PostgreSQL is the most popular open-source database among developers. It is one of the Top 5 databases in the world and it is fully open source and community driven. But is it secure - or could it be more secure? PostgreSQL's open source edition currently lacks Transparent Data Encryption (TDE). TDE is the way that data at rest protection can be done on the database level, ensuring the data is encrypted on the disk as well as in your backups and no application changes are required. To help give the community this added security benefit, Percona has created and is currently testing an open source TDE extension. This talk will cover our decision making process in creating the extension, it will go over data and findings that span the development of the extension, the added security benefits to your database, and point to what the future holds for TDE.
