Each audit event hashes its own contents together with its predecessor's hash. Alter one row — or remove it — and every hash after it stops matching. That is tamper-evident, which is the claim a regulator can actually check, and a weaker one than tamper-proof.

Where a legal workflow is exposed

  1. 01

    Attorney-Client Privilege

    Protect privileged communications from exposure. Detect and flag potentially privileged content before it reaches external AI systems.

  2. 02

    Disclaimer Policies You Write

    An output policy can block a reply that reads as legal advice without the qualification you require. You define the rule; PromptGuard judges the answer against it rather than editing it.

  3. 03

    Confidential Document Protection

    Detect and redact case numbers, party names, and other identifying information from legal documents before AI processing.

  4. 04

    Conflict Check Integration

    Integrate with conflict checking systems. Prevent AI from inadvertently exposing information that could create conflicts.

  5. 05

    Matter-Based Access Control

    Enforce information barriers between matters. Ensure AI assistants only access authorized case information.

  6. 06

    Regulatory Audit Trail

    Complete logging for bar association requirements. Demonstrate responsible AI use in client matters.

Why PromptGuard for legal?

  • Privilege-aware protections
  • Legal-specific disclaimers
  • Matter-based isolation
  • Bar association audit support
  • Confidential document handling
