WireGuard is a modern, open source VPN protocol designed to be simple, fast, and secure. Unlike older protocols, WireGuard uses state-of-the-art cryptography and a minimalist codebase, making it easier to audit and maintain. It operates at the network layer and is implemented directly in the Linux kernel, which boosts performance and reduces latency. WireGuard is cross-platform, supporting Windows, macOS, Linux, Android, and iOS. Its configuration is straightforward, relying on public keys for identification and authentication. WireGuard is widely praised for its efficiency, strong security, and ease of use, making it a popular choice for both personal and enterprise VPN solutions.
