Cisco Secure Client-AnyConnect

Establishing an encrypted link to enterprise resources allows mobile workers to maintain seamless access to business email, virtual desktop sessions, and internal corporate software. Formerly known as AnyConnect, Cisco Secure Client-AnyConnect handles this connectivity by automatically negotiating tunnel methods based on current network constraints, supporting both TLS and DTLS alongside IPsec/IKEv2 protocols. It is designed to preserve active sessions through IP address shifts, unexpected connection dropouts, or device standby states, making it a dedicated remote-access tool for corporate environments.

Tunnel Optimization and Roaming Capabilities

The client automatically adapts its tunneling approach to select the most efficient protocol available, relying on DTLS to optimize the connection whenever possible. Remote workers who move across networks benefit from built-in network roaming, which restores dropped tunnels without forcing the user to manually re-authenticate after every interface change. For environment setup and access control, security policies can be defined directly on the client or pushed automatically from the headend security gateway, accompanied by certificate deployment handled through integrated SCEP or a dedicated URI import handler.

Deployment Prerequisites and Licensing

Operating this software requires dedicated enterprise infrastructure and active licensing. The client is strictly designed for Cisco headends and cannot be deployed against third-party equipment. Enterprise administrators must run Cisco Adaptive Security Appliance (ASA) Boot image 8.0(4) or later and hold active Plus, Apex, or VPN Only licenses, while older Essentials or Premium with Mobile licenses are no longer accepted. For organizations incorporating DNS-layer protection, the Cisco Umbrella module can be added to the software, though this requires separate Umbrella licensing to function.

Platform Constraints and Excluded Features

This package omits several capabilities present on other platforms, meaning administrators and users must plan around explicit limitations. The software does not support Filter Support, Trusted Network Detection, Split Exclude, or Local LAN Exception, and the Secure Gateway Web Portal cannot be reached while the tunnel is active. Furthermore, operating system boundaries prevent Split DNS from functioning on Android 7.x and 8.x, and occasional interface freezes have been identified within the built-in Diagnostics screen.
