Detection coverage
From basic connectivity to GFW scenarios
Choose nodes for five base methods, then use two GFW scenario checks for continuous monitoring and batch analysis.
GFW scenario checks
DNS Pollution uses dedicated check nodes. GFW Full combines common blocking methods and results from multiple nodes.

How it works
Detection results built for ongoing operations
Console manages scheduled tasks, history, and alerts. API v2 handles asynchronous batches. API v1 remains available for synchronous single-domain DNS pollution checks.
Console monitoring
Create scheduled tasks, select nodes and contacts, and review domain and node history over time.
Batch API
Use one API Key to submit up to 1,000 targets, then query each asynchronous batch with a six-hour execution deadline.
Clear results and alerts
Results use Normal, Indeterminate, and Blocked. Context-rich alerts are sent only after the configured trigger is met.
