About:
OpenVPN is a full-featured, open-source secure tunneling solution that implements OSI layer 2 or 3 secure network extension. It uses custom security protocols utilizing SSL/TLS for key exchange and encapsulates traffic within a single UDP or TCP port. This allows for secure remote access, site-to-site connectivity, and complex network routing across untrusted networks.
Key Features:
  • SSL/TLS-based secure key exchange
  • Support for UDP and TCP transport
  • Flexible routing and bridging capabilities
  • Cross-platform compatibility
  • Strong encryption ciphers
Use Cases:
  • Secure remote access for telecommuters
  • Site-to-site VPN connections
  • Protecting traffic on public Wi-Fi networks
Alternatives:
  • WireGuard – Newer, faster, and simpler to configure, but with fewer built-in features.
  • OpenSSH – Provides basic tunneling capabilities but lacks full VPN network stack features.
