Percona has launched its Transparent Data Encryption (TDE) extension for PostgreSQL, designed to secure sensitive data at rest without licensing fees or usage restrictions. TDE automatically encrypts and decrypts data at the database layer, protecting backups and transaction logs, with encryption keys stored separately. The pg_tde extension supports compliance with regulations like GDPR, HIPAA, SOX, and PCI DSS v4.0, and allows users to encrypt all database files, apply encryption at the table level, and maintain control over their encryption strategies. It integrates with Key Management Services (KMS) providers and requires a patched PostgreSQL server to function. Percona aims to extend pg_tde to Community PostgreSQL, with some code already contributed for review. The extension is included in the Percona Distribution for PostgreSQL, which also offers support and consulting services for TDE setup and configuration.
