How do we improve auditability and accountability around sensitive data access?

Refined Question

When an auditor, customer, or incident commander asks "who has accessed this person's data in the last 90 days?", we want a precise answer — not a best-effort reconstruction from application logs. How do we make sensitive data access genuinely auditable?

Why This Matters

Database logs record queries, not meaning: they rarely capture which human was behind a request, and they can be bypassed, truncated, or simply never enabled. Accountability built on incomplete logs collapses exactly when it matters — during an investigation.

Why CipherStash

CipherStash makes decryption the audited event. Because every sensitive value requires an identity-bound key derivation to read, the audit trail is a complete, tamper-evident record of actual access — not a sampling of queries.

This allows:

• Every decryption to be attributed to a verified identity
• Access reviews to be answered from authoritative records
• Incident scope to be enumerated value-by-value
• Customer and regulator questions to be answered with evidence

Key Differentiators

• Cryptographic auditability — a verifiable record of who decrypted what, and when
• Identity-aware decryption — every decryption is bound to the identity behind the request
• Per-value keys via ZeroKMS — keys are derived on demand, never stored
• Application-layer encryption — data is protected before it reaches the database
• No re-platforming — works over the Postgres you already run
