Which Policy and Access solution technology combines posture checks and authentication across wired, wireless, and VPN networks?

Cisco AnyConnect integrates with Cisco Identity Services Engine (ISE) to perform posture checks - verifying endpoint compliance such as OS patch level and antivirus status - and enforces authentication policy uniformly across wired 802.1X, wireless, and VPN connections. This makes it the only option listed that spans all three access methods with both posture and authentication capabilities. No other listed product combines these functions into a single endpoint agent.

Next Generation IPS inspects network traffic for exploit signatures and anomalies but does not perform endpoint posture checks or manage user authentication.

Cisco Stealthwatch is a network traffic analysis platform focused on behavioral anomaly detection and flow telemetry, not posture assessment or access authentication.

The ASA 2100 series is a hardware firewall appliance that enforces perimeter security policies but does not function as a posture or authentication agent across access methods.
