Data classification for Snowflake

I am pleased to announce support for automatic data classification for Snowflake data source in Microsoft Purview Governance. This functionality is now generally available.

When you classify data assets, you make them easier to understand, search, and govern. Classifying data assets also helps you understand the risks associated with them. This in turn can help you implement measures to protect sensitive or important data from ungoverned proliferation and unauthorized access across the data estate. With automatic classification, customers can use 200+ built-in system classifications to easily identify sensitive information in the data source. Additionally, you can create custom classifications to automatically tag data that is specific to your organization like Employee Id or Product ID etc.

To automatically apply classification, simply set up a new scan.

Select either the default Snowflake scan rule set or create a custom scan ruleset.

Run the scan one time or schedule it to run at a regular interval.

Once the scan is complete, navigate to Data Catalog to view the assets discovered and classified by scan. If sensitive data was found, then you will see the relevant classifications on the schema.

Note: Self-hosted runtime (SHIR) version 5.26.404.1 or higher is required to classify data in Snowflake. You can find the latest version of Microsoft Integration runtime here.
