Frequently Asked Questions

  • Does EDB support Transparent Data Encryption (TDE) for PostgreSQL and EDB Postgres Advanced Server?

    Because EDB understands the importance of Transparent Data Encryption(TDE) to our Postgres customers, we have partnered with Thales, to ensure our customers can meet their security and compliance requirements. This includes PCI DSS compliance as well as many other security standards.

    Thales is the leading provider of Enterprise security solutions for multiple databases and sources including Postgres. We believe Thales CipherTrust Transparent Encryption is the best currently offered TDE solution for Postgres. The most notable reason being its excellent solution for Key Management and Key Rotation.

    EDB will continue to work with the community on database TDE solutions as part of the open source PostgreSQL offering. In addition to TDE we are actively pursuing solutions to ensure and improve the overall security posture of PostgreSQL including use cases for restricting Postgres super users access to data. We have some of our best people working to solve these use cases and plan to share something with the community shortly.
