PII Redaction & Anonymization
AI agents that detect, classify, and redact sensitive information across documents, images, and databases — selecting the right anonymization strategy per jurisdiction and use case.

Our PII redaction service uses autonomous agents that go beyond simple pattern matching. The agents analyze document context to understand what constitutes sensitive information in each specific use case, select the appropriate anonymization strategy (redaction, pseudonymization, generalization, or synthetic replacement), and verify their own output for completeness.
The agents orchestrate multiple detection tools — NER models, regex engines, custom classifiers — and cross-validate results to minimize both false positives and missed detections. They handle documents, images (with OCR), databases, and structured data, automatically adapting their approach based on content type.
Jurisdictional compliance (GDPR, CCPA, HIPAA) is built into the agent logic. The agents know which rules apply, what must be redacted vs. pseudonymized, and generate compliance documentation alongside the anonymized output. Batch processing runs autonomously with human review only for edge cases.
