Data Masking 
Data Masking for MongoDB
Discover the MongoDB data masking tool in Studio 3T Ultimate. Enable data compliance and bolster security with powerful field-level data obfuscation.
Try for freeCopy 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
Date: Substitute with random date and time, Substitute with fixed date and time
Boolean: Negate boolean value, Substitute with fixed boolean value
