What is the difference between VPN and IPsec?
SSL VPNs. The major difference between an IPsec VPN and an SSL VPN comes down to the network layers at which encryption and authentication are performed. IPsec operates at the network layer and can be used to encrypt data being sent between any systems that can be identified by IP addresses.
