TDE Benefits¶
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), TDE enables centralized control, auditing, and rotation of encryption keys—critical for secure production environments.
