Amazon S3 expanded security and compliance options by supporting AWS PrivateLink for interface VPC endpoints validated under the Federal Information Processing Standard (FIPS) 140-3 program. This integration allows customers with regulatory requirements to access S3 endpoints using cryptographic modules compliant with FIPS standards while retaining communication confined within their VPC.
The feature is available in select US, Canada, and AWS GovCloud regions at no extra cost. To use it, customers configure interface endpoints for S3 to utilize FIPS-supported endpoints. This advance helps meet stringent security policies common in government and regulated industries by combining VPC isolation with certified cryptography for data in transit.
