Benefits of pg_tde¶

The benefits of using pg_tde are outlined below for different users and organizations.

Benefits for organizations¶

Data safety: Prevents unauthorized access to stored data, even if backup files or storage devices are stolen or leaked.
Enterprise-ready Architecture: Supports both single and multi-tenancy, giving flexibility for SaaS providers or internal multi-user systems.

Benefits for DBAs and engineers¶

Granular control: Encrypt specific tables or databases instead of the entire system, reducing performance overhead.
Operational simplicity: Works transparently without requiring major application changes.
Defense in depth: Adds another layer of protection to existing controls like TLS (encryption in transit), access control, and role-based permissions.

When combined with the external Key Management Systems (KMS), pg_tde enables centralized control, auditing, and rotation of encryption keys—critical for secure production environments.
