Agent Detection

Real-time identification of AI agents by their TLS handshake (JA4/JA4S), HTTP headers (JA4H), and certificate fingerprints (JA4X).

Signature Database

The largest catalogue of AI agent fingerprints. Covers LangChain, CrewAI, AutoGPT, Claude API, OpenAI SDK, browser agents, and more.

Webhook Alerts

Get notified when a new or unknown AI agent is detected on your infrastructure. Integrate with your SIEM or SOAR platform.

REST API

Simple JSON API for fingerprint lookups, agent classification, and bulk detection. OpenAPI 3.1 spec available.

Threat Intel

Track malicious agent patterns, credential-harvesting bots, and automated attack frameworks by their unique signatures.

Privacy First

All source IPs are anonymised. We fingerprint the software, not the operator. No PII is stored or shared.
