Five Best Open Source VPNs (Updated November 2019)Last Updated by Mackenzie Pringle on June 28, 2019
If you’re not interested in paying for a VPN service, fed up with the throttled free plans out there, and you’ve just exhausted every available free trial. What’s your next move?
Luckily there are alternatives. These days, there is an open source version of almost every app or protocol available, including cybersecurity software and VPN clients.
These days there are hackers, cyber-criminals, ISPs, advertising networks, and government agencies looking to gather personal information. Data which can be used intrusively or maliciously.
Without a VPN you’re leaving yourself vulnerable to these threats.
What is an Open Source VPN?
Open source software is licensed to be developed and maintained by a community rather than a single company. It allows anyone to access and alter the code. Open source software is often free or much cheaper than a proprietary alternative.
Thankfully, open source VPNs are known for being reliable, due to having more people involved with the development and able to pick up on bugs or flaws in implementation.
A VPN itself allows you to securely connect to a server in a remote location which facilitates internet access, allowing you to bypass geo-restrictions, censorship, while also providing other benefits.
Why Use an Open Source VPN?
An open source VPN is the only VPN protocol that’s fully safe and secure. Open source VPNs are available for all major platforms, so there is little reason to consider anything else.
An open source VPN client will allow you to use the VPN provider’s configuration files, but it does require you to download and import them into the client.
Open source VPNs are more complicated to set up, but there are always plenty of step-by-step guides available. It might take a bit more time, but even a novice can do it.

What if you Don’t Want an Open Source VPN?
While most open source VPNs are free, they require repeat commissioning, some networking knowledge, and IT command skills to run smoothly.
If you’re not confident in your technical abilities but you still want a private, safe, and secure network connection, you can use a commercial VPN that will do the hard work for you.
Our recommendation is ExpressVPN, which provides many beneficial features.

Open source VPNs have many benefits that allow you to protect your data, no matter where you are. Although, they do require some setup and technical know-how.
Once an open source VPN is set up, you’ll be glad for the added security it offers. However, if you decide that open source VPNs aren’t the right fit for you, and you don’t mind shelling out a little extra cash, then we suggest choosing a user-friendly third-party VPN instead.
