WireGuard: Overview and Features

WireGuard® is a modern and straightforward VPN protocol renowned for its simplicity, speed, and cutting-edge cryptographic techniques. Unlike IPsec, it prioritizes speed, minimalism, and ease of use without compromising security. Initially released in January 2020, WireGuard has quickly gained recognition for its performance superiority over protocols like OpenVPN.

It's engineered to serve as a versatile VPN solution applicable across a wide spectrum of devices, from embedded interfaces to supercomputers. Initially developed for the Linux kernel, WireGuard is now adaptable across various platforms, including Windows, macOS, BSD, iOS, and Android. Despite being in active development, it's considered one of the most secure, user-friendly, and straightforward VPN solutions available.
