WireGuard 1.1.1 is a free VPN tunnel client for Windows from WireGuard LLC, released under the MIT license. The installer is 3.1 MB and is fetched from the official server, download.wireguard.com. Version 1.1.1 was released and last updated on September 20, 2026.
Who a 3.1 MB tunnel client fits
WireGuard is aimed at people who want a plain, fast VPN tunnel rather than a bundle of extras. The developer describes it as a general purpose VPN meant for devices from embedded interfaces to supercomputers, so it is not tied to one narrow use.
It began as a Linux kernel project and is now also available for Windows, macOS, BSD, iOS and Android. That helps anyone who wants one VPN technology across several kinds of devices.
Speed and simplicity compared with IPsec and OpenVPN
The project aims to be faster, simpler and leaner than IPsec, and considerably more performant than OpenVPN. These are the developer's own goals, and no benchmark figures are given here.
The developer says it uses state-of-the-art cryptography and calls it extremely simple. The page is tagged for network, security and tunnel use, and its category is VPN. The package identifier is WireGuard.WireGuard.
Limits: no server network
WireGuard is free. It is tunnel software, and it does not come with a server network of its own.
The developer notes that the software is under heavy development. If you want a service that comes with its own servers, OpenVPN, OpenVPN Connect, Windscribe, Surfshark, ExpressVPN or Cloudflare One Client are worth comparing.

Is WireGuard safe?
The installer comes straight from the publisher's server, download.wireguard.com, and is not kept on our side. WireGuard LLC develops the software, which uses the MIT license. No independent audit or scan results were available to us, so we cannot say more about its security here.
