Types of VPN Protocols Explained

Here are the most common types of VPN protocols being used



UDP (User Datagram Protocol) is used as an alternative to the TCP to establish low-latency and loss-tolerating connections over the Internet.



TCP (Transmission Control Protocol) is used as a standard to define how network conversation through which application programs exchange data, takes place.



The data being transmitted through the L2TP/IPSec protocol gets authenticated twice which slows down the VPN performance a bit but ensures the highest security.



IKEv2 (Internet Key Exchange version 2) handles request and response actions by ensuring that the traffic is secure through the establishment of Security Association attribute.



The IP security (IPSec) is a standard suite of protocols existing between two different communication points across the IP network.



OpenVPN is a most secure VPN protocol which relies on SSL/TLS for establishing highly encrypted connections.
