Why traditional masking fails modern data requirements

 Legacy masking creates a "utility gap" that stalls testing, analytics, and AI workflows: 

  • Masking breaks referential integrity: Inconsistent data across related tables, databases, and test environments impedes testing
  • Masking destroys data utility: Lack of statistical utility for analytics and AI
  • The shift to synthetic data: Replace masking with synthetic data generation
