What is an Open Source VPN?

Virtual Private Network (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.
