About
WireGuard is a VPN protocol and tunnel implementation that uses modern cryptographic primitives (Curve25519, ChaCha20, Poly1305, BLAKE2) to create secure network interfaces configured via simple public-key exchange, similar to SSH. It runs in the Linux kernel for high performance and is designed to be small and auditable compared to IPsec or OpenVPN, while supporting roaming across IP addresses and cross-platform deployment on Windows, macOS, BSD, iOS, and Android.
What it does
This is a lightweight virtual private networking system that creates secure, encrypted tunnels between devices by exchanging simple keys, similar to setting up remote-access credentials. It runs across desktop and mobile platforms, aims for high speed, and lets connected devices keep working even as their network address changes.
Stated on the product site
- License
- Licensing varies by component: the kernel-side components use GPLv2, while other parts of the project use MIT, BSD, Apache 2.0, or GPL depending on context.
- Platform support
- The vendor states the tool started on Linux and is now cross-platform, also supporting Windows, macOS, BSD, iOS, and Android.
- Configuration
- The vendor describes configuration as happening through a dedicated command-line utility alongside ordinary operating-system networking tools, rather than through a proprietary control panel.
- Container support
- The vendor states the tunnel interface can be moved into an isolated container network namespace so that a container's only path to the network runs through the encrypted tunnel.
Not stated on the site
- The page does not state pricing or whether any paid tier or commercial licensing option exists.
- The page does not describe a graphical user interface, so it is unclear whether one is offered beyond command-line configuration.
- The page does not specify minimum operating system versions or hardware requirements for each supported platform.
