Shadow Protocol: Circumventing Censorship
The Shadow protocol is ZoogVPN’s advanced solution for securely circumventing internet censorship in heavily restricted regions like China, Russia, Iran, Egypt, and other countries with strict internet controls. We combine obfuscated proxy technology with a VPN to deliver a secure connection even in countries where traditional VPNs are blocked. Avoid firewalls and other restrictive measures without revealing that you’re using a VPN.
ZoogVPN’s tailored Shadow protocol combines obfuscated proxy technology with a VPN to circumvent censorship in regions like China, Russia, and Iran. Access the internet securely without revealing VPN usage, even in places where standard services are blocked.”
In many countries with solid internet censorship, internet service providers (ISPs) are required to block VPN traffic. Traditional VPNs often have detectable traffic patterns, which allow ISPs or firewalls to identify and block them using techniques like Deep Packet Inspection (DPI). This is a commonly adopted practice in China, Russia, Iran, Turkmenistan, UAE, Qatar, Turkey, and other regions where governments strictly manage access to the web.
The Shadow protocol is specifically designed to cope with such heavy blocks. Its performance lies in disguising VPN traffic, which is undetectable from regular HTTPS traffic. We apply this stealthy approach so our users can surf the web and access their beloved sites freely and securely, eliminating the most intense restrictions.
The Shadow protocol creates a failure-resistant combo, powered by a specific proxy and a VPN, using encryption and traffic obfuscation techniques to cloak your internet activity. This leaves no chance for ISPs and network administrators to determine that you're using a VPN, even in countries with advanced censorship measures. The VPN traffic appears as regular encrypted web traffic (HTTPS), so it can pass through firewalls and filters without being blocked.
This protocol is ideal for accessing content in China, Russia, Iran, Saudi Arabia, Vietnam, Turkmenistan, and other regions with heavy restrictions. It’s integrated into ZoogVPN’s apps, ensuring that your data stays private and your connection remains secure.
On top of blocking VPN traffic, some countries tend to block VPN apps. It makes access the websites and VPN apps practically impossible. For this purpose, we've designed a Manual IP resolution feature that helps to bypass this block as well. When you login into our application, choose Preferences > Manual API resolution IP and enter the IP address provided by our customer support upon request. We are working 24/7, so it will take only a few minutes to receive the necessary information.
