Dynamic data masking protects sensitive data at query time by transforming values based on user permissions, without changing the underlying data.
How does ALTR’s dynamic data masking work?
ALTR applies masking policies at runtime using a cloud-native policy engine, ensuring each user sees only the data they’re authorized to access.
Does ALTR replace Snowflake’s native masking?
No. ALTR builds on Snowflake’s native masking capabilities and extends them with centralized policy management and advanced controls.
What types of data can be masked?
ALTR supports masking for sensitive data types like PII, PCI, and PHI, including emails, phone numbers, and financial data.
Can masking policies be updated in real time?
Yes. Masking policies can be updated instantly and applied across all datasets, users, and environments without downtime.
How does ALTR scale masking across large environments?
ALTR uses tags, metadata, and classification to automatically apply masking policies consistently across datasets and pipelines.
Can dynamic masking be combined with other protection methods?
Yes. ALTR integrates masking with tokenization and format-preserving encryption to provide layered, flexible data protection.
