IPsec features

IPsec is the most secure, commercially available method to connect network remote clients and sites. IPsec was designed to provide a secure and robust mechanism to transfer the IP packets privately across networks. IPsec has a number of features baked into the protocol, which makes it so secure and robust. An authentication mechanism inherent in the IPsec protocol verifies that the packet received is actually from the claimed sender. IPsec uses strong cryptography to assert and verify the integrity of data. This ensures that the contents of the packet did not change during transit. And, of course, with the help of encryption, IPsec ensures confidentiality. It conceals the message's content through encryption while it is in ...
