Comparison of VPN Protocols
common as time goes on. It is easy to imagine seeing the number of mass surveillance, hackers, and online trackers by advertising companies that are increasing every time. The era where VPNs are only used by computer enthusiasts and technology is over. However, to get the maximum benefit from your VPN services, it is very important to choose a VPN protocol that suits your needs. Therefore in this article, we will explain the meaning of VPN protocols, the options available in the market, and their advantages and disadvantages.

According to 25pc.com, a VPN, in addition to everything else, encrypts your data traffic before it is sent to the VPN server. The system responsible for the encryption process is usually referred to as the encryption protocol or VPN protocol. The majority of modern VPN providers offer several encryption protocols that users can choose from. It’s important that you choose your encryption protocol wisely. In the end, each protocol has its advantages and disadvantages. There are 6 of the most famous VPN protocols, namely:
- OpenVPN with UDP port
- OpenVPN with TCP port
- PPTP
- IKEv2
- L2TP / IPSec
- Wireguard (This trial protocol is still under development)
In short, to choose the best VPN providers for you, it is important to know the differences between these protocols.
General differences:
OPENVPN
VPN protocols are popular open-source and offer cross-platform capabilities. It offers excellent speed and security that is probably the best of all available VPN protocols. It can exceed the limits of most firewalls, network restrictions, and ISPs.
PPTP
A basic protocol supported by Windows. The configuration is easy to process. Generally fast Supported by many devices and systems
L2TP / IPSEC
Tunneling protocol that uses the IPSec protocol for security and encryption. L2TP only offers UDP ports (which are notorious for being faster, but less reliable and less secure than other TCP ports). The configuration is easy to process. It can exceed the limits of most firewalls, network restrictions, and ISPs.
IKEV2
Like L2TP, IKEv2 is a tunneling protocol that relies on the IPSec encryption system. However, this protocol is supported by a smaller number of devices and systems. The configuration is easy to do. Good speed.
WIREGUARD
A new open-source protocol, currently in an experimental phase. This protocol is still under development but was praised for its speed and small codebase. Small codebase (easy to audit and smaller surface to attack). According to the developer and some critics, Wireguard is a protocol that is fast and easy to use.
In short, it is very important to choose the right VPN protocol for you. Each protocol has advantages and disadvantages of each. In many cases, OpenVPN is the best choice for you. PPTP is a protocol that we recommend not to use because of the relatively low encryption level. However, you can try this protocol when privacy and security are not your top priority, for example when you want to unblock streaming. If OpenVPN is not supported and doesn’t work well for any reason, you might consider using L2TP / IPSec or IKEv2.
