WireGuard — The Fastest Modern VPN Protocol
WireGuard is a next-generation VPN protocol offering faster speeds and simpler code than OpenVPN while maintaining top security.
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.
