With Immuta integration with Amazon Redshift, consumer and knowledge safety operations are managed utilizing an intuitive consumer interface. This weblog submit describes easy methods to arrange the combination, entry management, governance, and consumer and knowledge insurance policies.
Amazon Redshift is a completely managed, petabyte-scale, massively parallel knowledge warehouse that makes it quick and cost-effective to research all of your knowledge utilizing customary SQL and your current enterprise intelligence (BI) instruments. Right this moment, tens of hundreds of shoppers run business-critical workloads on Amazon Redshift. Amazon Redshift natively helps coarse-grained and fine-grained entry management with options comparable to role-based entry management, scoped permissions, row-level safety, column-level entry management and dynamic knowledge masking.
Immuta allows organizations to interrupt down the silos that exist between knowledge engineering groups, enterprise customers, and safety by offering a centralized platform for creating and managing coverage.
