WebIPSec: a framework that provides security on layer three of the OSI model. PPTP: an old VPN protocol that uses PPP and GRE, insecure and should not be used anymore. L2TP: a VPN protocol that tunnels layer two traffic, does not offer any encryption so should be used together with IPsec. WebIPsec is used for protecting sensitive data, such as financial transactions, medical records and corporate communications, as it's transmitted across the network. It's also used to secure virtual private networks ( VPNs ), where IPsec tunneling encrypts all data sent between two endpoints.
