NordLynx: NordVPN implements The Wireguard ® Protocol in all applications

NordVPN has introduced a new technology that allows you to increase the speed of the Internet significantly. It is called NordLynx and is already available on all platforms. What does this product offer? Read in this article!

What is the NordLynx Protocol based on?

NordLynx is a combination of several technologies that provide high speed on the one hand and security on the other. So, to create it, NordVPN used the WireGuard Protocol and its own development called Network Address Translation. What are they and why were they chosen?

WireGuard: the fastest Protocol

NordLynx technology was developed on the basis of the secure WireGuard Protocol, created as an alternative to the OpenVPN and IPSec protocols. The main advantage of WireGuard was its speed. Unlike its competitors, this Protocol consists of only 4,000 lines of code (this is 100 times less than the alternative protocols). They are read and checked much easier and faster. However, WireGuard also has disadvantages.

The main problem with WireGuard is the lack of security it can provide. Since this Protocol does not dynamically assign IP addresses to everyone who connects to the server, it must store at least some of the user data. This feature puts personal information at risk.

NAT: a new security system

In addition to WireGuard, NordLynx is based on a dual NAT (Network Address Translation) system. This technology was developed by NordVPN in order to avoid storing user identification data on the server. It was intended to compensate for WireGuard’s security shortcomings.

The dual NAT system works as follows. It creates two personal interfaces on the Network for each user. The first assigns the same IP address to everyone who connects to the server. After installing a secure VPN tunnel, the second interface with the dynamic NAT system is activated. Dynamic local IP addresses are assigned to users only until the end of the session, which means that identification data is not stored on the server.

In other words, only the IP address of the server that all users access is known in advance. Then each person is assigned a personal identification number, which is valid only from the moment of the request until the end of the visit. The next time the user connects to the server, he will be assigned a new number. This means that session data is not stored, so it can’t be compromised.

Is NordLynx really the fastest VPN Protocol?

To test the capabilities of NordLynx, NordVPN has conducted 256886 speed-tests. The research was based on such scientific methodologies as the Kolmogorov-Smirnov test, the Mann-Whitney U-test, and others. They were used to compare the speed of various VPN protocols.

In addition, the tests were based on the 4 most popular VPN usage scenarios:
– The user connects to the nearest VPN server, and the server with the necessary content is located as close as possible from it.
– The user connects to a VPN server abroad, and the server with the necessary content is located as close as possible from the first one.
– The user connects to the nearest VPN server, but the server with the necessary content is far away from it.
– The user connects to a VPN server abroad, and the server with the necessary content is also far away from it.

During testing, NordVPN concluded that NordLynx is superior to its competitors in most scenarios. For example, it was faster than popular protocols such as IKEv2 and OpenVPN. These results allowed us to talk about NordLynx as the fastest Protocol!

NordLynx applications: where can I use the Protocol?

NordLynx was launched in an application for the Linux operating system. However, it is now available not only to its users but also on Windows, Andriod, iOS and macOS. Of course, the new Protocol will only appear in the latest version of apps.

How to activate NordLynx on your device

NordVPN users are configured to automatically select the Protocol. If you did not cancel this option, you will connect to OpenVPN. In the future, this Protocol may be changed to NordLynx, but in the meantime, you will have to choose it by yourself. If you already have a NordVPN app, you can activate NordLynx by following these steps:
1. Update the app version if you haven’t already.

2. Open settings.

3. Mark the NordLynx Protocol instead of automatically selecting it.

Our Conclusion: NordLynx for more speed

The new Protocol from NordVPN is worth attention. The product looks promising and can become an alternative to existing VPN technologies. At least, it’s worth trying it out yourself to make sure that it is both fast and its safe.
