How To Get Started With WireGuard VPN: A Complete Guide for 2024

Virtual Private Networks (VPN) are strong advocates of staying secure online. A VPN creates a safe tunnel your data can pass through without the influence of malicious entities. VPNs use secure and reliable protocols to achieve their primary goal: to move customers’ data from point A to point B safely. A VPN is only as good as the protocol it uses, as protocols determine the reliability, performance, and security of VPNs. 

You are not safe from bad actors if you use a VPN that implements a protocol that is vulnerable to attacks. There are several VPN protocols you can use, such as L2TP, SSTP, PPTP, OpenVPN, IPSec, and IKEv2. These protocols offer a balance between performance and security. Most of these protocols have been around for a while and have served VPN users for many years. WireGuard is the latest VPN protocol as it has only been around for about half a decade. This article looks at the WireGuard protocol and VPNs that support it.

What is WireGuard?

About five years ago, Jason Donenfield started working on what would be the future of VPN protocols. WireGuard is an open-source tunneling protocol that is swift, reliable, and boasts less overhead. Compared to most protocols, its codebase is significantly smaller. With just over 380o lines of code, WireGuard makes the job of auditors less stressful. Its small codebase also reduces the attack surface, making it easier to identify vulnerabilities and fix them. 

WireGuard uses modern protocols such as ChaCha20 for symmetric encryption, Poly1305 for message authentication, Curve25519 for key exchange, Blake2s for hashing, and SipHash24 for hashtable keys. It also has in-built protection against DDoS attacks, replay attacks, and key impersonation. While there are concerns about a couple of privacy issues with WireGuard, VPN service providers implement it with a Double NAT system to fix its privacy setbacks. WireGuard was initially intended for Linux as it works in the Linux kernel, but it now supports Windows, macOS, iOS, and Android. 

How To Use a WireGuard VPN

Some VPN services already use WireGuard as their default protocol because of its benefits. To use WireGuard, you need to choose a VPN service provider that supports it. Let’s take a look at the step-by-step process of using a WireGuard VPN.

1. Get a VPN service that has WireGuard as part of its VPN protocols. You will need to pay for a subscription that you can afford. After this section, we will recommend VPNs you can use that support WireGuard.

2. Download and install the application from the service provider’s website or the application store on your device. Before you download, confirm that the VPN service supports WireGuard on your operating system. 

3. Once you have installed the VPN application, ensure that the default protocol is WireGuard before connecting to a server. Change it if it isn’t.

4. Connect to a server.

Now you can enjoy the swiftness and dependability of the WireGuard protocol. 

Below, we look at VPN services that currently give users the option to use the WireGuard protocol.

ExpressVPN already boasts of being one of the fastest VPNs. While it does not have a WireGuard implementation, its Lightway protocol is as swift and reliable as WireGuard. Some people even believe that it is better than WireGuard. With ExpressVPN, you have access to over 3000 servers in 94 countries. 

In terms of speed, ExpressVPN’s Lightway, like WireGuard, has instant connectivity. Lightway eliminates the need to wait before you connect to a server; once you click the “connect” button, you already have access to the server. The protocol’s small codebase is another reason for its swift connection; it has about a thousand lines of code.

Lightway uses cryptography libraries and protocols such as woflSSL and ChaCha20. Furthermore, ExpressVPN uses AES-256 encryption to protect its users against attacks by bad actors. It also has additional security features such as in-built leak protection, perfect forward secrecy, Tor over VPN, Split Tunneling, and a Kill Switch.

ExpressVPN is available on several operating systems, including Windows, Android, macOS, iOS, and Linux. With rich features and reliable service, it is one of the most expensive VPN services. However, it offers a 30-day money-back guarantee for anyone looking to check out its services.

Pros and Cons of Using WireGuard

While WireGuard delivers fast and secure connections, it also has its issues. Below, we will dive into the benefits and drawbacks of WireGuard.


There are many advantages with the Wireguard protocol:

1. Performance:

WireGuard is one of the fastest VPN protocols. VPNs that use it benefit from its small codebase and high-speed cryptographic primitives. NordVPN’s WireGuard-based protocol, when put under the same conditions as OpenVPN and IPSec, proved to be faster than both protocols. Another reason why it offers better performance is that it works in the Linux kernel. 

2. Ease of Use and Configuration:

WireGuard is easy to configure because it uses public key infrastructure, unlike protocols like OpenVPN that rely on certificates. It is easier to set up and install compared to OpenVPN and IPSec. This is primarily due to its smaller codebase. It is also easy to audit and check for vulnerabilities. 

3. Security:

WireGuard uses modern cryptography protocols that allow it to be secure. Protocols such as ChaCha20, Poly1305, Curve25519, Blake2s, and SipHash24 ensure that your connection is not attractive to hackers. It also has protection against DDoS, key impersonation, and replay attacks. 


Some disadvantages include:

1. Privacy Issues:

While WireGuard has performance, security, and configuration benefits, security researchers have some privacy concerns. WireGuard uses static IP addresses and keeps them on the VPN server until the service provider reboots it. Assigning static IP addresses and storing them on the server means that a bad actor can trace the connection back to you if the server gets compromised. This is why VPN services that support WireGuard implement a Double NAT system to assign dynamic IP addresses and prevent the protocol from storing users’ IP addresses. 

2. Stability:

There have also been concerns about WireGuard’s stability in the past. It is still a relatively new protocol as it just gained mainstream usage in 2020. On Linux, it is very stable, as the WireGuard team released a stable version into the Linux kernel recently. Since Android is Linux-based, the Android version is also stable. There have been issues with WireGuard on the FreeBSD-based operating systems that have made WireGuard unavailable on devices such as pfSense.


WireGuard is not as widely used as OpenVPN. It is open-source but has not gone through the test of time as OpenVPN. However, with more VPNs deciding to use it, WireGuard will be the default protocol for most VPN service providers in the near future. Its speed, reliability, and low overhead will pave the way for it. VPN services that already use it have shown that you can easily solve its minor privacy issue using a Double NAT system. WireGuard is what you should use if you’re looking for a VPN protocol that is quick, secure, dependable, and power-saving.
