Column-Level Security is now supported in Azure SQL Data Warehouse

Community Manager

Today we’re announcing Column-Level Security (CLS) for Azure SQL Data Warehouse, an additional capability for managing security for sensitive data. Azure SQL Data Warehouse is a fast, flexible and secure cloud data warehouse tuned for running complex queries fast and across petabytes of data.


As you move data to the cloud, securing your data assets is critical to building trust with your customers and partners. With the introduction of CLS, you can adjust permissions to view sensitive data by limiting user access to specific columns in your tables without having to redesign your data warehouse. This simplifies the overall security implementation as the access restriction logic is located in the database tier itself rather than away from the data in another application. CLS eliminates the need to introduce views to filter out columns for access control management.
