Protect AI Alternatives: Where Model-Scanning, Application SDKs, and HTTP Gateways Sit in the Enforcement Stack
Protect AI started with model-supply-chain scanning and expanded into runtime LLM monitoring with Layer and Guardian.

This piece walks through the surfaces, what each covers, and how to map them to an enterprise audit obligation.
