Client access VPNs are an extremely popular tool for providing external users access to a corporate network. The two most used technologies for this are IPSec VPNs and SSL VPNs. IPSec VPNs use the IPSec protocol to create the VPN tunnel. IPSec VPNs operate at the network layer of the OSI model. When a client connects through an IPSec VPN, he or she has virtually full access to the network. Clients appear as just another node on the network. IPSec VPNs have been around for a long time. For years, IPSec VPNs were the standard for client access VPNs. SSL VPNs have just begun to grow in popularity fairly recently.
