Protopia AI Stained Glass Transform
Mid-market and enterprise teams shipping prompts to hosted LLMs with proprietary data will find real value in Stained Glass Transform because it actually keeps plaintext out of provider hands without requiring you to run your own model. The tool transforms sensitive data before it reaches the LLM API, covers both PR.DS and ID.AM areas of NIST CSF 2.0, and deploys via AWS sandbox for low-friction evaluation. Skip this if your constraint is cost over data control, or if you're already committed to on-premise LLM deployment; the vendor's 22-person team also means you're betting on a smaller operation than incumbent security vendors.
