Before sending sensitive material such as client lists, medical records or contracts to an external model, requests are routed through this proxy: real fields are replaced with realistic fake values, and after the model responds, the original values are restored locally. Users get usable model output while the real data never leaves.
It replaces manual de-identification — previously handled by legal, compliance or data engineering, slowly and with gaps. Judgment: this kind of pre-model middleware sits exactly where rising compute cost meets tightening compliance, and law firms, clinics and accounting practices are natural starting points. Integration method and restoration reliability still need verification.
