New post: Detecting Misuse with the Claude Compliance API 🔍

Mapping the Compliance API feed to your SIEM gets you IAM and access detections “for free”, but the real AI threats live in the message content: prompt injection, jailbreaks, exfiltration prep, shadow data flow.

So I built a prefilter → LLM judge → SIEM pipeline to catch them, with a working repo + Sigma rules to run offline.
