Today AWS announces the general availability of data grants in AWS Data Exchange, a new feature enabling any AWS customer to grant time-bounded, read-only data access to any other AWS customer. This feature is intended for customers who want to exchange data across organizations easily and securely. Data grants work seamlessly with all five AWS Data Exchange supported delivery types: Data Files, Amazon S3, Amazon Redshift, AWS Lake Formation (Preview), and Amazon API Gateway.
