Comparison of VPN Protocols. OpenVPN, IKEv2, PPTP, WireGuard, SoftEther and Others


VPN creates a secure and encrypted tunnel over the data you transmit online. The formation and encryption level of that tunnel could be different. This formation, sets of programs, and processes to create the tunnel are known as VPN protocols. This article discusses a comparison of VPN protocols by listing their different features.

The level to which you get the encryption, security, and connection speed with a VPN largely depend on what VPN protocol is in use. This is because VPN protocols are different in terms of performance, capabilities, and strength.

How to Choose the Best VPN Protocol?

VPN protocols can be classified into two different kinds. One which offers higher security and others which are good in terms of speed. This is obvious in most cases that higher security will lead to a lower level of speed. Therefore, VPN protocols with a higher level of encryption offer lower speed.

Protocols with a weaker encryption level have a wider data tunnel and data packets move faster and easily resulting in a better speed. Similarly, this is the opposite case for the protocols with a higher level of security. There is a higher level of encryption so their tunnel gets narrower and resulting in a slower speed. Here is a list of most commonly used VPN protocols.

    • OpenVPN
    • L2TP/IPSec
    • PPTP
    • IKEv2/IPSec
    • SSTP
    • WireGuard
    • SoftEther

The following chart shows a comparison of VPN protocols in terms of speed, encryption, stability, media streaming capability, and P2P file sharing

What is the Fastest VPN Protocol?

Due to the low level of encryption, PPTP is considered faster than other VPN protocols. When you do not care much about online security and want a VPN for streaming or just changing your IP/ location, then PPTP is a smart choice. Moreover, WireGuard, relatively a new VPN protocol, is also considered a fast VPN protocol with a good level of encryption. IKEv2 is also fast and secure. While OpenVPN and SSTP are slower as compared to other VPN protocols. So in terms of speed, PPTP is the Fastest VPN protocol.

What is the Most Secure VPN Protocol?

OpenVPN is ranked as the most secure VPN protocol while PPTP is the least secure VPN protocol. OpenVPN uses a very high level of encryption and digital certificates. OpenVPN also allows customization of configuration and encryption levels to get extra security and speed.

What is the Best VPN Protocol for P2P File Sharing / Torrenting?

For P2P file sharing and torrenting, only a VPN protocol with higher encryption should be used. IKEv2 and OpenVPN are usually recommended for P2P file-sharing or torrenting. IKEv2 is fast and secure as well and recommended for P2P file-sharing. However, IKEv2 is not compatible with many old versions of operating systems. In that case, OpenVPN is a smart choice that is supported by most of the old and modern operating system versions and is highly secure as well.

What is the Most Stable VPN Protocol?

IKEv2 is ranked as the most stable protocol. It offers a very stable as well as highly encrypted connection.

What is the Best VPN With My Choice of Protocol?

After going through the comparison of VPN protocols, if you are looking for a VPN with a very wide variety of protocols, then FastestVPN is a smart choice that offers PPTP, OpenVPN, IKEv2, L2TP, IPSec, and OpenConnect. For modern protocols such as WireGuard, NordVPN is one of the best VPN services. Further, PureVPN also offers a wide range of protocols such as IKEv2, IPSec, OpenVPN, L2TP. Moreover, PureVPN is one of the VPN services with the most number of VPN servers around the world. Here you can visit the best VPN deals listed by Free VPN tutorials.
