Sanitize Legal Data
Before Using AI.
Maintain attorney-client privilege while leveraging ChatGPT, Claude, Gemini, Copilot, and Grok. Protect PII from court documents and contracts locally.
Executive Summary: LEGAL
Legal professionals are at the forefront of the generative AI revolution, but they face the highest stakes for data leakage. Disclosing client items to an external LLM doesn't just risk a leak — it can waive attorney-client privilege. PrivacyScrubber provides an air-gapped, zero-trust workflow to protect affidavits, contracts, and court documents before they ever touch a third-party server. Our legal-specific detection engine is tuned to identify sensitive party names, case numbers, and litigation details, replacing them with verifiable tokens that you reveal locally after the AI completes its analysis.
Privacy Checkpoints
- Waiver of Privilege: Sending raw case data to AI may constitute a waiver of confidentiality.
- Regulatory Duty: Model training toggles often aren't enough to satisfy 'Duty of Care' for sensitive files.
- Air-Gapped Workflow: Ensure every contract review starts with a local protection cycle.
- Discovery Risk: Protect unreleased evidence from entering third-party AI training sets.
Identified Risks & Solutions
PII Detection Matrix
| Entity Type | Exposure Risk | Local Edge Control |
