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.

  • Minimal attack surface: 4,000 lines vs 70,000+ for OpenVPN
  • Modern cryptography: Uses ChaCha20, Curve25519, BLAKE2s
