You might also hear “WireGuard” refer to the app you can run on your devices as well. WireGuard is a VPN protocol-the way that a client (like your computer or phone) communicates with a VPN server. However, WireGuard’s architecture allows it to support obfuscation tunnels as a layer on top. If, for example, you’re trying to get through the Great Firewall of China, WireGuard by itself won’t do the trick. The WireGuard project does not seek to build a VPN that counters deep-packet inspection. If you want to use a VPN on a device where you can’t install apps, you’ll need to use a different protocol. Even though WireGuard offers client apps for every major platform, it doesn’t work without extra software except on some Linux distros. On the server side, setting up WireGuard is not much harder than configuring SSH, a task that nearly every IT professional is familiar with.ĭespite those advantages, WireGuard also suffers from some issues: You can download ready-to-go client apps for desktops and mobile devices from the platform app store. Both the client and server parts of WireGuard are really easy to install. Plus, its low-level component lives within the Linux kernel (on servers and Linux desktops), making it faster than userspace VPNs. Plus, it’s very small and simple in relation to older protocols, meaning that security researchers can audit it much more easily. Compared to other VPN software, WireGuard chooses smart, modern cryptographic primitives with secure defaults. Other VPN protocols sometimes feel brittle or clunky by comparison. It stays connected in situations where other VPN protocols would falter. WireGuard connects and reconnects fast, even when you’re roaming across networks. In a nutshell, WireGuard is a newer protocol, so it has some great advantages and some growing pains. In this article, you’ll learn what the hype is all about-and how WireGuard can help you protect your browsing. An early review from Ars Technica found that it connected and reconnected much faster than other protocols and that its cryptographical choices meant that it was more secure too. Major tech and programming personalities like Linus Torvalds, the creator of Linux, have praised it as a “work of art” compared to earlier VPN protocols like OpenVPN and IPSec. The new WireGuard VPN protocol has made a big splash lately.
