What is WireGuard?

WireGuard is an open‑source VPN protocol and suite of tools that creates encrypted point‑to‑point connections. Designed for simplicity and high performance, it runs in the kernel on major operating systems. Its minimal codebase makes auditing easy, while strong cryptographic primitives ensure privacy. WireGuard can be deployed on servers, desktops, and mobile devices to provide secure remote access and site‑to‑site networking.
