VPN services use encryption protocols to secure your traffic and keep you safe when you are browsing the internet. Here are some of the most common protocols that VPN services use and the features that distinguish them.


L2TP stands for Layer 2 Tunnel Protocol. In general, VPN services usually combine this form of protocol with the common Internet Protocol Security (IPSec). That is why many VPN services indicate that they use the L2TP/IPSec protocol to secure the traffic of their clients. The main thing about this protocol that you need to keep in mind is that it is better than the standard PPTP protocol. L2TP is more secure and faster than PPTP. However, some firewalls may successfully block 2TP.


PPTP is Point-to-Point Tunnelling Protocol. By far, this is the oldest type of VPN protocol, having been used during the days of the first operating systems. The basic nature of PPTP means that you can set it up easily. However, its main disadvantage is that it is not as secure as the other new protocols. Therefore, many VPN services are abandoning it for the more safe and new forms of protocols.


SSTP in full is Secure Socket Tunnelling Protocol. One of the defining features of SSTP is that it is excellent on devices that run on the Windows operating system. Also, many VPN services use this protocol because it is relatively effective in protecting the traffic of clients. You can, therefore, rely on this protocol to bypass many types of firewalls that some websites use to restrict people who can access their content.


One of the most important features of OpenVPN is that it is a result of an open source project. Developers can access its code and continually suggest improvements for the protocol to perform better. As a result, many people find OpenVPN one of the most secure and reliable VPN protocols that you can use.

In conclusion, these are some of the most common VPN protocols that you can use. Your choice depends on the level of security that you need and the ease with which you can set up the specific protocols. Whereas some protocols are highly secure, others are prone to surveillance.
