The related VPN application finishes the system login and IPSec operates the network coating (layer 3) of the Open Programs Interconnection model.
SSL VPNs provide an alternative to IPSec and utilize the internet windows rather than VPN clients for individual system login. They are also a cheaper substitute because they use the SSL system, which operates at an increased stage compared to the IPSec, to construct in methods into normal internet surfers and servers.
