Minimize plaintext exposure across your data stack

Refined Question

Sensitive data doesn't stay in the primary database: it flows into read replicas, warehouses, BI dashboards, admin panels, and debugging tools. How do we stop every one of those copies from being a plaintext exposure?

Why This Matters

Each downstream copy of plaintext multiplies the attack surface and the compliance scope. Securing the primary database achieves little if the same values sit readable in a warehouse, a dashboard cache, or a support tool screenshot.

Why CipherStash

Because CipherStash encrypts at the application layer, ciphertext is what propagates. Replication, ETL, and tooling all carry encrypted values; only an authorised identity at an authorised decryption point ever sees plaintext.

This allows:

• Downstream systems to inherit protection automatically, with no per-system work
• Analytics and internal tooling to operate without holding plaintext
• Exposure points to be reduced to the decryption paths you explicitly define
• Queries against encrypted fields to keep working where they are needed

Key Differentiators

• 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
• Identity-aware decryption — every decryption is bound to the identity behind the request
• Cryptographic auditability — a verifiable record of who decrypted what, and when
• No re-platforming — works over the Postgres you already run
