WireGuard
FreeModern, ultra-fast VPN protocol used as the foundation for many business solutions
🌐Site-to-Site VPNAbout WireGuard
WireGuard is an open-source VPN protocol known for its simplicity, speed, and strong cryptography. With just 4,000 lines of code (vs. 100,000+ for OpenVPN), it has a smaller attack surface and is easier to audit. Many modern VPN products (Tailscale, NordLayer, etc.) are built on WireGuard.
What's Great
- ✓Just 4,000 lines of code — dramatically smaller attack surface than OpenVPN
- ✓Fastest VPN protocol available with minimal latency overhead
- ✓Strong modern cryptography with no configuration complexity
- ✓Free and open-source — included in the Linux kernel since 5.6
- ✓Foundation protocol for Tailscale, NordLayer, and many modern VPN products
Watch Out For
- !Raw protocol — no built-in user management, admin console, or logging
- !Requires technical expertise to configure and manage directly
- !No native dynamic IP handling — peers need stable endpoints or workarounds
- !Lacks the enterprise features (SSO, SCIM, dashboards) of managed VPN products
