# How do you add data security to Fly.io Postgres?

*Domain Solution · Fly.io Postgres*

CipherStash encrypts sensitive fields at the value level on Fly.io Postgres, so a breach yields ciphertext with no usable key. Every encrypted value carries a decryption policy enforced at decryption time, after the query and after the API response. Attackers with stolen application credentials decrypt nothing.
