Masking user data in Mautic

My query was: does Mautic allow users to Mask their data? For example, the email ids and client ids are extremely sensitive and we wouldn’t want it to be a part of data breach. Hence, if Mautic allows us mask that data in a way such that only a few can look at it, then Mautic will be providing the perfect solution to our problem.

Will love any information or insights on this.

Thank you.
