With the CMMC 2.0 Level 2 deadline approaching, 80,000+ defense contractors need compliant Microsoft 365 environments. BluetechGreen delivers FedRAMP-aligned GCC High migration, NIST 800-171 gap remediation, and continuous compliance monitoring built for government.
Microsoft 365 GCC High is not a configuration option — it is an entirely separate, US-sovereign cloud instance operated exclusively by US persons and subject to Department of Defense IL2 through IL5 security controls. Defense contractors handling CUI under DFARS 252.204-7012, organizations processing ITAR or EAR export-controlled data, and federal agencies requiring FedRAMP High authorization all require GCC High or Azure Government rather than commercial Microsoft cloud. We migrate organizations into these environments completely, without loss of data or disruption to operations.
Full tenant-to-tenant migration from commercial M365 or GCC Standard to GCC High. ITAR and EAR data isolation enforced at the infrastructure level. Dedicated sovereign infrastructure with CUI handling built into every workload — Exchange Online, SharePoint, Teams, and OneDrive.
IL4 and IL5 workload deployment on FedRAMP High authorized services. Continuous monitoring program aligned to NIST SP 800-137, including automated evidence collection, Plan of Action and Milestones (POA&M) management, and annual assessment preparation for Authorizing Official review.
Sovereign cloud deployment for classified-adjacent workloads. Air-gapped network architectures, dedicated compute for IL5 workloads, and classified workload support through Azure Government Secret where mission requirements demand physical separation from commercial internet infrastructure.
DFARS clause 252.204-7012 requires contractors to provide adequate security on all covered systems that process, store, or transmit Covered Defense Information (CDI) or Controlled Unclassified Information (CUI). Microsoft's commercial M365 environment does not satisfy this requirement because it is not operated exclusively by US persons, does not provide the data residency controls required for ITAR-regulated technical data, and does not hold the FedRAMP authorization level needed for DoD IL4 workloads. A contractor running CUI through commercial Teams or SharePoint is out of compliance with their contract — regardless of any other security controls in place.
GCC Standard (Government Community Cloud) is appropriate for state and local government organizations and federal contractors whose data requirements do not include ITAR, EAR, or IL4/IL5 classification. GCC High is required when the organization handles CUI under DFARS, processes export-controlled technical data, or is a direct contractor or subcontractor to the Department of Defense with access to CDI. The two environments are entirely separate tenants — data cannot flow between GCC High and GCC Standard without explicit export controls, and migrating between them requires a full tenant-to-tenant migration, not a configuration change. We assess which environment your organization requires and build the migration plan accordingly.
Microsoft Azure Government and Microsoft 365 GCC High both hold FedRAMP High Provisional Authority to Operate (P-ATO) granted by the FedRAMP Joint Authorization Board. This means the infrastructure layer is authorized — but your organization's deployment on top of that infrastructure must still be configured to maintain that authorization. A FedRAMP High ATO does not automatically flow down to your system. You are responsible for implementing the controls in your System Security Plan that are not covered by Microsoft's shared responsibility model. We document exactly which controls Microsoft inherits on your behalf and which your organization must implement and document independently.
Executive Order 14028 directed federal agencies to adopt Zero Trust security architectures based on NIST SP 800-207 by the end of FY2024. The OMB memorandum M-22-09 set specific Zero Trust goals across identity, devices, networks, applications, and data. Defense contractors and vendors to federal agencies are expected to demonstrate equivalent Zero Trust posture. We implement the full Microsoft Zero Trust stack — Entra ID, Conditional Access, and Defender for Endpoint — aligned to NIST 800-207 and CISA's Zero Trust Maturity Model.
Every access request to CUI-containing systems evaluated in real time against identity signals, device compliance state, network location, and application sensitivity. Named location policies restrict GCC High access to approved networks and compliant devices. Break-glass accounts documented and monitored for emergency access scenarios.
Microsoft Entra ID as the authoritative identity plane for all GCC High workloads. Privileged Identity Management enforces just-in-time access to administrative roles with mandatory approval workflows and time-bounded elevation. Entra ID Protection monitors sign-in risk and enforces step-up authentication for anomalous access patterns targeting CUI systems.
Microsoft Defender for Endpoint deployed to all devices accessing GCC High. FIPS 140-2 validated encryption enforced via BitLocker on Windows endpoints. Device compliance policies require current security patch level, Defender real-time protection, and screen lock before any GCC High resource access is permitted by Conditional Access.
NIST 800-207 defines Zero Trust around five pillars: identity, device, network, application and workload, and data. For a defense contractor environment, each pillar has specific implementation requirements. Identity requires all users to authenticate through MFA with phishing-resistant credentials (FIDO2 or Microsoft Authenticator Verified ID) before accessing any CUI. Devices must be enrolled in Intune MDM and pass compliance checks before the identity pillar grants access. Network access is limited through micro-segmentation — users access specific GCC High applications, not the entire GCC High environment. Application workloads in Azure Government are protected by Azure Private Endpoints, eliminating exposure to public internet routing. Data classification with Microsoft Purview labels ensures CUI is identified, encrypted, and access-logged wherever it resides.
OMB memorandum M-22-09 established specific, measurable Zero Trust goals for federal agencies and set expectations for enterprise identity management, device security, network segmentation, application security, and data governance. Agencies are required to use phishing-resistant MFA for all enterprise users, maintain a complete inventory of authorized devices, encrypt all DNS requests and HTTP traffic, and treat all applications as internet-accessible. Defense contractors whose systems connect to or support agency environments inherit these expectations through their contract requirements. We align your GCC High environment to every M-22-09 pillar, providing documentation that maps your control implementation to each specific OMB requirement — ready for agency security review or CMMC assessment.
CMMC 2.0 Level 2 requires organizations to implement all 110 practices from NIST SP 800-171 and achieve third-party certification from a C3PAO assessor. The gap between a contractor's current security posture and full NIST 800-171 compliance is typically 40-60 controls — each requiring not just implementation but documented evidence of consistent operation. We deliver the full Level 2 certification pathway: gap assessment, remediation, System Security Plan documentation, and assessor-readiness preparation.
Comprehensive assessment of your current environment against all 110 NIST SP 800-171 controls across 14 control families. We score each control as fully implemented, partially implemented, or not implemented, and produce a prioritized remediation backlog with effort estimates and risk weighting. Assessment delivered as a written report within 10 business days.
System Security Plan authored to NIST SP 800-18 standards, documenting your CUI boundary, system categorization, all 110 control implementations, and responsible parties. Plan of Action and Milestones (POA&M) tracks every open finding with milestone dates and remediation owners — the exact format C3PAO assessors and contracting officers expect to review.
Post-certification continuous monitoring program aligned to NIST SP 800-137. Automated evidence collection for key controls, monthly compliance score reporting, change management review to identify new activities that bring previously out-of-scope systems into CUI scope, and annual self-assessment support before your tri-annual C3PAO reassessment.
NIST SP 800-171 Revision 2 organizes its 110 controls across 14 families: Access Control (22 controls), Awareness and Training (3), Audit and Accountability (9), Configuration Management (9), Identification and Authentication (11), Incident Response (3), Maintenance (6), Media Protection (9), Personnel Security (2), Physical Protection (6), Risk Assessment (3), Security Assessment (4), System and Communications Protection (16), and System and Information Integrity (7). The heaviest implementation burden falls in Access Control, Audit and Accountability, and System and Communications Protection — precisely the areas where most commercial IT environments have the largest gaps. GCC High satisfies many controls at the infrastructure level, but your organization's configuration and operational practices must satisfy the remainder.
The single most important step in CMMC preparation is accurately defining your CUI boundary — the systems, networks, and personnel that store, process, or transmit Controlled Unclassified Information. An overly broad boundary means implementing 110 controls across more systems than necessary, dramatically increasing cost and complexity. An overly narrow boundary risks CMMC assessment findings that invalidate your certification. We facilitate a structured CUI discovery process using Microsoft Purview content scanning, data flow mapping, and contract review to draw a defensible CUI boundary documented in your System Security Plan. A well-defined boundary is the single most important cost-reduction lever in CMMC Level 2 certification.
Third-party CMMC assessors (C3PAOs) examine both the existence and the operational effectiveness of your controls. Implementing a control is not enough — you must demonstrate that it operates consistently over time. Assessors review your System Security Plan for completeness and accuracy, test selected controls through interviews, document review, and observation, and examine your POA&M to verify that known gaps have scheduled remediation. Common assessment failures include: controls documented in the SSP that are not actually implemented in the production environment, audit log retention shorter than the 3-year minimum, missing multi-factor authentication on accounts with access to CUI, and absence of incident response plan testing evidence. We conduct a pre-assessment mock review that replicates the C3PAO examination process, identifying and remediating assessment failures before the formal assessment begins.
Nation-state threat actors specifically target defense industrial base organizations to exfiltrate CUI, intellectual property, and sensitive program data — often months before the intrusion is detected. CISA and the NSA Cybersecurity Directorate consistently identify defense contractors as among the highest-priority targets for advanced persistent threat groups. Our 24/7 SOC using Microsoft Sentinel provides continuous monitoring of your GCC High environment with detection rules tuned to defense sector attack patterns, MITRE ATT&CK mapping, and automated incident response playbooks that contain threats before CUI exfiltration occurs.
Microsoft Sentinel deployed as a cloud-native SIEM within your GCC High tenant. Data connectors ingest GCC High audit logs, Entra ID sign-in and risky user events, Defender for Endpoint alerts, Azure Government activity logs, and network flow data. GCC High-specific analytic rules detect: off-hours bulk CUI downloads, impossible travel sign-ins on accounts with CUI access, new inbox rules forwarding mail to external addresses, and privilege escalation patterns on accounts in the GCC High admin roles. Every alert is triaged by our analysts — no unreviewed notification queues.
Defense sector threat intelligence feeds integrated directly into Sentinel, including CISA Known Exploited Vulnerabilities catalog, NSA advisories targeting defense contractors, and ISAC threat data relevant to your prime contractor and subcontractor relationships. Threat intelligence enriches every alert with actor attribution, campaign context, and recommended defensive actions — giving your security team the context needed to prioritize response correctly rather than treating all alerts as equal priority.
Documented incident response plan aligned to NIST SP 800-61r2 and CMMC IR.2.092 through IR.2.093 control requirements. Automated Sentinel playbooks isolate compromised GCC High accounts within 5 minutes of confirmed credential compromise, trigger Intune remote wipe on affected devices, and generate the incident documentation required for CMMC evidence collection. Post-incident reports provide the chain-of-custody records needed if the incident requires reporting to DCSA or your contracting officer under DFARS 252.204-7012.
CISA and the FBI regularly issue advisories documenting specific tactics used by nation-state actors to compromise defense contractors. Common techniques include spearphishing targeting employees with CUI access, password spray attacks against GCC High authentication endpoints, exploitation of unpatched remote access infrastructure, and supply chain attacks targeting software used in contract work. Attackers typically operate inside target networks for 60 to 200 days before attempting data exfiltration — which means perimeter security alone is not sufficient. Our Sentinel deployment creates the behavioral analytics baseline that detects anomalous access patterns during the attacker's reconnaissance and staging phases, before CUI leaves your environment.
When a cyber incident occurs on systems covered by DFARS 252.204-7012, you have 72 hours to report to DCSA and preserve images of compromised systems. The 72-hour clock starts from when you discover or reasonably should have discovered the incident — not from when you complete your investigation. Our SOC documents the exact timeline from initial detection to containment in Sentinel's incident management workflow, producing a compliant DFARS incident report pre-populated with the required fields: date of discovery, type of compromise, systems affected, CUI categories potentially compromised, and remediation actions taken. We handle the DIBNET reporting submission on your behalf so your program managers can focus on continuity rather than compliance paperwork during an active incident.
