WireGuard VPN is open source and free software that implements encrypted VPN. Ease of use, high speed and low attack surface are the main goals for its creation. It passes traffic over User Datagram Protocol (UDP) which uses no handshake protocol. WireGuard has been adopted by many VPNs since it is designed to outperform common tunneling protocols such as IPsec and OpenVPN. Although it was initially released for Linux, it is now cross-platform and supports Windows, macOS, BSD, iOS and Android. To get a secure, easy-to-use and simple VPN solution, Wireguard shines as the best option. It is currently under extensive development but has been deployed. It resides inside the Linux kernel which results in high speed for secure networking.
In this article, you will learn everything you need to know about the WireGuard VPN protocol. To start having your own private online space and to test different VPNs, Linux VPS is a good choice. Say hello to 24/7 support.
What is the Wireguard VPN protocol?
A VPN protocol enables your computer or phone to communicate with a VPN server. To explain further, a VPN creates an encrypted tunnel between you and the Internet to keep your data private. So, to secure all your internet traffic, you need to use a VPN protocol. Initially, WireGuard was released for the Linux kernel, a core component of the Linux operating system known for security and speed. Wireguard is a VPN protocol that is renowned as a fast, modern and secure way to connect to a VPN server. It is able to run on your device using advanced cryptography.
If you need to know some basics or refresh your mind, you can read about different VPN protocols. But come back soon.
Is Wireguard replacing other VPN protocols?
Vulnerability is a very important option when comparing VPN protocols. Compared to alternatives, Wireguard allows professionals to find potential vulnerabilities and bugs more quickly. It uses less code, so hackers will have access to a smaller “attack surface” that makes exploits more difficult. OpenVPN is a well-known protocol that has helped WireGuard become more popular. Because after every comparison, WireGuard wins the fast, easy-to-use and secure protocol competition. Despite Wireguard’s brilliant features, it is still not supported by all VPN services, which slows down the replacement process. In the next section, you will review all its important benefits.
What are the Wireguard Advantages?
Here are the outstanding advantages of Wireguard which we say makes this tunnel one of the best VPN solutions in the industry. Wireguard’s important role in cyber security is undeniable. It is fast and secure at the same time which is valuable in the world of VPN protocols.
Light code base
While Strong Swan/IPsec has 400,000 and OpenVPN/OpenSSL 600,000 lines of code, WireGuard only has 4000 lines of code. This is a remarkable feature, at least compared to open-source VPN protocols. Wireguard’s small codebase creates a minimal attack surface that can be exploited by cyber criminals.
Ease of deployment
Is SSH as easy to configure and deploy? So, you are talking about wireguard. IT professionals can easily set up WireGuard as it is no more difficult than configuring SSH. Its client and server parts are easy to install. Like mosh, it’s capable of roaming between IP addresses. Once you choose WireGuard, you don’t have to manage connections, worry about state, or manage daemons.
Streamline design
Unlike WireGuard, some VPN protocols that aren’t quite as fast use handshake authentication between clients. But WireGuard is able to quickly connect and reconnect while roaming between networks. Its design helps speed up VPN connections. Other VPN protocols sometimes feel fragile or clunky.
Security
WireGuard is highly secure as it uses the latest modern cryptography with secure defaults. However, users need not worry about speed or usability as they are provided at the same time.
Tip: If you want to bypass all security boundaries and protect your personal information and browsing, there is a complete solution. Using Mikrotik as a private VPN server. A dedicated IP and trusted tunnel can be easily set up with a Mikrotik VPN server.
Speed
You can rely on WireGuard’s speed because it uses fast cryptography codes. It’s even faster than Userspace VPN because its low-level components reside within the Linux kernel.
Open source code
Being open-source helps VPNs ensure that features don’t violate user privacy and security. And a large VPN community ready to fix any problems, audit the code and improve its design.
Easy to set up
It is very easy to use and easy to set up. Users are able to connect through their VPN application with the click of a button.
WireGuard Disadvantages
The good news is that Wireguard doesn’t have any major weaknesses, but despite all the advantages mentioned, no VPN protocol is perfect. Let’s see what are the advantages of this young protocol.
Support issues
WireGuard does not work without additional software. (Only works on some Linux distros). So, you may have to change your mind about choosing Wireguard if you prefer to use a VPN on a device where you cannot install apps because the recommended client apps are not enough.
Privacy
As you know, Wireguard is fast. The UDP transport layer helps increase the speed of a VPN connection. But this can be a problem because using a VPN can no longer be secret. Therefore, it is not possible to bypass the firewall to access the content you consider. Don’t use WireGuard if your government, ISP, or employer sees you using a VPN.
How does WireGuard Protocol work?
As we mentioned, WireGuard uses advanced cryptography and network code to create an encrypted tunnel. If you switch from mobile data to Wi-Fi (IP change), the VPN’s clever tricks won’t disconnect the connection. WireGuard’s speed and security depend on its unique design and encryption method.
4 VPNs support WireGuard
It’s a fact that WireGuard is not yet supported by all VPN services, but some commercial VPN providers are quickly starting to use it.
- NordVPN: A VPN that was the first of the “major” VPNs to adopt WireGuard. They achieved this by adapting the free software WireGuard and creating their own protocol called NordLynx. Consequently, NordVPN is the top WireGuard VPN.
- Surfshark: A well-known VPN that offers its services with advanced security features. Wireguard protocol is one of them. Instead of static IP addresses, Surfshark makes its WireGuard users dynamic. As a result, your privacy online is protected.
- IPVanish: A flexible VPN provider that recently added WireGuard tunneling techniques to its list of features This is an essential improvement to IPVanish’s overall offering.
- Mullvad: This VPN has sponsored Wireguard since the beginning as an early financial backer of the project. Wireguard is the preferred way to use Mullvad for now.
Usually, you can create your own VPN server and set it up to support Wireguard out of the box. Then, you’ll be faced with fewer configuration options to tweak for maximum security. First, you need to know the best OSes to build a VPN server.
Comparing Wireguard with the two best VPN protocols
Compared to previous standards, WireGuard is very fast and easy to configure. Wireguard connects quickly. Alternatives like IPsec and OpenVPN had large, inadequately tested codebases that could hide various security flaws. All this is made easier with Wireguard, which also provides a superior end result.
In this part, we are going to explain how Wireguard differs from its alternatives; OpenVPN and IPSec/IKEv2.
WireGuard vs. OpenVPN
Currently, OpenVPN is the most widely used VPN protocol. Like WireGuard, OpenVPN is open source, has minimal security holes, and requires frequent additional files on most devices. But modern computer CPUs were not considered while designing OpenVPN. Due to its contemporary approach, WireGuard has many performance and security advantages over existing VPN protocols. In one test, WireGuard beat OpenVPN by 15% in terms of raw speed. Wireguard was 56% faster while OpenVPN was limited to it is slow TCP mode. While the best-case comparison doesn’t show a dramatic improvement, WireGuard’s performance boost will be noticeable, especially when downloading large files.
Both OpenVPN and WireGuard are open-source, have few security flaws, and require additional configuration files to install on most devices. The difference is that WireGuard uses a much more efficient and much more sophisticated cryptographic library. Additionally, the WireGuard protocol has a significantly lower impact on battery life than OpenVPN.
Wireguard vs. IPSec/IKEv2
Business VPNs often employ IKEv2/IPsec, which offers several encryption techniques. Although IKEv2/IPsec is a more flexible protocol than Wireguard, IKEv2’s encryption techniques are more dated and, in general, less efficient. From the point of view of faster primitive cryptography and built into the Linux kernel, WireGuard wins the competition. It’s also consistently faster. IPsec’s design is heavier and heavier, and it is more prone to hacking because it has more lines of code than other traditional VPN protocols. In contrast, WireGuard is faster, more secure, and clearly made for computers in the current era.
IKEv2 and WireGuard differ in that the former will be supported by default on most devices. You need to install additional files to use WireGuard. But it has an advantage over more recent cryptography libraries. IKEv2 will be faster in most use cases despite not requiring a lot of CPU power to protect against attacks.
Still, IPsec has its advantages. WireGuard won’t work if your network encryption needs to use legacy encryption techniques. Depending on your network requirements, IPsec and its wide selection of encryption techniques may be more appropriate.
Setup the WireGuard VPN protocol step by step
If you don’t want to use a commercial VPN package, you can install WireGuard on your own VPN server. For the average user, setting up a private VPN server is a challenging operation, but WireGuard makes it remarkably easy. Depending on your system, there are several ways to set up a WireGuard server So for comprehensive instructions, visit the WireGuard website.
However, setting up WireGuard VPN requires you to go through 9 main steps.
- First, you need to set up a VPN connection on your computer.
- Download and install WireGuard on your VPN.
