All You Need To Know About The New WireGuard Protocol

By  | 


In today’s digitalized world, we use the internet to take care of almost all our everyday needs. Ordering food, finding a cab, shopping online – these are just a few of the things we do online. 

All these services, however, require the user to disclose private information, such as their name, address, as well as card number, and other banking details. If this information falls into the wrong hands, it can result in some serious issues for the user. This is why we need to be very careful and protect our online privacy, no matter if we use a public or private connection. 

A VPN (Virtual private network) is one of the best methods to encrypt your internet connection and keep your private data protected, but how do you choose a reliable one? 

Among the most important factors to consider when choosing a VPN is the encryption protocol, which ensures the reliability and privacy of your network. 

The newest and most promising open-source VPN protocol is WireGuard, which we will be discussing below so that you can get a better understanding of the matter. 


What is WireGuard?

WireGuard was created in 2018 and is a new open-source VPN protocol. Its goal is to provide easier, faster, and more secure online experiences for users and has been praised by many in the industry. The protocol was mainly developed with Linux users in mind but works just as well on other operating systems, such as Windows or Android. 

The main purpose of WireGuard, just as any other VPN protocol, is to create a secure connection between the VPN app and the VPN server. This is called a VPN tunnel. It supports a symmetric encryption key, as well as an optional pre-shared key. 

Compared to other VPN protocols, when the VPN server uses WireGuard, it does not respond to the user if the user has not been authorized. This happens in order to reduce the risk of DoS attacks, which have been very popular among hackers.


Advantages of choosing a WireGuard VPN

As to not get confused: WireGuard itself is not a VPN, but a VPN protocol. So, a WireGuard VPN is a provider that offers, among its services, WireGuard VPN connections. 

There are many VPN providers that support WireGuard, including popular names such as ExpressVPN and Nord VPN, and that’s because of the multitude of advantages it brings. Among these benefits are:


WireGuard had to pass some severe audits, and it did so with grace. Instead of using cryptographic agility, which is known to cause some issues, it uses cryptographic algorithms, ensuring no one can misconfigure the code and leaves users at risk. And, if at one point, one of these algorithms becomes vulnerable, the situation can be fixed with the release of a new protocol version. 


Compared to other protocols, such as OpenVPN, WireGuard is much more reliable and faster. Naturally, when you use a VPN, you are bound to lose some of your download speed, but some VPN protocols can make the user feel as if they were back to the 2000s again. WireGuard proved to be faster than its competitors in 58.8% of tests. The average speed loss revolved around 19%, compared to the 20.6% and 58.1% results from its competitors.

Ease of use

Especially if you use Linux, WireGuard VPNs are going to be very easy to install and use, because it used advanced public keys to make things more straightforward. It supports a variety of devices, including routers, to provide a stellar user experience. 


How do I know I chose the right VPN?

WireGuard provides plenty of advantages, which is why many VPN providers have started integrating it into their products. But with so many options on the market, how do you know which one to choose? Here are some key aspects to consider:

Your needs

What you need from a VPN is going to dictate the type of service you choose. For example, if you often use public Wi-Fi networks and want a VPN to protect your data, then you need one that provides high security, whereas if you want a VPN for your home, a router-based VPN is a much better option

VPN characteristics

Most VPN providers prioritize one of their features over the others. This means some providers offer great security and less speed, while others are known for reliability and bypassing geo-restrictions. For example, if you are someone that values their privacy and security, you should look for a VPN that has secure encryption protocols, such as those using WireGuard. 

User experience

VPNs shouldn’t be complicated to use, but some do require a little bit more knowledge to set up. Make sure you choose a VPN that has a user-friendly platform or provides reliable customer service options so that you can call and require assistance if needed.
