The Tor Browser, designed for maximum anonymity, is actively blocked in countries that oppose private internet access. A VPN can help you connect to the Tor network even in countries that block direct Tor connections.
Tor Browser is blocked in China, Iran, Russia, Belarus, Turkmenistan, Venezuela. The blocks operate at the network layer — typically a combination of DNS poisoning, IP filtering, and SNI inspection. Domestic ISPs in restricted countries are required to drop traffic to Tor Browser's domains and origin servers, which is why typing the address into a browser returns a connection failure rather than a clean error message.
A VPN bypasses all three filtering methods at once. GhostShield's WireGuard tunnel encrypts every packet end-to-end, so ISPs see only encrypted traffic to a single GhostShield server IP. DNS resolves through our infrastructure, not the local ISP's. The TLS handshake happens between you and the GhostShield server — never directly to Tor Browser's domains — so SNI inspection finds nothing to block. Tor Browser itself sees a connection from a country where it operates normally and serves you the standard experience.
