Comparison of VPN protocols. OpenVPN, IKEv2, L2TP, PPTP, WireGuard, SSTP, IPSec, SoftEther
/
A VPN creates a secure, encrypted tunnel for the data you transmit over the Internet. The level of configuration and encryption for this tunnel can be different. This configuration and combinations of programs and processes for creating the tunnel are known as VPN protocols.
The level of encryption, security, and connection speed you get with a VPN largely depends on the VPN protocol used. This is because VPN protocols differ in terms of performance, capabilities, and strength.
How do you choose the best VPN protocol?
VPN protocols can be categorized into two different types. One provides higher security and the other is good in terms of speed. It is clear in most cases that higher security will result in lower level of speed. Therefore, VPN protocols with a higher level of encryption provide a lower speed.
VPN protocols with weaker encryption level have a wider data tunnel, data packets move faster and easily lead to a better speed. Likewise, this is the opposite case for protocols with a higher level of security. There is a higher level of encryption, so their tunnel narrows and leads to a slower speed. Below is a list of the most used VPN protocols.
-
- OpenVPN
- L2TP / IPSec
- PPTP
- IKEv2 / IPSec
- SSTP
- Wireguard
- SoftEther
The following chart shows a comparison of these protocols in terms of speed, encryption, stability, media streaming capability, and P2P file sharing.
VPN Protocol Comparison
| VPN protocol | encryption | Speed | stability | flow | P2P File Sharing |
|---|---|---|---|---|---|
| PPTP | poor | Fast | Hassan | Hassan | Average |
| OpenVPN TCP | Hassan | Average | Hassan | Average | Hassan |
| OpenVPN UDP | Hassan | Fast | Average | Hassan | Hassan |
| IKEv2 / IPsec | Hassan | Fast | Hassan | Hassan | Hassan |
| L2TP / IPSec | Average | Average | Hassan | Hassan | Average |
| IPsec | Hassan | Average | Hassan | Hassan | Hassan |
| SSTP | Hassan | Average | Average | Average | Hassan |
| Wireguard | Hassan | Fast | Hassan | Hassan | Hassan |
| SoftEther | Hassan | Fast | Hassan | Average | Average |
What is the fastest VPN protocol?
Due to the low level of encryption, PPTP is faster than other VPN protocols. When you don’t care much about online security and want a VPN for streaming or just to change your IP address/location, PPTP is a smart choice. Moreover, WireGuard, which is a relatively new VPN protocol, is a fast VPN protocol with a good level of encryption. IKEv2 is also fast and secure. While OpenVPN and SSTP are slower 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 rated 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 for customization of configuration and encryption levels for added security and speed.
What is the best VPN protocol for P2P/torrent file sharing?
For P2P file sharing and torrenting activities, only VPN protocol with higher encryption should be used. IKEv2 and OpenVPN are usually recommended for P2P or torrent file sharing. IKEv2 is also fast and secure, and is recommended for P2P file sharing. However, IKEv2 is not compatible with many older versions of operating systems. In this case, OpenVPN is a smart option that is supported by most versions of both old and new operating systems and is also very secure.
What is the most stable VPN protocol?
IKEv2 has been rated as the most stable protocol. It provides a very stable and highly encrypted connection.
What is the best VPN with my choice of protocol?
If you are looking for a VPN with a very diverse set of protocols, FastestVPN is a smart choice that offers PPTP, OpenVPN, IKEv2, L2TP, IPSec, and OpenConnect. For modern protocols like WireGuard, NordVPN is one of the best VPN services. Moreover, PureVPN also offers a wide range of protocols such as IKEv2, IPSec, OpenVPN, and L2TP. Moreover, PureVPN is one of the VPN services with the largest number of VPN servers around the world.
