In my 10+ years experience in web hosting and cyber security, I\u2019ve noticed that security is really an important thing you need to consider if you have an online business. There are a lot of hackers out there on the internet who keep a secret eye on your hard work that you store on a server. <\/p>\n\n\n\n

And to secure that data on the server, you use a VPN. <\/p>\n\n\n\n

A server, or let\u2019s say a virtual server already has a firewall setup, so why is VPN needed to re-tunnel the internet connection? See! A firewall is like a security guard who chooses who can access your server, while a VPN acts as a secure connecting subway for your data. That\u2019s why choosing the right VPN option is really important.<\/p>\n\n\n\n

But the problem comes when you are not able to choose which VPN to go with. <\/p>\n\n\n\n

Here in this guide, I\u2019m going to do a detailed comparison between the two best VPN providers, WireGuard vs OpenVPN based on its performance in terms of speed of the connection after re-routing and security.<\/p>\n\n\n\n

I have spent the last 10+ months running hosting infrastructure and testing tunnels on live servers. My research team has deployed both protocols on real VPS servers, over and over again to check its security.<\/p>\n\n\n\n

We have personally tested both the VPNs on our servers and then derived the comparison.<\/p>\n\n\n\n

You are here to pick one for your server. You want speed, you want security, and you want the right fit for your use case. I will give you all three. By the end, you will know which VPN to install on VPS.<\/p>\n\n\n\n

Quick Answer: <\/strong>WireGuard is faster and simpler to run. OpenVPN is older, more flexible and better at slipping past strict firewalls. Both are secure when set up right.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

WireGuard vs OpenVPN at a Glance<\/h2>\n\n\n\n

Before we go deep, here is the fast comparison. My team built this table from our own tests and from the official docs of both VPNs.<\/p>\n\n\n\n

Read that table twice. It already tells the whole story. The rest of this guide explains the why behind each information, so your pick is the right one.<\/p>\n\n\n\n

Keep this in mind as you read on: <\/strong>Fast does not always mean better for you. The best security protocol is the one that matches the job your server has to do.<\/p>\n\n\n\n

What Is WireGuard?<\/h2>\n\n\n\n

WireGuard is a modern VPN protocol built for speed and clean, simple code. It creates a secure tunnel between two points at the network layer.<\/p>\n\n\n\n

It landed in the Linux kernel in 2020, and that changed the game for self-hosted tunnels. My team runs it as the default on most of our VPS builds today.<\/p>\n\n\n\n

How WireGuard Works<\/strong><\/h3>\n\n\n\n

WireGuard uses a short handshake based on the Noise framework (a modern set of rules for secure key exchange). It sets up the tunnel in one quick round trip.<\/p>\n\n\n\n

Each peer is known only by its public key, a small 32-byte value. There are no long certificate chains to manage. <\/p>\n\n\n\n
