Oracle Advanced Security is a subscription-based software solution designed for businesses aiming to protect sensitive data from unauthorized access. It focuses on encrypting application tablespaces and implementing redaction policies to comply with data protection regulations. The software features Transparent Data Encryption (TDE), which ensures data-at-rest encryption, making it difficult for attackers to access sensitive information directly from storage, thereby securing the database layer.

In addition to TDE, Oracle Advanced Security provides data redaction capabilities that minimize the risk of unauthorized data exposure by redacting sensitive information before it leaves the database. This can be applied partially or fully, preventing large-scale data extraction into external reports or spreadsheets. The encryption is executed at the database kernel level, requiring no changes to existing applications, making it a seamless solution for businesses of all sizes.
