SIM — Log management, analytics and compliance reporting
SEM — Realtime monitoring and incident management for securityrelated events from networks,
security devices, systems and applications
SIEM technology is typically deployed to support three primary use cases:
Threat management — Realtime monitoring and reporting of user activity, data access and
application activity, in combination with effective ad hoc query capabilities
Compliance — Log management and compliance reporting
A deployment that provides a mix of threat management and compliance capabilities
Although many SIEM deployments have been funded to address regulatory compliance reporting
requirements, the rise in successful targeted attacks has caused a growing number of organizations to
use SIEM for threat management to improve security monitoring and early breach detection. The SIEM
market is composed of technology providers that support all three use cases; however, there are

variations in the relative level of capability for each use case — in deployment and support complexity, in
the scope of related functions that are also provided, and in product support for capabilities related to
targeted attack detection (such as user activity monitoring, data access monitoring, application activity
monitoring, the use of threat intelligence and anomaly detection). This year's evaluation continues to
more heavily weight capabilities that support targeted attack detection. As a companion to this research,
we evaluate the SIEM technologies of 13 vendors with respect to the three major use cases noted above
(see "Critical Capabilities for Security Information and Event Management").
Organizations should consider SIEM products from vendors in every quadrant of this Magic Quadrant,
based on their specific functional and operational requirements. Product selection decisions should be
driven by organizationspecific requirements in areas such as the relative importance of compliance and
threat management; the scale of the deployment; SIEM product deployment and support complexity; the
IT organization's project deployment and technology support capabilities; identity, data and application
monitoring requirements; and integration with established applications, data monitoring and identity
management infrastructure (see "Toolkit: Security Information and Event Management RFP").
Security managers considering SIEM deployments should first define the requirements for SEM and
reporting. The requirements definition effort should include capabilities that will be needed for subsequent
deployment phases. The project will benefit from the input of other groups, including audit/compliance,
identity administration, IT operations and application owners (see "How to Deploy SIEM Technology").
Organizations should also describe their network and system deployment topology, and assess event
rates, so that prospective SIEM vendors can propose solutions for companyspecific deployment scenarios.
The requirements definition effort should also include phase deployments beyond the initial use case. This
Magic Quadrant evaluates technology providers with respect to the most common technology selection
scenario — an SIEM project that is funded to satisfy a combination of threat monitoring/response and
compliancereporting requirements.
Return to Top
Market Overview
During the past year, demand for SIEM technology has remained strong. During this period, the number
of Gartner inquiry calls from enduser clients with funded SIEM projects increased by 12% over the
previous 12 months,1 and most vendors have reported increases in customers and revenue.2 During
2013, the SIEM market grew from $1.34 billion to approximately $1.5 billion, achieving a growth rate of
about 16%. The primary drivers that were in place at the start of 2013 remain in effect. Breach detection
is the primary driver, and compliance remains a secondary driver. In North America, there continues to
be many new deployments by smaller companies that need to improve monitoring and breach detection.
Compliance reporting also continues as a requirement, but most discussions are securityfocused. There
continue to be new deployments by larger companies that are conservative adopters of technology. Both
of these customer segments place high value on deployment and operational support simplicity. We
continue to see large companies that are reevaluating SIEM vendors to replace SIEM technology
associated with partial, marginal or failed deployments. During this period, we have continued to see a
stronger focus on securitydriven use cases from new and existing customers. Demand for SIEM
technology in Europe and the Asia/Pacific region remains strong, driven by a combination of threat
management and compliance requirements. Growth rates in Asia and Latin America are much higher
than those in the U.S. and Europe. As a consequence, our overall evaluation of vendors in this Magic
Quadrant includes an evaluation of vendor sales and support strategies for those geographies.
The SIEM market is mature and very competitive. We are in a broad adoption phase, in which multiple
vendors can meet the basic log management, compliance and event monitoring requirements of a typical
customer. The greatest area of unmet need is effective targeted attack and breach detection.
Organizations are failing at early breach detection, with more than 92% of breaches undetected by the
breached organization.3 The situation can be improved with stronger threat intelligence, the addition of
behavior profiling and better analytics. Most companies expand their initial SIEM deployments over a
threeyear period to include more event sources and greater use of realtime monitoring. SIEM vendors
have large existing customer bases, and there is an increasing focus on the expansion of SIEM technology
deployments within existing accounts. In general, SIEM vendors are continuing to develop product
capabilities in areas related to breach detection — threat intelligence, anomaly detection and activity
monitoring from the network.
SIEM Vendor Landscape
Fifteen vendors met Gartner's inclusion requirements for the 2014 SIEM Magic Quadrant. Six are point
solution vendors, and nine are vendors that sell additional security or operations products and services.
There were two notable acquisitions in the SIEM market since the last SIEM Magic Quadrant: KEYW
acquired Sensage, and Tibco Software acquired LogLogic. The SIEM market is now dominated by relatively
few large vendors — HP, IBM, McAfee, EMC (RSA) and Splunk — that command about 60% of market
revenue. Other large vendors such as Tibco are also present. A few small vendors continue to do well, but
there will be increasing stress on many of the small remaining vendors. There has been some additional
market consolidation over the past 18 months. Symantec announced the end of sale of its SIEM
technology as of 2 September 2013, and the end of support as of November 2017. EiQ Networks has
shifted its focus away from SIEM technology to security monitoring services and security configuration
assessment. KEYW will no longer sell a fullfunction SIEM product, removing the Sensage technology
from the market. Last year, we updated revenue thresholds and requirements for the relative visibility of
vendors in the market. The revenue threshold is $13.5 million per year for 2013 (net new license
revenue plus maintenance). Visibility is calculated from the following factors: presence on Gartner client
shortlists, presence on vendorsupplied customer reference shortlists, mentions as a competitor by other
SIEM vendors and search references on gartner.com.
SIEM technology is now deployed by a broad set of enterprises. SIEM vendors are increasingly focused on

covering additional use cases, so they can continue to sell additional capabilities to their customer bases.
Some SIEM technology purchase decisions do not include a competitive evaluation, because the
technology is sold by a large vendor in combination with related security, network or operations
management technologies. Many SIEM vendors continue to develop sales channels that can reach the
midsize market in North America. Sales effectiveness in Latin America and Asia/Pacific is becoming more
important as security spending and SIEM deployments increase in these locations.
SIEM vendors have responded to the customer focus on targeted attack and breach detection by
continuing the development of SIEM capabilities in areas such as threat intelligence, analytics, profiling
and anomaly detection, and network activity monitoring (both NetFlow analysis and full packet capture).
Some vendors (IBM, HP and RSA) are also developing integrations with their own big data technologies,
while others (McAfee and Splunk) have described integration plans with thirdparty technologies. A
number of vendors with inhouse security research capabilities (IBM, HP, McAfee, RSA and Trustwave)
provide an integration with proprietary threat intelligence content. Vendors that have both SIEM and
MSSP businesses (HP, IBM, Trustwave and EventTracker) are marketing comanaged SIEM technology
deployments that include varying levels of monitoring services. RSA is executing a strategy to provide a
common platform for log management and packet capture, and also to integrate with its IT governance
risk and compliance management (GRCM) technology. McAfee's strategy is increasingly focused on
technology integration within its own security portfolio and selling SIEM to large enterprises that use its
endpoint security products Several vendors are not included in the Magic Quadrant because of a specific
vertical market focus and/or SIEM revenue and competitive visibility levels:
CorreLog is an SIEM vendor that no longer meets our more stringent revenue and visibility
thresholds.
FairWarning provides privacy breach detection and prevention solutions for the healthcare market
that entail user activity and resource access monitoring at the application layer.
Lookwise is an SIEM vendor that was spun out of S21sec and has a market presence primarily in
Spain and South America. The distinguishing characteristic of Lookwise is the threat intelligence
feeds from S21sec, which are focused on the banking and critical infrastructure sectors. Lookwise
does not meet our more stringent revenue and visibility thresholds.
Tripwire Log Center is focused on augmenting Tripwire capabilities to provide greater system state
intelligence.
Tango/04 provides operational event correlation, business process monitoring and SIEM solutions to
customers in Europe and South America. The vendor no longer meets our more stringent revenue
and visibility thresholds.
Tier3 is an SIEM vendor with a presence primarily in the U.K. and Australia. The distinguishing
characteristic of the technology is its profiling and anomaly detection capabilities. The vendor no
longer meets our more stringent revenue and visibility thresholds.
A few vendors sell solutions that are based on licensed SIEM technology. IBM licenses its technology to
vendors (Juniper Networks and Enterasys Networks) that implement its technology on their own
appliances, and add specific integrations with their respective management infrastructures.
Customer Requirements — Security Monitoring and Compliance Reporting for Systems, Users,
Data and Applications
During the past year, Gartner clients deploying SIEM technology have continued to be primarily focused
on security use cases, even though compliance continues to be an important driver. The primary focus
continues to be targeted attack and breach detection. The security organization often wants to employ
SIEM to improve capabilities for external and internal threat discovery and incident management (see
"Using SIEM for Targeted Attack Detection"). As a consequence, there are requirements for user activity
and resource access monitoring for host systems and applications (see "Effective Security Monitoring
Requires Context"). In this year's SIEM vendor Magic Quadrant evaluation, we continue to place greater
weight on capabilities that aid in targeted attack detection, including support for user activity monitoring,
application activity monitoring, profiling and anomaly detection, threat intelligence, and effective
analytics.
Demand from North American and European clients has remained steady, while the number of
Asia/Pacific SIEM inquiries has been rising. Adoption of SIEM technology by a broad set of companies has
fostered a demand for products that provide predefined security monitoring and compliance reporting
functions, as well as ease of deployment and support. Log management functions have become an
expected and standard component of an SIEM technology architecture.
SIEM solutions should:
Support the realtime collection and analysis of events from host systems, security devices and
network devices, combined with contextual information for threats, users, assets and data
Provide longterm event and context data storage and analytics
Provide predefined functions that can be lightly customized to meet companyspecific requirements
Be as easy as possible to deploy and maintain
Scalability
Scalability is a major consideration with SIEM deployments. For an SIEM technology to meet the
requirements for a given deployment, it must be able to collect, process, store and analyze all security
relevant events. Events that need to be monitored in real time have to be collected and processed in real
time. Event processing includes parsing, filtering, aggregation, correlation, alerting, display, indexing and
writing to the back store. Scalability also includes access to the data for analytics and reporting — even
during peak event periods — with ad hoc query response times that do not preclude the use of an

iterative approach for incident investigation. Query performance needs to hold up, even as the event
store grows over time. We characterize the size of a deployment based on three principal factors:
The number of event sources
The sustained events per second (collected after filtering, if any)
The size of the event back store
We assume a mix of event sources that are dominated by servers but also include firewalls, intrusion
detection sensors and network devices. Some deployments also include a large number of PC endpoints,
but these are not typical, and PC endpoint counts are not included in our totals. The boundaries for small,
midsize and large deployments are not absolute, because some deployments may have a large number of
relatively quiet event sources, while others will have a smaller number of very busy event sources. For
example, a deployment with several busy log sources may exceed the EPS limits set below for a small
deployment, but will still be small architecturally.
Gartner has updated its SIEM deployment size definitions to reflect the increasing scope and scale of
securityfocused deployments. We define a small deployment as one with 300 or fewer event sources, a
sustained EPS rate of 1,500 events per second or less, and a back store sized at 800GB or less. Gartner
defines a medium deployment as one with 400 to 800 event sources, a sustained event rate of 2,000 to
7,000 events per second and a back store of 4TB to 8TB. A large deployment is defined as one with more
than 900 event sources, a sustained event rate of more than 15,000 events per second, and a back
store of 10TB or more. Some very large deployments that have many thousands of event sources,
sustained event rates of more than 25,000 EPS and a back store of more than 50TB. We may indicate
that a vendor's SIEM technology is ideally suited for a small, midsize or large deployment, which means
that the size is a typical or most common successful deployment for that vendor. Every vendor will have
outliers.
SIEM Services
Realtime monitoring and alerting, as well as log collection, query and reporting, are available as a service
offering from MSSPs. Gartner clients indicate a growing interest in using MSSPs to monitor a customer
deployed SIEM. These services are still relatively new, and MSSPs will evolve service offerings in two ways.
We expect lowercost template offerings, where the MSSP will configure and tune the SIEM system based
on a limited number of use cases, with MSSP analysts providing monitoring for selected events and
predefined reporting. We also expect custom offerings, where the MSSP will take over (or share with the
customer) the monitoring and management of SIEM systems, and where the customer has established
extensive alerting and reporting. These more customized services may be delivered with shared resources
or with customerspecific resources working remotely or onsite. We do not include an evaluation of the
service delivery capabilities of MSSPs in this Magic Quadrant. However, we do note SIEM product vendors
that offer remote management or monitoring of their SIEM products. Service providers such as Alert
Logic and Sumo Logic offer SIEM infrastructure as a service for organizations that do not want to deploy
their own SIEM technology.
