8.2Why Data Masking Matters
| Without Masking | With Masking |
|---|---|
| Test environments contain real customer data | Test data looks realistic but is fake |
| Data breach in staging exposes real customers | Breach in staging exposes nothing sensitive |
| Compliance violations (GDPR, HIPAA) | Compliance by design |
| Cannot share test environments with contractors | Safe to share with anyone |
| Production data copy requires security approvals | Masked copy is safe to distribute |
