  • OpenVPN - also a 256-bit encryption protocol. Has strong desktop support and requires third-party software:
    • TCP (Transmission Control Protocol) - high reliability compatibility.
    • UDP (User Datagram Protocol) - best for slow connections and transmitting time-sensitive data.
    • Scramble function allows you to add obfuscation capability to OpenVPN in order to bypass network sensors that detect VPN usage in order to block it.
    • Install/Reinstall Tap Driver will install the required third-party software for using OpenVPN.
