The report documents that Myanmar's military has used its TSG-based infrastructure to execute targeted throttling and selective shutdowns of specific services and platforms, not only blanket internet shutdowns. This includes selective disruption of VPNs and circumvention tools during periods of civil unrest, demonstrating that Myanmar's censors have operationalized the granular per-service traffic control capabilities documented in the Geedge/MESA leak.

The report traces the specific corporate pathway through which Geedge Networks exported GFW-derived technology to Myanmar: via front companies, shell entities, and Belt and Road Initiative contract frameworks that obscure the Chinese state's direct involvement. The report names at least three intermediary entities used to transfer equipment and technical personnel to the Myanmar military, and documents that the same export channel was used for ongoing product updates post-deployment.

§4, §6 policy

Justice for Myanmar documents that Geedge Networks supplied Myanmar's military junta with GFW-derived surveillance and censorship infrastructure under Belt and Road frameworks following the February 2021 coup. The deployed system (Tiangou Secure Gateway / TSG) incorporates the same DPI, active-probing, and ML-classifier capabilities as the domestic Chinese GFW, giving Myanmar one of the most technically capable censorship systems in Southeast Asia.

§3, §5 deployment

Article 19 documents that Iran's National Information Network (NIN / SHOMA) was designed with explicit reference to China's Great Firewall as a model, with institutional mirroring: Iran's Supreme Council of Cyberspace parallels China's Cyberspace Administration of China, and both governments share a "cyber sovereignty" doctrine used to justify domestic content controls and cross-border technology transfer. The report frames Iran's filtering infrastructure as deliberately architected to replicate GFW capabilities, not as an independently developed system.

Article 19 documents that Iran combines technical filtering with formal coercion of major foreign platforms (including Telegram, Instagram, and WhatsApp) to comply with content removal orders under threat of full blocking. The report notes that Iran's 2022 Women Life Freedom protests accelerated platform blocking when foreign operators refused compliance, demonstrating that the censorship system operates in two modes: coerce-and-allow for compliant platforms, block for non-compliant ones. Domain fronting via these platforms is therefore subject to sudden revocation if political conditions change.

MCCI (AS197207) blocks proxy IPs proportionally to observed connection volume: the more connections a phantom IP receives, the faster it gets blocked. A controlled experiment with a fresh /27 IPv4 subnet divided into 7 /30 sub-ranges with increasing weights confirmed that higher-weighted subnets were blocked first, demonstrating that the censor infers proxy IP reputation from traffic rate rather than from a static blocklist.

The report documents IMSI-catcher and mobile-network interception deployments in Pakistan that complement fixed-line DPI infrastructure. Mobile broadband users (dominant internet access mode in Pakistan) face surveillance at both the carrier level and via OTT platform coercion, with major platforms (YouTube, Twitter/X, TikTok) receiving and complying with blocking and content takedown orders from PTA, reducing the scope of accessible content even for users not running circumvention tools.

Amnesty International's 102-page investigation identifies a multi-vendor surveillance stack deployed in Pakistan: Chinese DPI (Geedge/MESA-derived), Canadian social-media monitoring (Netsweeper), and Emirati commercial spyware (Pegasus and FinFisher). The system enables deep packet inspection, SNI-based filtering, and traffic-shape classification at national scale, including targeted interception of encrypted messaging apps and VPN traffic.

InterSecLab's 76-page analysis of the Geedge/MESA leak (based on nine months of indexing and translating >100,000 documents) characterizes the Tiangou Secure Gateway (TSG) product line as a commercially deployable detection stack that combines deep packet inspection, real-time mobile subscriber monitoring, active probing, ML-based traffic classifiers, and granular per-region rule sets. TSG is not a research prototype — leaked documentation includes deployment timelines and client government interactions for Kazakhstan, Ethiopia, Pakistan, Myanmar, and one unnamed country, with censorship rules explicitly tailored to each region.
