SonicWALL SSL-VPN NetExtender 

Generates secure points for accessing the subnet on an internal network, without requiring the remote users to install client applications. Decreases the login times for subsequent users and gives full access to the network's resources.

NetExtender creates a virtual adapter for secure point-to-point access to any allowed host or subnet on the internal network. Unlike the stateless nature of the traditional SSL VPN, NetExtender stays resident on the client machine even after the connection is closed. The advantage of running NetExtender as a resident application on the remote system is that it speeds up login times in subsequent uses.
