Encrypting Communication: IPsec

IP Security Protocol (IPsec) is a protocol for encrypted communication over networks such as the Internet. While TLS encrypted communication is a technology for encryption with specific applications such as web browsers and e-mail clients, IPsec communication encrypts at an protocol level, enabling more versatile security. It is supported only when the IP address setting is IPv6. IPv4 is not supported.
