What is WireGuard?
A modern, lean VPN protocol that delivers the fastest speeds in our UK testing.
By VPNGuide Editorial Team · Updated 20 September 2026
WireGuard is a VPN protocol built from roughly 4,000 lines of code, compared with hundreds of thousands in OpenVPN. The smaller surface is easier to audit and noticeably faster.\n\nProviders often ship a modified build, such as NordVPN's NordLynx, to address WireGuard's default handling of assigned addresses.
