What are the most common VPN protocols?

  • OpenVPN: it is one of the most used, it is very versatile and offers a great balance between performance, speed and reliability.
  • IKEv2: It is great for mobile devices as it automatically reconnects in case of connection loss, which is common in mobile networks. Speed ​​is one of its biggest advantages, but it has a more complicated setup procedure.
  • WireGuard: a simple and easy to implement open-source protocol, very fast and efficient.
  • L2TP / IPSec: it is an alternative protocol to OpenVPN, it does everything well, but it does not excel in anything, in general, it is appreciated.
  • SSTP: This is a proprietary protocol from Microsoft, which therefore works and integrates very well with Windows. If you have other operating systems it is almost impossible to integrate, so you will have to turn to something else.
  • PPTP: an old and no longer updated protocol, with decent speed, but little attention to security, better to avoid VPNs that use this protocol.
