Securing sensitive information with Data Masker is a simple, repeatable, push-button process which can be quickly applied whenever a test database is refreshed with production data. The consistent update of denormalized data after masking is simple. Data Masker contains custom synchronization rules for all three challenges: Synchronizing data at the row level, ensuring consistency of newly masked data between rows in a table, and maintaining the consistency of data between tables. Configured masking rules can be saved and re-run at any time.
