Using Google Workspace Government in a Defense Contractor Environment
Google Workspace Government handles diverse CUI categories in defense contracts including technical specifications, financial data, contractor employee PII, and operational communications. Within CMMC Level 2 authorization boundaries, it typically serves as the primary email and collaboration platform for unclassified but sensitive communications. The tool's FedRAMP Moderate authorization provides strong baseline protections, but contractors must implement compensating controls including: DLP policies for CUI identification, retention policies aligned with contract requirements, and endpoint protection for devices accessing the service. DCMA/DIBCAC assessors evaluate Google Workspace Government favorably due to its FedRAMP authorization, but scrutinize the contractor's configuration including: user access controls (MFA enforcement), data sharing restrictions, mobile device management integration, and audit logging capabilities. Assessors particularly focus on how contractors prevent unauthorized CUI sharing through Google Drive external sharing and ensure proper data classification workflows are enforced within the platform.
Deployment & Architecture
Deployment Model: Government Cloud (FedRAMP boundary)
Google Workspace Government operates within a FedRAMP-authorized boundary. CUI can be processed within the authorization scope, but contractors must verify their specific use case falls within the system's security boundary as documented in the SSP.
Implementation Guide
For compliant deployment, migration from commercial Google Workspace to Government version requires 4-6 weeks. Export all organizational data using Google Takeout, coordinate user credential migration, and reconfigure organizational policies for CUI handling. Update authorization boundary diagrams to reflect FedRAMP service boundary and revise SSPs to document Google's inherited controls. Train users on CUI handling within the platform, particularly Drive sharing restrictions and Gmail classification requirements. If migrating away from Google Workspace Government (though unnecessary given its compliant status), consider Microsoft 365 GCC High (8-12 weeks migration) or on-premises solutions like Microsoft Exchange (12-16 weeks). Data migration involves exporting emails via IMAP, calendar data via CalDAV, and Drive files via API. Critical compliance documentation updates include boundary diagrams, data flow documentation, and incident response procedures for the new platform.

Compliance Cross-References
Google Workspace Government's FedRAMP Moderate authorization addresses multiple NIST 800-171 control families including Access Control (AC), Audit and Accountability (AU), and System and Communications Protection (SC). The platform triggers DFARS 252.204-7012 requirements for CUI protection and 252.204-7019 for incident reporting capabilities. Within CMMC assessment domains, it primarily impacts Access Control (AC) through identity management integration, Audit and Accountability (AU) via comprehensive logging, and System and Communications Protection (SC) through encryption and boundary protection. The tool's government cloud deployment satisfies CMMC's requirement for adequate security and supports Assessment Objective AC.L2-3.1.1 through AC.L2-3.1.22 for user access management, while its audit capabilities address AU.L2-3.3.1 through AU.L2-3.3.9 for system monitoring and logging requirements.
