A VP at an SAP shop told me recently: “Every time we copy production to our lower environments, PII leaks. And no, we’re not throwing an LLM at it. That’s a thousand times the compute of what we already run.”

He’s right.

Most of the PII redaction problem in enterprise data isn’t a neural network problem. It’s a lookup table problem. And the incumbents already solve it. SAP TDMS, Delphix, Informatica, IBM InfoSphere Optim. All schema-aware. All row-level. All deterministic.
