Amazon S3 now supports AWS PrivateLink for endpoints that have been validated under the Federal Information Processing Standard (FIPS) 140-3 program. Customers with security and compliance requirements can use FIPS-validated cryptographic modules when connecting to S3 while keeping their traffic within their Virtual Private Cloud (VPC). To get started, create a new or edit an existing interface VPC endpoint for S3 and configure it to use the FIPS S3 endpoint.
