What is Email Security Software?

Email security software protects organizations from cyber threats such as phishing, malware, and spam by filtering incoming and outgoing email traffic. It uses advanced threat detection, encryption, and data loss prevention (DLP) to safeguard sensitive information. These tools also offer features like email authentication (DMARC, SPF, DKIM) and real-time threat intelligence to block emerging attacks. By securing email communications, businesses can prevent data breaches, ensure regulatory compliance, and maintain user trust.
