Developers
Live in five minutes. Gateway or SDK.
Cerberus runs where your request already is, an in-app agent, not network middleware. Drop in the gateway or embed one middleware, and detection is on.

Quickstart
Three steps to your first detection.
01Install
Add the gateway in front of your API or the SDK inside your server. No traffic rerouting.
02Configure
Turn on agent detection and source-side PII hashing in a few lines. Sensible defaults ship on.
03Respond
Wire verdicts to your workflows: block, authenticate, rate limit, alert, ban.
Open source
Read the runtime. Run the harness.
The Cerberus runtime is open source. Inspect exactly how requests are scored, and test detections against a known-vulnerable API before you ship.
Quiet by default. On in five minutes.
