• Easily manage access control and segmentation while maintaining compliance.
• Create and manage policies in an easy-to-use matrix.
• Reduce the need for costly network re-architecture by automating firewall rules and access control list (ACL) administration.

Microsoft Defender External Attack Surface Management is particularly well-suited for discovering, inventorying, and continuously monitoring the external attack surface, especially in environments with heavy Microsoft adoption. It is less suitable as a standalone solution for internal scanning, real-time attack detection, automated remediation, or advanced application testing.
