WireGuard is a modern, open-source virtual private network (VPN) protocol designed for simplicity and high performance. It aims to provide a secure connection over the internet by encrypting data, making it difficult for unauthorized users to access sensitive information. Unlike traditional VPN protocols, WireGuard uses a minimal codebase, which enhances security and makes it easier to audit. It operates at the network layer and is compatible with various operating systems, including Linux, Windows, and macOS, allowing users to establish secure connections quickly and efficiently.
