OpenAI PrivacyFilter vs Protecto: 344 Annotations Compared
Most evaluations of a PII protection layer ask one question: did it find the sensitive data? That was the right question when data loss prevention meant blocking. A DLP system that found a Social Security number stopped the email, and nothing downstream needed to understand what had been stopped. AI workflows are different. Sensitive data can enter through prompts, tool calls, retrieved RAG context, agent memory, and model outputs, including paths that may sit outside traditional DLP inspection points.
