Cisco AnyConnect

The AnyConnect VPN client is a Java-based application, which establishes a SSL-encrypted tunnel to Cisco ASA 5500 gateways. With this tool communication over otherwise insecure networks like the unencrypted networks like GoeMobile can be secured.

Usage of Apple Bonjour for Windows may cause connection problems with the Cisco AnyConnect client (KB970313).
