The Cipherstash Encrypted Data Storage Solution
Problem
Agents hold your database credentials, and prompt injection is the number one LLM risk. CipherStash caps the blast radius: agents return only what the requesting user can decrypt. The attack still executes. The exfiltration does not.
Solution
Your database never sees your data. Queryable encryption for Postgres. Your data stays encrypted while your app is using it, and only an identity-bound policy can decrypt a value.

Australian Clients
Are leading clients include Amber Electric, Journalia, BNDRY, Talentblocks
Key Features
Postgres stores, indexes, and searches ciphertext. Only an identity-bound policy can decrypt a value. This is Data Level Access Control.
One platform: searchable encryption, value-level access policies, on-demand keys, and a cryptographic audit trail. Built into the Postgres you already run.

Verified Recommendations for Cipherstash
We picked Cipherstash to encrypt customer data across Postgres and DynamoDB from our TypeScript Lambdas so we could overcome a compliance bar that was preventing our international expansion. Cipherstash was fantastic.
John Barton, CTO of Amber Electric
Why we started Cipherstash
We started this company because the old threat model broke when humans left the loop. The database was readable to anyone who reached it for thirty years. That fact is gone.
