Daniel Schwalbe, DomainTools Head of Investigations and CISO, is sharing their work on "Inside the Great Firewall." This two-part research project analyzes an extraordinary 500–600GB leak that exposes the internal architecture, tooling, and human ecosystem behind China’s Great Firewall. 

Across both parts, you break down thousands of leaked documents, source code repositories, diagrams, packet captures, and telemetry that reveal how systems like the Traffic Secure Gateway, MAAT, Redis-based analytics, and modular DPI engines work together to censor, surveil, and fingerprint users at scale. Taken together, the research shows how the Great Firewall functions not just as a technical system, but as a living censorship-industrial complex that adapts, learns, and coordinates across government, telecoms, and security vendors.

The research can be found here:
