Is WireGuard a good VPN protocol?

WireGuard VPN protocol was created by the same guys that wrote libreswan.

It runs on the Linux kernel, which means it should be compatible with every OS and device that runs Linux. The protocol is very fast, and there are no known issues or issues with it. It can also use UDP and TCP as well, so you can always use it in a TCP-only environment or an UDP-only environment. It has several security features, such as forward secrecy and secure NAT, that enable it to encrypt your connection while not running in a stateful way.

In this article, we'll take a look at WireGuard features, what they are, how to configure them on your router, and what benefits they bring. We'll also briefly review the current status of WireGuard network connections and its future development.

What are the WireGuard features? The main features of WireGuard protocol include: Security: encryption. Encryption of the WireGuard protocols, which can be configured through different ways, such as setting up a static private key, generating a dynamic key, using hardware support, etc. Encryption of the traffic between the devices that use it as a part of their setup. Encryption of the traffic between two parties in case they are connected to the network through NAT (Network Address Translation). Encryption of the traffic during NAT is based on the idea that the public IP address of the WireGuard node changes during the NAT process. This way, the IP address of the other party is never exposed in the clear on the network. To do so, the NAT solution must know what kind of NAT setup is being used and how it is changing.

A NAT solution that knows how it works and can change the IP address of the other side to its assigned one during the NAT process enables the protection from various attacks. For example, if the NAT system is vulnerable to DNS rebinding, then the IP address of the other side might change and you'd get rerouted to some malicious domain.

To enable these features, WireGuard uses the cryptographic features in the kernel, such as crypto APIs, etc. It does not require any extra drivers or software. It has an open source implementation, which was released in March 2025. The implementation is available in the Linux kernel tree in the /drivers/net/wireguard subdirectory.

Which VPNs support WireGuard?

Best VPN for WireGuard

The WireGuard Project's founder and leader, Eric Schmidt, called it one of the few features of the software "so fundamentally, profoundly powerful that it should probably be included" in the network protocol.

That's what the WireGuard project and networking tools team says on a website, while Google itself made a strong appeal for people to try and use it in real products before the network protocol becomes a standard. Google's appeal for using WireGuard could mean that the network protocol gains more attention than it might otherwise get. One such network protocol that became a standard after its open sourcing was IPsec. This is the security protocol that is used by various VPN protocols, too, but WireGuard's approach is different. Rather than trying to make IPSec work as well as VPNs already do, the WireGuard team have put their effort into developing a new IPsec protocol that can be tunneled.

IPsec is often considered to be the old-fashioned security protocol for use with wired networks, while VPNs are seen as the best option for use with the Internet. One reason is that IPsec can be difficult to implement if the users are not already experts with how to set up and use it. The other is that if the Internet of Things devices connected to an enterprise or service providers network had some way of communicating their own individual identity (like EPC generation and management), they could become subject to eavesdropping - because it's possible to capture the traffic without encryption if some sort of message is sent which reveals that this is where messages from this device are coming from, for instance.

This is another reason why many people are looking to use IPsec for something more like a traditional VPN connection between computers than the connection which can also be made with WireGuard and even other approaches that aren't IPsec-related like the new Teredo tunneling. VPNs don't get the same widespread attention for some of the reasons shown in the article, for example. There can be questions about who would be responsible for paying for the connection fees involved, or who would pay for connections out of their limited pool of monthly data - or, for example, they can be limited in how much data they can use when connected to particular services and may have to subscribe to access them.

Does Surfshark work with WireGuard?

Surfshark is the only VPN that offers WireGuard integration, including native Windows support, so you can securely connect to WireGuard-protected networks.

We've put a lot of effort into making Surfshark compatible with WireGuard, including automatic connection setup, a redesigned interface and an improved web site. If you have a WireGuard-protected network and you want to use Surfshark, we recommend that you try it out. As you can see, we have even added a small 'WireGuard' icon to our interface. Just tap it to connect to a WireGuard-protected network or 'unlock' your VPN.

What's the difference between a VPN and a proxy? The two most common terms for this kind of software are 'virtual private network' (VPN) and 'proxy'. A VPN creates a secure tunnel that allows you to send and receive data securely over the internet. A VPN encrypts your internet traffic, and it might also allow you to use an encrypted connection (such as HTTPS) instead of a normal web browser.

A proxy is not a VPN. It acts as a middleman that relays requests from one machine to another. If you're using a web browser, it's usually called a 'web proxy' or a 'privacy protection' feature.

Surfshark uses both VPN and proxy technologies. When you're on a VPN, your internet traffic will be sent through the encrypted VPN tunnel. You won't know what's being sent to the internet. When you're connected to a proxy server, your requests will be relayed to the real destination.

How does Surfshark work? Surfshark works by taking advantage of your operating system's VPN system to provide secure network access. If you're using Windows, Surfshark works by setting up a secure connection to a VPN server. If you're using Mac OS X, Surfshark works by taking advantage of your operating system's VPN system to provide secure network access. If you're using Linux, Surfshark works by taking advantage of your operating system's VPN system to provide secure network access. If you don't have a VPN server installed, you can also use Surfshark as a proxy server. Can I use Surfshark on my Android or iOS device?

Is IKEv2 better than WireGuard?

One of my clients was trying to decide whether they should deploy a WG cluster using OpenVPN with IKEv2 or using IKEv1-IPSec.

After reading IKEv2 and IPsec are not that different, and going through the differences in the protocol spec and its weaknesses and weaknesses, I decided to write this blog article and add more details to what I believe are the advantages and disadvantages of IKEv2. It should be clear by now that I am not a network engineer or expert, and that you should consult a qualified professional when making any decisions regarding network connectivity. So please, if you have issues or problems following this article, then it is your fault, not mine. That said, here's my attempt to answer the question: What is better? I'll also address how much of an improvement IKEv2 would be in a given scenario compared to WireGuard. And, hopefully, it will also provide some food for thought for the people at the OpenVPN development team!

What are the advantages of IKEv2? If IKEv2 looks interesting to you, it means either you don't know much about it or you already have a good understanding. I recommend reading the linked articles first to grasp what I mean by the phrase IKEv2 is different than VPN tunneling. It should become pretty clear as you keep reading.

IKEv2 is a major advance in protocols designed to encrypt end-to-end traffic. For VPNs, there have been many competing standards, including IPSec, openvpn and even SSL VPN. To the best of my knowledge, no one ever released another VPN product until IKEv2, which is why it will always be referred to by some as the first VPN standard. It is the first time the protocol defined a secure mechanism to negotiate and set up a trusted connection between a client and server. We can call this security mechanism an algorithm, but it does have a technical name Diffie-Hellman key exchange.

Diffie-Hellman key exchange is a common property of any encryption algorithm that uses a secret value to share information in a secure way. Let's imagine that Alice wants to talk securely with Bob.
