PPTP

PPTP is one of the oldest VPN protocols and should be avoided for any security-sensitive use case. While it is incredibly easy to set up and compatible with almost everything, its cryptographic weaknesses have been thoroughly documented. It offers minimal security guarantees in 2025 and should only be used for non-sensitive, purely diagnostic, or educational purposes where security is explicitly n...

GRE Tunneling

Generic Routing Encapsulation (GRE) is a tunneling protocol used to encapsulate a network layer protocol within another. While not a VPN itself, it is often used *underneath* a VPN or tunneling solution to carry non-IP traffic or to simplify routing across complex network boundaries. It requires a separate encryption layer (like IPsec) to be secure, making it a foundational networking tool rather...
