How we measure circumvention tools
The COMT category covers anti-censorship tools and encrypted messengers — VPNs, Tor, Signal, Telegram, WhatsApp. When a regime is escalating censorship, these are usually the first targets, because they are the tools people use to evade everything else.
Voidly correlates network-level measurements (DNS, TCP, TLS, HTTP) from OONI, CensoredPlanet, IODA, and our own probe network. Each blocked domain is mapped to a Citizen Lab test-list category, and the topic API filters those measurements to category COMT.
Scoring: within a topic, a country's score is a percentile against the worst country in the same category — so the top-ranked country always scores 100. This avoids cross-topic distortions. Full methodology →
Example domains in this category: signal.org, telegram.org, whatsapp.com, torproject.org
