What Is the Great Firewall
China's internet censorship system blocks thousands of websites and apps including Google, YouTube, Facebook, Instagram, WhatsApp, Twitter, Wikipedia, and many news outlets. It uses deep packet inspection (DPI) to detect and block VPN traffic.
Why CasperCloak Works in China
Most VPNs fail in China because the Great Firewall can detect VPN protocol signatures. CasperCloak uses quantum-resistant obfuscation to make VPN traffic indistinguishable from regular HTTPS traffic, bypassing DPI completely.
Setup Before You Travel
Download and install CasperVPN before arriving in China — the CasperVPN website and app stores may be blocked. Enable CasperCloak protocol in Settings. Download any offline maps and documents you might need. Save multiple server configurations as backups.
Tips for Reliable Access
Connect to nearby servers in Japan, Hong Kong, or Singapore for the best speeds. If one server is slow, try another. Keep CasperVPN updated — we regularly deploy new obfuscation techniques to stay ahead of censorship.

Is using a VPN in China illegal?
VPN use is a legal gray area in China. Unauthorized VPN services are blocked, but there have been very few cases of tourists being penalized for personal VPN use. Exercise discretion.
Will CasperVPN work on my iPhone in China?
Yes, as long as you install CasperVPN before entering China. The iOS App Store in China restricts VPN apps, so install beforehand.
