# Marketing Cloud Engagement Shield

Use Shield to protect your data and gain insights into who accesses that data. Shield combines security products to provide trusted encryption solutions with advanced Audit Trail functionality.

## Versions

There are two versions of Shield. One version uses a database that is shared with other Marketing Cloud Engagement customers. The other version uses a database that is only available to your account users. Both versions offer Encryption at Rest and an Advanced Audit Trail.

## Data at Rest Encryption

Data at Rest Encryption protects the underlying files stored in the file system. This feature is transparent to Marketing Cloud Engagement and doesn’t impact any functionality. Data is presented as plain text while encrypting the underlying file system. This feature doesn’t use application-layer or field-level encryption. For more information about enabling this feature, contact your Salesforce account executive.

## Advanced Audit Trail

Audit Trail allows admins to view access and activity records for Marketing Cloud Engagement. Receive Audit Trail records either through Automation Studio data extracts or through REST API extracts. Retrieve Audit Trail information periodically to use in your own tools.
