6 common VPN protocols

In this era, VPNs are as important as oxygen. It becomes challenging to survive in the internet world without a VPN. But, while using a 

It is essential to understand the VPN protocols that come along. You must be wondering what kind of protocols are these? Here is an option of thepirateproxybay that can answer all your questions.

VPN protocols are responsible for deciding how a particular data can be directed through a specific connection. All such protocols are based on various specifications that come with certain advantages, such as few VPN protocols consider that data is more important than speed. In contrast, others concentrate on encrypting or hiding data bundles for the purpose of security.

These VPN protocols are essential, which is why here we have lined up six common VPN protocols as a guide for you;


 PPTP or Point-to-Point Tunneling Protocol is known to be one ancient VPN protocol in the world. The team of Microsoft introduced it in the mid of 1990s. PPTP was combined for Windows 95 and was mainly developed for dial-up connections.

However, due to the technological advancement, its primary encryption featured distorted, affecting its security. Although it doesn’t offer advanced security features like modern protocols available today, it is suitable for users who do not prefer dense encryption.


This VPN protocol is an open-source one; this indicates that users can examine the source code to check if there are any weaknesses in the system. OpenVPN is famous for being the most essential and secure VPN protocol.

It enables the users to secure the data through unbreakable key encryption called AES-256 bit along with 2048-bit RSA authentication and identification. Not only this, but it also offers a jumbled algorithm of 160-bit SHA1. Moreover, OpenVPN is accessible for nearly all Linux, Windows, Android, Mac, etc. Blackberry and Windows Phone can also use it.

However, OpenVPN has been criticized for low speeds; with constant upgrades and implementation, its performance has been improved, features like privacy and security have been enhanced.


SSTP, also known as Secure Socket Tunneling Protocol, is the next essential VPN protocol. One significant benefit of this protocol is that it’s wholly aligned and combined with all Microsoft operating systems. This indicates that SSTP can be used with both Winlogon and a smart chip for enhanced security.

Moreover, for authentication purposes, SSTP utilizes 2048-bit SSL/TLS certification, and along with it, 256-bit SSL keys are used for encrypting, which makes the entire SSTP secure for use. Since Microsoft developed SSTP, no one can thoroughly audit the primary code. Lastly, it supports BSD systems, Windows, and Linux. In contrast, some third-party clients support macOS, Android, and iOS.


L2TP or Layer 2 Tunnel Protocol is a successor of PPTP, which Microsoft introduced, whereas Cisco established L2F. But L2TP doesn’t offer any privacy or encryption as it’s generally said that when opting for L2TP, a security protocol known as IPsec is used together, which makes it the safest VPN connection for users.

This VPN protocol has no obvious susceptibilities and has AES-256-bit encryption. However, L2TP/IPSec has some minor issues, like the protocol uses UDP on port 500, due to which it’s easy to spot traffic and block it.


IKEv2 is also a VPN protocol that Cisco and Microsoft developed. It is primarily a tunneling protocol that offers a secure session, and it is usually paired with IPSec to provide features like authentication and encryption. IKEv2 isn’t famous like remaining VPN protocols, traditionally found in several mobile solutions. This is mainly due to its ability to reconnect when the internet connection is lost, and any network switch occurs.

It operates as a proprietary protocol, providing support for Blackberry, Ios, and Windows devices, while for Android, Linux implementations are sourced through third-party applications.


Wireguard is new in the list of VPN protocols. It lies in the category of open-source VPNs and has a relatively simple codebase compared to other VPNs. Moreover, Wireguard services are accessible to set up, unlike OpenVPN, and it also offers a wide range of encryption services. It is one suitable option for all types of portable devices due to the combination of primitives that it provides, along with the minor code base.

Therefore these are some of the VPN protocols that are commonly used. It is better to opt for a VPN provider that allows you to choose the protocol you want. Moreover, it’s advisable to opt for paid services instead of a free one as when you opt for a free you usually have no idea what may enter your device, and your data might be compromised.
