The VPN industry is excited about this next generation WireGuard protocol. Its technology is very promising in regards to speed, security, and performance. But, like every new technology, is not yet widely available. The protocol that deals with your privacy and security, needs some time to settle.
There aren’t that many WireGuard VPN providers yet. Extensive real-world testing is necessary before mass adoption. But as the world moves fast, there are already VPNs that support the WireGuard protocol.
Short on time?
Here are the best VPNs that support WireGuard:
- NordVPN – the best VPN with WireGuard (NordLynx) for speeds and security
- Surfshark – WireGuard VPN provider that is excellent for streaming
- Private Internet Access – great for torrenting and port forwarding
- TorGuard – a service with lots of customizations
- AzireVPN – supports WireGuard protocol since 2017
What is WireGuard
WireGuard is a modern VPN protocol that uses state-of-the-art cryptography. It uses the concept of crypto-key routing. It can reach faster speeds, increase security, and be set up easily. WireGuard is a cross-platform protocol that works on all OS. It is considered as one of the most secure solutions to date.
The WireGuard creator, Jason A. Donenfeld, said that the protocol was designed with simplicity in mind. Other VPN protocols like OpenVPN and IPSec were developed more than 20 years ago. They were built with old ideas and understanding about security and cryptography. This resulted in an extremely complex and hard-to-understand codebase.
WireGuard uses fresh, modern, and science-based development techniques. This resulted in a codebase with just around 5000 lines of code.
For comparison, here’s a comparison of other VPN protocols by lines of code. You can get an idea of how straight-forward and easy to understand Wireguard’s code can be.
5 Best VPN Providers that support WireGuard
NordVPN released the WireGuard protocol for its Windows, macOS, Android, and iOS users. It extensively tested the next-generation protocol in regards to security and privacy beforehand.
NordVPN engineered a double NAT system around the WireGuard and called it NordLynx. This technology tackled the IP address logging issue.
This WireGuard VPN provider already offered great speeds and it got even faster. You can easily connect with NordLynx on any of their apps by selecting the option in the settings screen.
Windows App Example, but the same on any other (mobile included): NordVPN has been a secure and audited no-logs provider. It has no IP or DNS leaks and has many features to protect your internet traffic:
- CyberSec – ads and malicious website blocker
- Obfuscated Servers – hides VPN traffic circumvents censorship in restricted countries
- Double-VPN – double encryption with multi-hop VPN
- Onion Over VPN – anonymizes traffic by routing it via Tor Network
The service is secure and does not keep any logs. It operates under The British Virgin Islands jurisdiction. It supports other protocols like Shadowsocks, IKEv2, and OpenVPN. For extra security, it has DNS leak protection and an internet kill switch.
This VPN provider is excellent for both torrenting and streaming. It unblocks lots of Netflix libraries and works with Disney+. If you’re annoyed by ads – it also includes an ad-blocker.
Surfshark allows you to connect an unlimited number of devices with the same account and has a 30-day money-back guarantee on all its plans.
Private Internet Access
Private Internet Access is a well-known VPN service in the industry. It recently released its version of WireGuard for Windows, Mac, Linux, Android, and iOS.
PIA’s WireGuard connections remain private and no IP addresses are leaked. This WireGuard VPN provider has a strict no-log policy and other privacy features. This includes internet kill switch, IP leak protection, and block for ads and trackers.
Private Internet Access has a server network with more than 3000+ servers in 67 locations. Many of them support P2P traffic and have unlimited bandwidth. It is also one of the few VPNs that allow setting up port-forwarding.
Private Internet Access has a 30-day money-back guarantee on all its plans.
- Supports WireGuard on all platforms
- Currently WG is in Beta testing phase
- No Traffic or Request logs
- Can be used with 10 devices simultaneously
- Unlimited Bandwidth and good speeds
- 3200+ Servers in 29 Countries
- 30-day money-back guarantee
TorGuard has full WireGuard support for all Windows, macOS, and Linux users. Android and iOS apps will also feature WireGuard support soon.
The setting up is not as straight-forward as NordVPN. You have to enable the setting on your account panel, download the config files, and import them. Only then you could create the WireGuard tunnel.
TorGuard has a no-logs policy and does not keep any connection or usage information. It has 3000+ servers in 50+ countries, allows unlimited bandwidth, and has good speeds.
This WireGuard VPN provider also has lots of customizable features. You can set up port forwarding, SSL based VPN, traffic obfuscation, or pick a Dedicated IP.
There’s no IP or DNS leaks and, of course, it has an internet kill switch.
AzireVPN started to support WireGuard since 2017. You can use it on Windows, macOS, iOS, Android, Linux apps, and routers.
It has specific WG clients for every OS and configuration files available for import. This service is a privacy-focused service that keeps no-logs.
Their network has 12 key locations around the world. It allows bandwidth, P2P traffic, and even fully supports IPv6.
AzireVPN uses strong encryption offered by WireGuard. Their servers do not have hard-drives to avoid any logging.
For privacy, the service accepts payments with multiple cryptocurrencies – even with DogeCoin (much wow!).
Advantages of WireGuard VPN
This protocol solves the most common problems the VPN consumers face.
Here are the advantages of the WireGuard VPN.
High speed and performance
One thing that this VPN protocol outshines the others is the speed. The official website states:
“[…] WireGuard lives inside the Linux kernel means that secure networking can be very high-speed […]”.
Such modern implementation contributes to fast speeds and performance. This can be noticed on many devices, especially mobile. For example, WireGuard also:
- Reconnects and authenticates fast
- Saves battery life on mobile devices
- Has better roaming support for mobile devices
- Has a more reliable and stable connection
Mobile device users should see the advantages when using it. It is especially powerful if you often change networks and move from WiFi to 4G connections. The mechanisms behind allow your device to quickly reconnect to a VPN server.
The protocol uses the newest and most modern scientific cryptographic techniques.
The WireGuard uses these encryption algorithms:
- Noise protocol framework
For more in-detail reading on cryptographic methods find it on the official website.
Secure and Auditable
Like OpenVPN, WireGuard is an open-source project too. That means that the code is publicly visible and can be read by anyone. The protocol’s security-first design principle is what makes it easily auditable.
The codebase is just around 5000 lines of code when in comparison OpenVPN alone takes up to 120 000 LoC. Such a simple approach and small codebase have it’s security advantages:
- Easily auditable
- Easily understood
- Has a minimal attack surface
- Less prone to vulnerabilities and bugs
In the early stages, WireGuard was only released for a Linux Kernel. It was lacking support for other OS like Windows. Once the development started, the team released the drivers for platforms all platforms. Windows, macOS, iOS, and Android can now work with the protocol.
The cross-platform support enabled the wider protocol adoption in the industry. VPN providers started to get interested and built it into their apps.
WireGuard’s concept is called crypto-key routing. It uses the public key and IP address pairs to route and manages the connections. The simple interface allows the connections to be set up with a few command lines. It does not need to manage any connection states or know what’s under the hood. All is taken care of by the protocol itself.
Of course, there were some trade-offs made when designing the protocol. It comes with some drawbacks that are keeping away the VPN providers from mass adoption. There are some technical challenges concerning privacy.
Here are WireGuard’s drawbacks:
Logs and stores the user’s IP address on the server
WireGuard has a default mechanism of storing the user’s IP addresses on the server’s RAM. Once you reboot the VPN server or restart the WG interface, the IP addresses are deleted. But, this is not enough for the cybersecurity companies that offer a no-log policy.
VPN providers must come up with ways to ensure the privacy of their users when using WireGuard. Only a few VPN services came up with a solution implied by the protocol’s design. For example, NordVPN solved the logging issue with it’s double NAT system (NordLynx). Read it on their blog how they made it work.
Internally assigns a static IP address
WireGuard VPN providers pointed that it’s not ideal how the protocol assigns internal static IP addresses. The public key and IP pairing mechanism could potentially leak your IP externally.
The IP leak can only happen if you have installed malicious apps or when experiencing a WebRTC leak. But, WebRTC IP leak can expose your IP when using other VPN protocols too. So WireGuard, in this case, is as secure as other protocols.
WireGuard VPN is the next big thing in the industry. It is secure, fast, and uses the most modern technology. It’s a fairly new protocol few VPN providers have it on their apps. WireGuard’s inner mechanisms come short in regards to privacy. The best VPN companies try to engineer ways to ensure their user’s safety.
So far NordVPN offers the best solution with their Double NAT system called NordLynx. It is the easiest to use as it requires only to select a setting in the app.
