Many VPN providers support different security protocols which can provide the necessary and efficient VPN services. The efficiency and security levels of each protocol listed below vary from one another, so does the needs of every customer.
Let’s take more than a closer look at the different security protocols and try to scrutinize their strengths and weaknesses, so you will be able to identify which security protocol agrees with your needs better.
1. OpenVPN (recommended by Best VPN Canada)
OpenVPN is an advanced open source software that provides reliable, secure VPN service. Its versatile protocol feature can be both used on UDP and TCP ports. Its encryption ciphers and algorithms support, ensure, and secure protection of data by using AES-256-CBC with DH key by 2048bit. Aside from the fact that many
Aside from the fact that many VPN services use OpenVPN for applications, we recommend this VPN service software because of its efficient, advanced features of data security, which all ensures data protection.
2. Secure Socket Tunneling Protocol (For Windows family OS users)
Secure Socket Tunneling Protocol is recommended to Windows family OS users mainly because this VPN security protocol is created for Windows and its users. SSTP was first introduced by Microsoft in Windows Vista Service Pack 1.
With its integration with Windows OS, Windows users find SSTP much safer and stabler to use than any other protocols. Its recent update features the use of AES encryption, which makes SSTP protected from any independent audit. This, however, means that SSTP will be used at your own risks as the controls are dependent on the users.
3. Point-to-Point Tunneling Protocol (only recommended for advanced users, not for general use)
PPTP is one of the first and earliest protocols ever created. It is simple and easy to use. It runs well on several Windows versions like Windows 95 and Windows 7. However, PPTP does not work well enough to satisfy users’ needs, which triggers the birth of other encryption protocols.
When it comes to security, PPTP fails to provide the expected levels of protection for users. It is only recommended to be used in cases when legacy support is needed and when security isn’t.
4. L2TP/IPsec (only recommended for advanced users, not for general use)
If you compare it to newer encryption protocols, L2TP/IPsec sure can’t keep up. But in the early birth of protocols, L2TP/IPsec was one of the best. L2TP/IPsec is a protocol with a 2-layered tunnel in the IPsec. Like PPTP, it is mostly used in cases when security isn’t important or, at least, not a priority.
There are tons of features that other protocols have that L2TP/IPsec don’t since it is one of the earliest inventions. On the other hand, there are also features that only L2TP/IPsec can do, which is one reason why users use it even up until now.
There have been a lot of cases where clients own old hardware wherein only old protocols can configure. There are also cases where clients are based in countries where only old protocols like L2TP/IPsec can penetrate governmental and ISP firewalls.
L2TP/IPsec uses the IKEv1 protocol, which supports a variety of devices and operating systems. However, L2TP/IPsec has limitations. It requires authentication procedures to ensure an official match of the client’s and the VPN’s servers.
We understand how troublesome and time-consuming managing certificates is for users. This protocol allows a faster connection to a VPN. In fact, it is largely used in cases when there is not enough time for an elaborate setup. Moreover, we only recommend this protocol to be used as the last resort and when highly necessary.
5. IKEv2/IPsec (Highly Recommended)
Speaking of IKEv1 protocol, this next encryption protocol is the highly recommended one on this list. As said, IKEv1 is a very important feature that helps solve problems on many devices, but it has limitations. IKEv2/IPsec hardly has any.
IKEv2/IPsec is the newer, updated version of IKEv1. As the latest version, IKEv2 has many improvements and features compared to its predecessor. Its tunnel convergence is much quicker with its built-in NAT transversal.
The limitation of IKEv1 includes the hassle of the authentication procedures when matching the servers between the VPN and the clients. IKEv2, being the updated protocol, doesn’t have that limitation.
It doesn’t require troublesome authentication procedures anymore. The authentication of the server identity is identified through digital certificates for the VPN servers, and authenticating username, codes, or passwords for clients.
This greatly diminishes the risks of brute force or man-in-the-middle attack, the intrusion between private communications. IKEv2/IPsec stability and speed are incredibly consistent and reliable. The advantages of this protocol are just countless.
This list of VPN protocols is a reference you can use when shifting from different default native application settings. There are nearly countless different protocols, and we believe you have every right to make your own choice.
