Manage Tags
Connecting a Snowflake object tag to ALTR automatically enforces ALTR access governance to all columns assigned to that tag. When a tag is connected, ALTR applies masking policies and access rules to every column that carries that tag, simplifying governance at scale.
Tags provide a higher-level abstraction than individual column connections. Instead of connecting columns one at a time, you can tag columns in Snowflake and then connect the tag to ALTR. Any new columns assigned the tag are automatically governed.
For more on how tag-based and column-based governance compare, refer to Column and Tag Connections. Tags are currently supported for Snowflake data sources.
ALTR supports both native masking (policies run inside Snowflake) and default masking (policies call ALTR’s external function). You can also choose between default masking, tokenization, and format-preserving encryption when connecting a tag. See Native Masking for a detailed comparison.
