WireGuard — The Fastest Modern VPN Protocol

What Is WireGuard?

WireGuard is a modern VPN protocol designed for simplicity and performance. With roughly 4,000 lines of code (compared to OpenVPN's 70,000+), it is easier to audit, faster to connect, and delivers better throughput.

Key Features

  • Blazing speed: Significantly faster than OpenVPN and IKEv2
  • Minimal attack surface: 4,000 lines vs 70,000+ for OpenVPN
  • Modern cryptography: Uses ChaCha20, Curve25519, BLAKE2s
  • Built into Linux kernel: Native performance on Linux systems
  • Instant connections: Sub-second handshake times

WireGuard is the default protocol on all LimeVPN apps.
