PII Redaction
Stripping or masking personally identifiable information from data before it reaches a model, a log, or a third party.
PII redaction detects and removes personal data — names, emails, phone numbers, government IDs — from text before it flows into a prompt, a training set, or an application log. It’s a required control anywhere an LLM pipeline touches user data, both because prompts sent to third-party model APIs are a real exfiltration surface and because logs are often retained (and read by more people) far longer than anyone expects.
