Full Definition
OpenVPN is an open-source VPN protocol and software suite that uses SSL/TLS for key exchange and can tunnel traffic over UDP (for speed) or TCP (for reliability through restrictive firewalls). Its open-source nature means it has been extensively audited and is highly configurable — you can run it on any port, use any cipher suite, and apply obfuscation. OpenVPN is slower than newer protocols like WireGuard due to its user-space implementation, but it is one of the most widely supported VPN protocols across routers, servers, and client devices. Many proxy providers offer OpenVPN as a connection option.
