+CipherStash Proxy provides a transparent proxy to your existing Postgres database.
+
+Proxy:
+* Automatically encrypts and decrypts the columns you specify
+* Supports most query types over encrypted values
+* Runs in a Docker container
+* Is written in Rust and uses a formal type system for SQL mapping
+* Works with CipherStash ZeroKMS and offers up to 14x the performance of AWS KMS
 
 Behind the scenes, it uses the [Encrypt Query Language](https://github.com/cipherstash/encrypt-query-language/) to index and search encrypted data.
