AWS Storage Gateway now offers Federal Information Processing Standards (FIPS) 140-2 compliant endpoints in AWS GovCloud (US) Regions to protect sensitive information for regulated workloads. These endpoints terminate Transport Layer Security (TLS) sessions using a FIPS 140-2 validated cryptographic software module, making it easier for you to use Storage Gateway for regulated workloads. US Federal agencies and companies contracting with the US Federal government can now meet the FIPS security requirement to encrypt sensitive data.
