WireGuard
WireGuard is a modern, lightweight VPN protocol known for fast speeds, strong up-to-date cryptography, and a very small codebase.
WireGuard explained
WireGuard is a VPN tunneling protocol designed to be simpler and faster than older options. Its code is a fraction of the size of OpenVPN, which makes it easier to audit and less prone to bugs, and it uses fixed, modern cryptography rather than a sprawl of configurable options.
The result is excellent speed and quick connection times, which is why many providers build their fastest offerings on it, sometimes under custom names. Its main historical concern, static IP handling, is solved by provider-side implementations that add a privacy layer on top.
Examples
- 01A VPN advertising its fastest speeds using a WireGuard-based protocol
- 02Near-instant reconnection when switching networks
- 03Streaming in 4K over a WireGuard tunnel with minimal slowdown

Frequently asked questions
It is a modern VPN protocol built for speed and simplicity, with a small auditable codebase and fixed, up-to-date cryptography, now used by many leading VPNs.
Generally yes. Its lean design and efficient cryptography usually deliver higher speeds and faster connection times than OpenVPN, especially on mobile.
Yes. It uses strong, modern cryptography and its small codebase is easier to audit, which reduces the chance of hidden vulnerabilities.
Providers often build a custom implementation on top of WireGuard to add privacy features like dynamic IP assignment, and brand it under their own name.
WireGuard itself can retain some connection state, so reputable VPNs add a layer that avoids storing identifying data, which is why the provider no-logs policy still matters.
