Previously accessible only over the public internet, FIPS 140-3 validated endpoints for S3 File Gateway can now be accessed through PrivateLink within a customer’s VPC, ensuring regulated workloads maintain encrypted, compliant traffic confined to the private AWS network. This includes the ability to create NFS and SMB shares that connect to Amazon S3 via FIPS interface endpoints.

Activation requires Storage Gateway software version 2.1.10 or later and is rolled out in eight AWS Regions. This development facilitates secure file transfer workflows adhering to federal encryption standards without exposing traffic over the public internet.
