Sentinel — API Caller Classification

Know exactly who is calling your API

Classify every API caller as a browser, AI agent, CLI tool, or bot using TLS fingerprinting, header analysis, and behavioral patterns. Sentinel runs at the edge before your application logic executes, adding zero latency while giving you complete visibility into your API traffic composition.
