Maybe one day – maybe – Zero trust will solve many of our network security problems. However, if you want to make sure for the time being that there is no eavesdropper on your network, you need a Virtual Private Network (VPN).

There is only one small problem with commercial VPNs: many of them are not trustworthy. So what can you do Well, running yourself is of course the open source answer. And today, the VPN of your choice is Linux’s built-in VPN: WireGuard.

Why WireGuard instead of OpenVPN or IKEv2? Because it’s easier to implement while maintaining security and providing higher speeds. And when it comes to VPNs, it’s all about the balance between speed and security.

So if WireGuard is all of that, then why did it take so long to get into the Linux kernel? After all, its creator Jason Donenfeld first got the Ideas behind WireGuard in 2015.
