Data Masking for MongoDB

Discover the MongoDB data masking tool in Studio 3T Enterprise. Enable data compliance and bolster security with powerful field-level data obfuscation.

Copy and share data – the compliant way

Mask sensitive data throughout your pipeline

Choose a masking method per field

Anonymize each field as needed: show initials only, substitute entire fields or those matching regex, null values – you name it.

Preview the masked data

The JSON preview tab dynamically updates as you make changes to your collection.

Decide what happens to the original data

You can choose to leave the original collection as-is and export the masked copy to a new target collection – or overwrite the source collection directly.

Irreversible data masking

Once exported to the new target collection – or the source is overwritten, should you choose – the masked copy can never be unmasked.

Save data masking jobs as tasks

Each data masking job can be saved as a task that you can automate or schedule locally on your machine or remotely on your server.

Customizable, field-level static data masking

Obfuscate each field value type with the right masking method

All types: Not masked, Null out, Exclude field, Shuffle


String: Show only first or last characters, Mask entire string, Mask substrings matching regex, Scramble characters, Replace entire field with a fixed string


Numeric: Substitute value with fixed number, Add percentage to number, Subtract percentage from number


Array: Empty contents of the array
