WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs), and was designed with the goals of ease of use, high speed performance, and low attack surface. It aims for better performance and more power-saving than the IPsec and OpenVPN tunneling protocols. The WireGuard protocol passes traffic over UDP.

In March 2020, the Linux version of the software reached a stable production release and was incorporated into the Linux 5.6 kernel, and backported to earlier Linux kernels in some Linux distributions. The Linux kernel components are licensed under the GNU General Public License(GPL) version 2; other implementations are under GPLv2 or other free/open-source licenses.
