You can mask sensitive data that appears in Data Vault search results. You can specify columns to mask and who to show masked data to based on the Data Vault access role of the user.

For example, a user has the privilege to access to an entity containing employee information. The user can access this entity through Data Discovery. However, if the user does not have the privilege to view sensitive information, the sensitive fields appear as Xs instead of the real value.
