| The recent introduction of the Internet Security (IPSec) encryption card allows the CiscoSecure PIX Firewall to support Virtual Private Networks (VPN) across public networks such as the Internet. Users can connect to the network from remote locations using Windows 95/98/2000 or NT client software. The card uses IPSec and Internet Key Exchange (IKE) standards that allow access to the network from the Internet and other public IP networks.
