'''Transparent Data Encryption''' (often abbreviated to '''TDE''') is a technology employed by both [[Microsoft]] and [[Oracle Corporation|Oracle]] to [[encryption|encrypt]] [[database]] files. TDE offers encryption at file level. TDE solves the problem of protecting data at rest, encrypting databases both on the hard drive and consequently on [[backup]] media. It does not protect [[Data in transit]] nor [[Data in use]]. Enterprises typically employ TDE to solve compliance issues such as [[PCI DSS]] which require [[Data at rest]] be protected.

Microsoft offers TDE as part of its [[Microsoft SQL Server]] 2008, 2008 R2, 2012, 2014 and 2016 when released. TDE is only supported on the Evaluation, Developer, Enterprise and Datacenter editions of Microsoft SQL Server. SQL TDE is supported by [[Hardware Security Module]]s from Thales e-Security, Townsend Security and SafeNet, Inc.
