Various security protocols that would provide the appropriate and effective VPN services are supported by many VPN providers. When it come to meeting the needs of each client, the effectiveness and security levels of each protocol listed below differ from one another.

Let’s look at the various security protocols more closely and try to examine their advantages and disadvantages so that you can determine which security protocol meets your needs best.


  1. OpenVPN (recommended by Best VPN Canada).


OpenVPN is an improved open source software that provides a secure VPN service that is reliable. On both UDP and TCP ports, its versatile protocol function can be used. By using AES-256-CBC with a 2048-bit DH key, its encryption ciphers and algorithms support, guarantee and secure data protection. Apart from the fact that many

Apart from the fact that many VPN services use OpenVPN for applications, we recommend this VPN service software due to its efficient advanced features of data security, all of which ensure data privacy.


  1. Protocol for Secure Socket Tunneling (for Windows Family OS users).


For Windows Family OS users, the Secure Socket Tunneling Protocol is usually suggested because this VPN security mechanism was developed for Windows and its users. SSTP first was presented in Windows Vista Service Pack 1. by Microsoft.

Windows users find SSTP far more safe and stable than all other protocols with its inclusion into Windows OS. The latest update features the use of AES encryption, which protects SSTP from independent audits. However, this means that SSTP is used at your own risk, as the checks depend on the users.


  1. Protocol of point-to-point tunneling (recommended for advanced users only, not for general use).


One of the initial and earliest protocols ever generated is PPTP. It is easy and straightforward to use. It works okay on several versions of Windows, such as Windows 95 and Windows 7, but PPTP does not work well enough to meet the needs of users, causing other encryption protocols to come into existence.

When it comes to security, PPTP does not provide users with the expected level of protection. It is only recommended to use it in cases where legacy support is required and security is not available.


  1. L2TP / IPSec (recommended for advanced users only, not for majority of users)


L2TP / IPSec certainly can’t compete if you compare it to newer encryption protocols. But one of the best was L2TP / IPSec in the early birth of protocols. L2TP/IPSec is a 2-layer tunnel protocol in IPSec and is primarily used, like PPTP, in cases where security is not important or at least not a priority.

As it is one of the earliest inventions, there are tons of features that other protocols have that L2TP/IPSec does not. On the other hand, there are also functions that only L2TP/IPSec can perform, which is one reason why users even use it so far.

Many instances have occurred in which clients have old hardware that can only customize old protocols. In countries where only old procedures like L2TP/IPSec can pierce government and ISP encryption, there are several cases where customers are located.


The IKEv1 protocol that supports a wide range of devices and operating systems is used by L2TP / IPSec. L2TP / IPSec has limitations, however. To ensure an official match between both the client’s data centres and the VPN, it needs organisational structure.


I can be hard for users to manage certificates. This protocol allows for a faster connection to a VPN. In fact, it is mainly used in cases where there is not enough time for an elaborate setup. Moreover, we recommend using this protocol only as a last resort and when needed.


  1. IKEv2 / IPSec (highly recommended)


Speaking of the IKEv1 protocol: This next encryption protocol is highly recommended on this list. As mentioned, IKEv1 is a very important feature that can solve problems on many devices, but it has limitations. IKEv2 / IPSec has arguably none.


The completely new, updated version of IKEv1 is IKEv2/IPsec. As the newest version, compared to the previous, IKEv2 offers many advancements and functionalities. With its inbuilt NAT transversal, its tunnel convergence is much speedier.


The limitation of IKEv1 includes the overhead of authentication procedures when matching servers between the VPN and clients. IKEv2, the updated protocol, does not have this limitation.


It no longer requires onerous authentication procedures. Server identity authentication is identified by digital certificates for VPN servers and username, code or password authentication for clients.


This greatly reduces the risk of brute force or man-in-the-middle attacks, the intrusion between private communications. IKEv2 / IPSec stability and speed are incredibly consistent and reliable. The benefits of this protocol are simply innumerable.

This list of VPN protocols is a reference you can use when switching from different native defaults. There are almost countless different protocols, and we believe you have every right to make your own choice.
