VPN (Virtual Private Network) software is generally purchased, but there are some free VPNs available. However, these are often considered basic and may have limitations compared to paid options. Here are a few examples of free VPNs you can explore:

1. OpenVPN Free - A popular and open-source VPN that offers basic security. It's free to use, but it has limitations like a short connection time and limited number of simultaneous connections.
2. OpenVPN Pro - A paid version of OpenVPN that provides more advanced features, including more secure connections and a larger number of simultaneous users. It costs around $19 per month.
3. OpenVPN for Windows - A free version of OpenVPN that's designed for Windows users. It's still limited in its scope compared to OpenVPN Pro.
4. OpenVPN for macOS - A free version of OpenVPN optimized for macOS. Again, it's limited in scope and offers basic security features.
5. FreeVPN for iOS - Some VPNs are optimized for iOS devices. Examples include OpenVPN for iOS and Phyther. These can offer basic security but are still limited in their scope.
6. FreeVPN for Android - Some VPNs are optimized for Android devices. Examples include StopSniff and Phyther. These can offer basic security but are still limited in their scope. It's important to note that using a free VPN can expose you to security risks. Always use a paid VPN for sensitive activities like browsing, online banking, or accessing private networks.
