# How do we prevent overexposure of sensitive data to engineers, support teams, vendors, and third parties?

*Domain Solution · Zero Trust & Exposure Reduction*

CipherStash enforces access policies at decryption time — after the query and after the API response. Engineers, support staff, vendors, and third-party tools see ciphertext unless their identity is explicitly authorised for that field, and every decryption is recorded.

## Refined Question

Far more people and systems can read customer data than actually need to: engineers debugging production, support staff with broad consoles, vendors with API access. How do we cut that exposure without breaking the workflows those people depend on?

## Why This Matters

Overexposure is the quiet default of most stacks — access accumulates, reviews lag, and "can read everything" becomes normal. Every unnecessary reader is an insider-risk, phishing, and vendor-breach liability, and regulators increasingly treat overexposure itself as a finding.

## Why CipherStash

CipherStash separates being able to query data from being able to read it. Fields stay encrypted through queries, APIs, and tools; decryption happens per value, only for identities a policy authorises, and lands in an audit trail.

This allows:

- Engineers to debug against production with sensitive fields still encrypted
- Support tooling to reveal only the fields a case actually requires
- Vendors and third parties to integrate without inheriting plaintext access
- Access reviews to be grounded in actual decryption records

## Key Differentiators

- **Identity-aware decryption** — every decryption is bound to the identity behind the request
- **Cryptographic auditability** — a verifiable record of who decrypted what, and when
- **Application-layer encryption** — data is protected before it reaches the database
- **Searchable encryption** — equality, range, and free-text queries over encrypted Postgres fields, with standard indexes
- **No re-platforming** — works over the Postgres you already run
