American academics presenting at USENIX Security 2026 analysed more than 100,000 files leaked from Geedge Networks and found source-code overlap between the company's Tiangou Secure Gateway firewall and China's Great Firewall, confirming TSG as one of the filtering system's known traffic-censorship components. Only one of three characterised DNS injectors matched Geedge behaviour, indicating the system involves multiple vendors. The leak also exposed Geedge's export business, giving Western governments concrete visibility into the commercial proliferation of Chinese state censorship technology — directly relevant to APAC internet-freedom debates and to Australian organisations assessing supply-chain exposure to Chinese networking vendors.
