Zero-Knowledge Privilege
A security architecture ensuring that highly sensitive, privileged legal data cannot be read or accessed by the AI provider or underlying LLM.
Attorney-client privilege is the foundation of the legal profession. Passing unencrypted M&A term sheets or litigation strategies to a public LLM API violates this privilege. Vigil employs a Zero-Knowledge Privilege architecture. Documents are encrypted client-side and converted into irreversible vector embeddings. When external LLM reasoning is required, Vigil uses autonomous context masking to pseudonymize all sensitive entities (e.g., swapping "Google" with "Entity A") before the prompt leaves the secure perimeter. For maximum security, Vigil can deploy entirely air-gapped swarms on-premise.
