![]() ![]() ![]() The most important thing is to pick one that best suits your needs. You now know everything about VPN protocols a VPN user might need. In truth, one protocol would be enough to provide a good VPN service, but due to the differences in compatibility for routers and different OS (operating systems), we provide all three. There is no real reason to use any other VPN protocols outside The Big Three. Most older protocols outside of WireGuard, OpenVPN, and IKEv2 are outdated full of vulnerabilities, and obsolete. Why WireGuard, OpenVPN, and IKEv2 are the best VPN protocols While UDP works best for most users, the general advice is to try them both out and use the one that provides you with a smoother connection. UDP does it faster by throwing everything at you and then arranging them to work. TCP ensures a stable connection by making sure all data packets arrive in order. TCP and UDP are essentially different transport layer protocols that OpenVPN can use to establish a VPN connection. OpenVPN TCP and OpenVPN UDP are not two separate VPN protocols. Still, that comes at the price of speed as to relay every bit of information, TCP takes a bit longer than, say, UDP (User Datagram Protocol). OpenVPN TCP (Transmission Control Protocol) tends to be the most stable protocol, especially when dealing with unreliable networks. Most of our tests and user feedback show that the connection speed competition comes down to the wire between WireGuard and IKEv2 (pun fully intended). The geographical distance between you and the VPN server.Your device compatibility and quality.The speed of your internet connection.Contrary to popular belief, VPN protocols themselves don’t have a dramatic impact on your connection speed. ![]()
