What is a Wireguard VPN? 

The favorite encryption protocol for enterprises, Perimeter 81’s Wireguard VPN results in faster connections, lower latency and superior security performance.

What is WireGuard?

WireGuard VPNs are the same virtual private networking solutions that many already know and use, but they run on a different encryption protocol called WireGuard, as opposed to alternatives such as OpenVPN, IPSec and others.

WireGuard – and encryption in general – is important for companies small and large, as they allow employees to access resources from anywhere in the world while their connection remains secure.

Resources include any tools, software, applications or even local environments where work gets done – servers for storage, third-party applications, and even cloud SaaS products.

Traffic between remote users in the company – often on unsecured devices or Wi-Fi networks – and these important resources remains private, and encrypted, when IT managers enforce access through the WireGuard protocol.

The special element of WireGuard that has so convinced IT professionals to switch over is its smaller codebase.

At just 4,000 lines it is extremely easy to implement and audit for security, and does its job faster and more efficiently – putting less strain on the network while achieving the best security that encryption can offer.

WireGuard vs OpenVPN: Which Wins?

When comparing OpenVPN and WireGuard, it’s important to consider the strength of encryption but also speed, and flexibility in terms of how easily it can be integrated into different networks. 

OpenVPN

OpenVPN is an open source protocol that was invented in 2001, and despite its age most encryption tools support it, and so it has become the most popular of all VPN alternatives on the market.

It is very flexible and offers a range of supported cryptographic algorithms, which make it easy to integrate almost anywhere.

However, these advantages also come with a cost. OpenVPN’s flexibility also comes with an enormous codebase amounting to hundreds of thousands of lines of code, so it can be incredibly difficult to audit, and to ensure that the attack surface is adequately protected.

WireGuard

WireGuard, on the other hand, boasts a lightweight codebase of just 4,000 lines, making it extraordinarily auditable. Its slimmer range of supported cryptographic algorithms may be limiting in some cases, but this also narrows the attack surface significantly, providing great encryption to all traffic sources.

The primary advantage to a WireGuard VPN, however, is its speed. Enterprises are reporting lower latency and faster upload and download speeds by as much as 40% over alternatives.

This simple idea finally removes the compromise between work productivity and security for companies switching their Business VPNs to WireGuard. As of today, WireGuard is the best OpenVPN alternative

How Does a WireGuard VPN Work?

WireGuard VPN providers offer a simple application that is installed on personal or company devices, that grant employees of the company secure access to crucial resources like cloud-based SaaS tools, local data storage, and other solutions.

The employee simply needs to ensure that he or she is connected to the WireGuard client before trying to access company resources (like logging into Salesforce), otherwise they will not succeed.

The WireGuard VPN server establishes a tunnel between the employee and the corporate network upon successful login, so that afterward any resource within the network can be reached privately, without anyone being able to eavesdrop on the employee’s connection.

The WireGuard VPN tunnel uses WireGuard protocol, which is a cryptographically secure approach to managing public keys, but it can support different algorithms including ChaCha20 for symmetric encryption, Poly1305 for authentication, BLAKE2s for hashing, UDP as the TLP and HKDF for key creation.

It’s also important to know that WireGuard uses public key encryption rather than certificate management. This is part of its lesser complexity and a central reason why it reduces the network’s attack surface, leaving hackers with few options for how to breach inside.

 Why Should My Company Use a WireGuard VPN?

It’s almost impossible to come across an enterprise level company that doesn’t have both local and cloud-based solutions in its network, and this idea alone makes it necessary to have an agile cloud friendly WireGuard VPN.

With over 96% of companies having moved their infrastructure to the cloud – things like file storage, administration, data analysis, finance and more – it’s crucial that protective measures allow smooth yet inclusive access to these environments.

Moreover, as employees increasingly use their own devices for work, WireGuard VPN is even more relevant for its thorough coverage of diverse endpoints.

Using an alternative hardware-based VPN or a VPN that was introduced decades ago means incompatibility and a loss of efficiency across the organization.

Though solutions like OpenVPN or IPSec VPNs provide encryption, they are not agile enough to handle multiple connections consistently without crashing tunnels or slow speeds, in many cases.

There’s also the idea that WireGuard VPNs are often packaged in the most cutting-edge network and security solutions, which include the ability for IT teams to segment traffic and restrict access based on user identifiers.

WireGuard providers can therefore provide a more holistic approach on top of mere encryption, which stops insider attacks in their tracks.

Beyond the threat of insider attacks or accidental exposure lies the idea that employees’ daily security hygiene and habits are themselves a risk.

Remote work is more popular than ever, and employees are enjoying BYOD – Bring Your Own Device – rules and work from home in greater numbers. Employers’ networks are taking a new shape during this remote work era, and access is occurring from the edge rather than within the traditional perimeter.

Using an older VPN, hardware solutions, or less comprehensive and cloud-native security solutions is negligent under these conditions. Adept solutions include WireGuard by default, as it more capably encourages the user-centric security approach necessary to keep modern networks safe. 

All this is to say that WireGuard VPNs and WireGuard providers – solutions that include the WireGuard protocol – are safer, faster, but also more cost efficient than others.

 WireGuard VPN Protocol Performances

WireGuard is the VPN Protocol that offers the highest Bandwidth (3.87x higher than OpenVPN) and the Lowest Latency (with a Ping Time that is 3.2x Lower than OpenVPN).

WireGuard FAQs

What is WireGuard? What is a WireGuard VPN?
It helps to think about the alternatives like OpenVPN, IPSec and others. These are all protocols that establish an encrypted tunnel between a person’s computer and a resource that they are connected to, like an application or a server somewhere. This keeps the data being transferred between them private.
How do I setup WireGuard?
Setting up a WireGuard application is simple. All you need to do is download it, launch it, and then point it at the network you want to connect to. This involves typing in the IP address, port number and other details and then activating the client.
What’s better: IPSec vs WireGuard?
It all depends on the network environment you are using. There are many reports that WireGuard offers the same level of encryption while making connections faster, but some enterprises may prefer IPSec due to the type of cryptography algorithms it supports.
Is WireGuard free?
WireGuard is originally open source and can be used for free, absolutely. There are many free VPNs that support WireGuard, and it is also included by default in the Linux kernel, so those who are adept at programming can establish these types of encrypted connections simply by typing in the command line. WireGuard is also supported by subscription-based security products.
How do I use WireGuard?
Using WireGuard is as simple as selecting it as the active encryption protocol in your VPN client. From then on all connections will be tunneled using WireGuard rather than alternative protocols.
Is WireGuard safe to use? Is WireGuard secure?
Though it is relatively new on the scene, WireGuard’s tiny codebase has been thoroughly tested and audited, and it’s inclusion on the Linux kernel is an enormous vote of confidence in its safety. There have been no reports of any WireGuard exploits, but it’s always recommended to test and read before integrating it into your network.
How does WireGuard work?
WireGuard works by automatically routing a user’s traffic and through a WireGuard server elsewhere, masking the original IP of the user and ensuring that snoopers can’t actually read any of the data being transmitted – even if they get their hands on it.
