Here are some additional insights related to Open Source VPNs:

  1. Open-Source VPNs: The VPNs mentioned in the article are all open-source, meaning their code is publicly accessible. This transparency allows users and developers to inspect the code for any potential security flaws. It also means that the VPN software can be modified and improved by the community, leading to more robust and secure solutions.
  2. Risks of Open-Source Software: While open-source software has many benefits, it also comes with potential risks. These include the possibility of undiscovered bugs or vulnerabilities in the code, the potential for poor documentation or lack of customer support, and the risk of the software being abandoned by its developers. However, popular open-source projects, like the VPNs mentioned in the article, often have a large community of developers who actively maintain and improve the software.
  3. Open-Source VPNs and Trust: Trust is a critical factor when choosing a VPN. With proprietary VPNs, users must trust the company to respect their privacy and handle their data securely. With open-source VPNs, users can verify the security practices themselves by inspecting the code. This transparency can build trust and confidence in the VPN.
  4. Open-Source VPNs and Customization: Open-source VPNs can be customized to suit specific needs. This is particularly beneficial for businesses or advanced users who require specific features or configurations.

Remember, while open-source VPNs offer many benefits, they should be used as part of a broader approach to online privacy and security. It’s also important to choose a VPN that is actively maintained and has a strong community of developers.

Additionally, while VPNs enhance online privacy, they are not a silver bullet. Some online activities, like accepting cookies from websites, can still expose your online behavior. It’s important to use VPNs as part of a broader approach to online privacy and security.


While there are many VPN options available, open-source VPNs offer a level of transparency and control that proprietary VPNs can’t match. They allow you to see exactly how your data is being handled, giving you more control over your online privacy. Hopefully the information above provided a great overview of the different options available to pick and start from.
