The SSL VPN Client (SVC) is a VPN tunneling technology that gives remote users the benefits of an IPsec VPN client without the need for network administrators to install and configure IPsec VPN clients on remote computers. The SVC uses the SSL encryption that is already present on the remote computer as well as the WebVPN login and authentication of the security appliance.
In order to establish an SVC session, you must enter the IP address of a WebVPN interface of the security appliance in the browser, and the browser connects to that interface and displays the WebVPN login screen. If you satisfy the login and authentication, and the security appliance identifies the user as requiring the SVC, the security appliance downloads the SVC to the remote computer. If the security appliance identifies you to have the option to use the SVC, the security appliance downloads the SVC to the remote computer while it presents a link on the user window to skip the SVC installation.
After it is downloaded, the SVC installs and configures itself, and then the SVC either remains or uninstalls itself, which depends on the configuration, from the remote computer when the connection terminates.
