# Supported security standards

> Security standards for Maestro in Automation Suite, including encryption at rest via PostgreSQL and the absence of Customer-Managed Keys support.

## Data encryption

Maestro in Automation Suite does not support Customer-Managed Keys (CMK) or application-level encryption.

Data encryption is handled at the database level. Maestro stores its data in PostgreSQL, which supports encryption at rest. Enabling database-level encryption is the responsibility of the database administrator and depends on the PostgreSQL configuration used in your deployment.
