What is IPsec?

Several protocols collectively known as IPsec are used to establish secure connections between devices. It contributes to the security of data transmitted over open networks. It works by encrypting IP packets and authenticating the source from which the packets originate. IPsec is frequently used to set up VPNs.

Internet Protocol and secure are both abbreviated as IP and sec, respectively, in the term "IPsec." The main routing protocol used on the Internet is called the Internet Protocol, and it uses IP addresses to specify where data will go. Authentication and encryption are added to this process by IPsec, making it more secure.
