URGENT: CISA Calls on Organizations to Swiftly Embrace Microsegmentation On July 29, 2025, the Cybersecurity and Infrastructure Security Agency (CISA) published “Microsegmentation in Zero Trust, Part One: Introduction and Planning” — setting a renewed standard for securing modern IT environments under the Zero Trust principle. Microsegmentation is central to Zero Trust Architecture, dramatically reducing attack surfaces, limiting lateral movement, and boosting visibility. CISA recommends a risk‑based, phased approach: from asset discovery to dependency mapping, policy design, and incremental deployment. This is not guidance for next year—it’s a mission-critical directive for today. Whether you're in public or private sector IT, the time to plan and act is now. At Stratejm, a Bell Canada company, we're proud to partner with Illumio, the original microsegmentation specialist and leading Zero Trust Segmentation platform recognized by Forrester. Together, we are bridging theory and action. How Stratejm + Illumio empower your Zero Trust journey: 1. Instant visibility: Rapid insight into application and workload communication patterns . 2. Automated policy recommendations: AI-driven guidance helps eliminate guesswork . 3. Resilient enforcement: Real‑time segmentation across data centers, hybrid cloud, containers, endpoints, IoT and OT. 4. Breach containment: Minimize blast radius during active threats with adaptive policies . Key Steps You Should Take Now: 1. Join cross-functional teams to manage asset mapping and policy design Prioritize segmentation of your critical assets. 2. Start with a low‑risk or non‑production pilot, refine policies based on actual traffic flows. 3. Deploy Illumio with Stratejm’s guidance to operationalize safe, scalable segmentation. 4. Monitor continuously and iterate to adapt as your environment evolves. Stratejm + Illumio deliver CISA‑aligned, zero‑trust‑ready microsegmentation—fast. In a threat landscape where breaches can escalate in minutes, delaying is not an option. Ready to act? Let's talk about how Stratejm and Illumio can help you implement zero trust microsegmentation that works from day one. #ZeroTrust #Microsegmentation #CISA #Cybersecurity #Stratejm #Illumio #BreachContainment #SecurityResilience

This is the wake-up call many needed. CISA’s directive makes it clear: microsegmentation is essential NOW, not later. Stratejm and Illumio are showing exactly how to turn Zero Trust from concept into action with visibility, policy automation, and, ransomware containment. If you're relying on legacy controls, it’s time to rethink and evolve your strategy. Together, let’s make segmentation and ransomware containment real, fast, and effective.

Thank you John for your partnership with Illumio. This great partnership with Stratejm a Bell Canada company embarks the needs for the new era of cybersecurity breach containment solution. Zero Trust Microsegmentation is the only practice to stop the lateral movement, boosting the visibility and stop the ransomware. We at Illumio value Stratejm-Bell Canada partnership and we fully endorse and support the initiative. This call by CISA is urgent as The rules of cybersecurity have changed and the breaches are inevitable. Thanks again to Stratejm team.
