## Support for Transparent Data Encryption
<a name="custom-managing.tde"></a>

RDS Custom supports Transparent Data Encryption (TDE) for RDS Custom for Oracle DB instances.

However, you can't enable TDE using an option in a custom option group as you can in RDS for Oracle. You turn on TDE manually. For information about using Oracle Transparent Data Encryption, see [Securing stored data using Transparent Data Encryption](http://docs.oracle.com/cd/E11882_01/network.112/e40393/asotrans.htm#BABFGJAG) in the Oracle documentation.
