Where to Keep CUI and ITAR Data: AWS GovCloud (US) vs AWS Commercial US Regions

Engineering

DFARS 252.204-7012 requires any cloud provider that stores, processes or transmits covered defense information to meet security requirements equivalent to the FedRAMP Moderate baseline. AWS's commercial US Regions and GovCloud (US) both clear that bar. The difference shows up with export-controlled data, contract language and who may administer the environment.

Side by side

AWS commercial US Regions

AWS GovCloud (US)

FedRAMP

Moderate (FedRAMP now calls it Class C) for US East and US West

High (Class D)

Meets the 7012 cloud requirement

Yes, Moderate equivalent

Yes

ITAR

Not AWS's designated environment for ITAR

Designed for it: accounts only for US persons at US organizations; AWS personnel access limited to US citizens

Services

All

A subset, with new features often arriving later

Accounts and identity

Standard

Separate GovCloud accounts linked to a commercial account; separate IAM and Identity Center setup

Cost

Standard prices

Generally higher than commercial Regions for the same service

What neither does for you

The cloud provider's authorization covers its side. Your system security plan, the 110 NIST SP 800-171 requirements for your environment, user training, incident reporting within 72 hours and CMMC assessment are still yours. A GovCloud account configured carelessly is not compliant because of where it runs.

Which one

Question 1 of 2

Will the environment hold ITAR or EAR export-controlled technical data?

Our verdict

**AWS commercial US Regions:** meet the FedRAMP Moderate requirement for CUI under 7012, with every service and the lowest prices. A reasonable home for CUI that is not export-controlled, when contracts do not require more. **AWS GovCloud (US):** for ITAR and other export-controlled technical data, and for contracts or primes that require it. Accounts only for US persons working for US organizations, AWS personnel access limited to US citizens, FedRAMP High. Fewer services and later feature launches, and its own account and identity setup. Many firms run both: CUI enclave workloads in GovCloud, everything else in commercial Regions.
