IPSec (Internet Protocol Security) is a suite of protocols that is accepted as an industry standard and provides secure data transmission over layer 3 of the OSI model. IPSec can be used to encrypt and authenticate data packets, providing data confidentiality, integrity, and authentication. L2TP and PPTP are both VPN protocols that operate at layer 2 and layer 3 respectively. GRE (Generic Routing Encapsulation) is a tunneling protocol that does not provide encryption or authentication.
