Which feature of AnyConnect provides you the ability to identify data breaches as they happen?

Flexible AAA Options refers to AnyConnect's support for multiple authentication, authorization, and accounting backends, which governs access control but provides no telemetry for detecting breaches.

NVM captures detailed context for every network flow from the endpoint - including process name, user identity, device posture, and destination - and streams it to a SIEM or collector, giving analysts the real-time visibility required to identify unauthorized data transfers and active breaches.

Differentiated Mobile Access tailors VPN behavior and policies for mobile devices on a per-app or per-device basis, addressing connectivity management rather than threat or breach detection.

Trusted Network Detection automatically connects or disconnects the VPN based on whether the endpoint is on a recognized trusted network, which is a connectivity automation feature unrelated to identifying data breaches.
