WireGuard — fast, modern, secure kernel VPN tunnel
by Jason A. Donenfeld of Edge Security
WireGuard is a novel VPN that runs inside the Linux Kernel and utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPSec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. It runs over UDP.
