How does AnyConnect provide highly secure access for select enterprise mobile apps?

Application Visibility and Control (AVC) is a network analytics and QoS feature used to classify and manage application traffic on the network infrastructure side, not a client-side VPN capability for mobile apps.

Secure Layer 2 Network Access refers to 802.1X-based wired or wireless authentication and network access control, not a VPN or per-application tunneling mechanism on mobile devices.

Identity Service Engine is the policy and AAA server infrastructure component; it is not a client-side feature and does not itself establish VPN tunnels for mobile applications.

Per App VPN in AnyConnect allows IT administrators to configure specific managed mobile applications to automatically connect through the VPN tunnel while other apps use direct internet access. This limits the VPN attack surface, reduces bandwidth consumption, and ensures sensitive enterprise app traffic is encrypted and controlled, which is the mechanism for highly secure access for select apps.
