Overview
Commercial Gmail and Google Workspace are used by millions of businesses but hold no FedRAMP authorization. They lack US-only data residency, FIPS 140 encryption, and the audit controls required for CUI. Many small subcontractors entering defense work use Gmail without understanding the compliance gap.

Deployment & Architecture
Deployment Model: Cloud SaaS (vendor-hosted)
Gmail (Commercial) has no FedRAMP authorization on record. DFARS 252.204-7012(b)(2)(ii)(D) requires an external cloud service provider to meet security requirements equivalent to the FedRAMP Moderate baseline — an authorization is the straightforward way to show that, but it is not the only one. Without one, the burden is on you to establish, document, and defend equivalency, and to meet the clause's incident-reporting and media-preservation obligations. Most contractors find an authorized alternative cheaper than carrying that burden.

Frequently Asked Questions
Is Gmail compliant for defense contractor email?
No. Commercial Gmail is not FedRAMP authorized. Google Workspace Government edition or Microsoft 365 GCC High are compliant alternatives.
Can I add encryption to Gmail to make it compliant?
Adding Virtru or similar encryption can help protect individual messages, but the underlying Gmail infrastructure still lacks FedRAMP authorization. This is a partial mitigation, not full compliance.
