Internet Protocol Security (IPsec) is a suite of protocols designed to ensure secure communication over Internet Protocol (IP) networks. IPsec provides essential security features such as data integrity, authentication, and encryption, which protect data packets as they travel across potentially untrusted networks, like the internet. It operates at the network layer, making it a versatile solution that can secure any application traffic without requiring changes to the individual applications.
