OpenVPN — The Most Trusted VPN Protocol

What Is OpenVPN?

OpenVPN is an open-source VPN protocol that uses SSL/TLS for key exchange and supports AES-256 encryption. It has been the industry standard for over 20 years, trusted for its security, reliability, and extensive audit history.

Advantages

  • Open source: Fully auditable code with no hidden backdoors
  • Highly configurable: Supports custom encryption, ports, and authentication
  • Firewall-friendly: Can run on TCP port 443 (HTTPS), making it hard to block
  • Cross-platform: Works on Windows, macOS, Linux, Android, iOS, and routers

OpenVPN vs WireGuard

While WireGuard is faster and simpler, OpenVPN remains the go-to for maximum compatibility and configurability. LimeVPN supports both.
