Governance Management in Snowflake

Snowflake provides functionalities to ensure governance for all data stored and accessed in Snowflake, in addition to accounts and users.

• Column-Level Security
  Apply masking policies to columns within tables or views.
• Row Access Policies
  Apply row access policies to tables or views.
• Object Tagging
  Track sensitive data for compliance, detection, protection, and resource usage.
• Tag-Based Masking Policies
  Combine object tagging with masking policy functionality to set masking policies based on tags.
• Data Classification
  Classify data that may contain personal and/or confidential information.
• Access History
  Audit user access history.
• Object Dependencies
  Audit how one object refers to another object through metadata, such as creating views that depend on table and column names.

However, it seems that most of the governance features are only available in Snowflake editions that are Enterprise or higher.
