Choosing well
Which masking methods do I need?
Start by listing the sensitive fields and the kind of protection your workflow requires, then compare the masking methods each tool documents.
Check whether the tool also supports synthetic data if generated data is part of your plan.
Where does the software need to run?
Choose a deployment that fits your environment, such as self-hosted, Linux, Windows, macOS or web access, and verify support for your setup.
If you plan to manage masking through an API, check API access and the database connectors you need. Android support is not established by the platform details here.
Will it preserve relationships and let me subset data?
Check for referential integrity if linked records need to remain consistent after masking, and data subsetting if you need to work with a reduced dataset.
Compare the documented behavior against your database and workflow before choosing.
How should I compare plans and pricing?
Check whether a free plan covers the work you need, and compare paid pricing or trial terms before committing.
For example, DataVeil lists a free plan and paid pricing from $5,690 per year. IRI DarkShield lists a 30-day trial and pricing from $5,490; its listing says it has no free plan.
