About
Operating a VPN in a highly restricted country (like China, Iran, Russia, or the UAE) is very different from simply trying to watch another country's Netflix. In heavily restricted regions, governments use Deep Packet Inspection (DPI) to look at your internet traffic. If they spot the "signature" of normal VPN protocols (like standard OpenVPN or WireGuard), they block that connection instantly. To break through, a VPN needs specialized obfuscation technology—essentially wrapping your encrypted VPN traffic inside an innocent-looking layer of normal HTTPS web traffic.
