C3 Integrated Solutions: NIST & CMMC Compliance for Defense Contractors
C3 Integrated Solutions provides specialized IT, cybersecurity, and compliance services for the Defense Industrial Base, specializing in CMMC and GCC High.
Overview
C3 Integrated Solutions LLC is a premier full-service IT, cybersecurity, and compliance provider headquartered in Arlington, Virginia. The company specializes in serving the United States Defense Industrial Base (DIB), specifically targeting small to mid-market federal contractors who must navigate complex regulatory landscapes. C3 is recognized as a leading Microsoft Gold Partner and a designated Microsoft AOS-G (Agreement for Online Services – Government) partner, one of a select few authorized to sell and manage Microsoft 365 GCC High licenses.
The company’s core mission is to empower defense contractors to secure their intellectual property and maintain eligibility for federal contracts. Their service portfolio includes managed IT services, cloud migration and management, specialized cybersecurity solutions, and comprehensive compliance consulting. Since its inception, C3 has focused on the evolution of federal cybersecurity mandates, moving from initial DFARS requirements to the current CMMC framework.
C3 Integrated Solutions has established a significant market presence by bridging the gap between high-level regulatory requirements and the practical technical implementations needed to meet them. By focusing on the Microsoft government cloud ecosystem, they provide a standardized, scalable path for organizations to handle Controlled Unclassified Information (CUI) and International Traffic in Arms Regulations (ITAR) data. Their history is marked by a consistent commitment to the defense community, often serving as a thought leader in how cybersecurity policy impacts the agility of the private sector.
Positioning
C3 Integrated Solutions positions itself as the "Gold Standard" for defense contractor IT and compliance. Their market positioning is built on the pillars of authority, reliability, and specialized expertise. They consciously distance themselves from "generalist" MSPs by highlighting their status as one of the few partners authorized by Microsoft to handle the most sensitive government cloud environments.
Their messaging focuses on the concept of "Compliance Certainty." In a market where many contractors are overwhelmed by the ambiguity of CMMC and NIST requirements, C3 positions its services as a definitive roadmap to audit success. They target organizations that view compliance not just as a checkbox, but as a competitive advantage that allows them to win larger, more sensitive prime contracts.
Compared to competitors, C3 emphasizes a holistic "one-stop-shop" value proposition. While some firms only offer consulting and others only offer technical implementation, C3 positions itself as the partner that can handle the entire lifecycle: from licensing and architecture to ongoing managed security and audit support. This end-to-end positioning is designed to appeal to executive leadership looking to consolidate vendor risk and ensure accountability across their entire digital infrastructure.
Differentiation
The primary differentiator for C3 Integrated Solutions is their deep technical mastery of the Microsoft 365 Government Community Cloud (GCC) High environment. While many providers offer basic cloud migrations, C3 provides a comprehensive "Compliance-as-a-Service" framework specifically engineered to meet the stringent requirements of NIST SP 800-171 and the Cybersecurity Maturity Model Certification (CMMC).
Key product differentiators include:
- Steel Root Platform: A purpose-built, integrated technology stack designed to provide a "compliance-in-a-box" experience for defense contractors, significantly reducing the time to audit readiness.
- Managed GCC High Services: Specialized management of the sovereign Microsoft cloud environment, ensuring that data residency and sovereignty requirements are met without sacrificing user experience.
- Integrated Security Operations: Their security offerings are not bolted on but are natively integrated into the compliance framework, providing real-time monitoring and incident response tailored to federal reporting requirements.
- Documentation and Evidence Mapping: Beyond technical controls, their solutions provide the necessary documentation and evidence generation required to pass third-party assessments (C3PAO), which is often the most significant hurdle for contractors.
Ideal Customer Profile
The ideal customer for C3 Integrated Solutions is a Small to Mid-Sized Defense Contractor (SMB/SME) within the Defense Industrial Base (DIB).
- Company Size: 20 to 500 employees.
- Industry: Aerospace, Defense, Engineering, and Specialized Manufacturing.
- Technical Maturity: Currently using Microsoft 365 Commercial but needing to move to GCC High due to regulatory pressure.
- Budget Range: Organizations with an annual IT/Security budget of $50k - $250k+ who view compliance as a mandatory cost of doing business.
- Team Composition: Companies with a limited internal IT staff who need a specialized partner to handle the "heavy lifting" of security operations and compliance documentation.
Best Fit
- DIB Contractors seeking CMMC 2.0 Level 2 Compliance: C3 excels at taking small-to-mid-sized defense contractors from a state of non-compliance to audit-readiness using the Microsoft 365 GCC High environment.
- Companies Migrating to GCC High: When a business wins a contract requiring ITAR or EAR data handling, C3 is a top-tier choice for the high-stakes migration from commercial tenants to the Microsoft Government Cloud.
- Organizations Lacking In-House Cyber Resources: For firms that cannot justify a full-time internal SOC or CISO, C3's Managed Services provide the continuous monitoring and incident response required by DFARS 252.204-7012.
- Microsoft-Centric IT Environments: C3 is best for companies already committed to the Microsoft ecosystem who want to leverage their existing licensing to meet regulatory hurdles rather than buying disparate third-party tools.
Offerings
- Steel Root Managed Services: The flagship offering. A comprehensive "Compliance-as-a-Service" package that includes the Microsoft 365 GCC High tenant management, security monitoring, and documentation.
- CMMC/NIST 800-171 Assessments: High-level gap analysis and readiness reviews for companies at the start of their compliance journey.
- GCC High Migration Services: Fixed-scope projects to move data, identity, and mail from commercial or on-premise environments to the Microsoft Government Cloud.
- Microsoft AOS-G Licensing: Direct procurement of Microsoft 365, Power Platform, and Azure Government licenses tailored for the DIB.
- Managed SIEM/SOC: A standalone security monitoring service for companies that already have a secure tenant but need 24/7 threat detection.

Introduction
Welcome to the Comprehensive Buying Guide for C3 Integrated Solutions. In the rapidly evolving landscape of Defense Industrial Base (DIB) requirements, C3 has emerged as a leading specialized Managed Strategy Provider (MSP) and Managed Security Service Provider (MSSP). This guide is designed for IT directors, compliance officers, and executives who need to navigate the complexities of CMMC 2.0, NIST 800-171, and ITAR regulations.
C3 Integrated Solutions distinguishes itself by focusing exclusively on the Microsoft Cloud, specifically the GCC High environment. As a Microsoft AOS-G partner, they offer a unique combination of licensing, implementation, and ongoing managed services. By reading this guide, you will understand how C3’s "Steel Root" platform and specialized consulting services can transition your organization from a state of compliance risk to a secure, audit-ready posture that protects your ability to win and execute Department of Defense (DoD) contracts.
Key Features
- Microsoft GCC High Licensing & Implementation: As one of the few authorized AOS-G partners, C3 provides direct access to and configuration of the Microsoft Government Cloud, the gold standard for ITAR and CMMC Level 2 compliance.
- Steel Root Compliance Platform: A proprietary managed service framework that integrates Microsoft’s security stack into a pre-configured, hardened environment designed to meet all 110 controls of NIST 800-171.
- Managed Security Services (MSSP): 24/7 security monitoring, threat hunting, and incident response specifically tuned for the defense industry’s unique threat profile.
- Compliance Documentation Support: C3 doesn't just provide the tech; they assist in generating the System Security Plan (SSP) and Plan of Action and Milestones (POA&M) required for DoD audits.
- Secure File Sharing & Collaboration: Implementation of Microsoft Purview to ensure that sensitive data is encrypted, labeled, and restricted to authorized personnel only, even when shared externally.
- Endpoint Management: Using Microsoft Intune to ensure all devices (mobile and desktop) accessing the network meet strict security baselines before being granted access.
Use Cases
- The "Ransomware Recovery" Shift: A mid-sized aerospace parts manufacturer suffered a breach and realized their commercial IT provider couldn't meet DFARS reporting requirements. C3 migrated them to a hardened GCC High tenant, providing the logging and forensics needed to satisfy DoD investigators.
- The "New Contract" Sprint: A boutique engineering firm won a Navy contract requiring CMMC Level 2. C3 implemented a "Compliance Enclave"—a secure sub-environment for just the users working on that contract—allowing the firm to meet requirements quickly without migrating the entire company at once.
- The "Commercial to Government" Transition: A software company expanding into the federal market used C3 to mirror their commercial DevOps environment in Azure Government, ensuring their IP remained protected while meeting federal data sovereignty rules.
Pricing Models
C3's pricing is typically structured into three main components:
- Professional Services (One-time): This includes the initial assessment, tenant setup, and data migration. Pricing is based on the complexity of the data and the number of users.
- Microsoft Licensing (Monthly/Annual): As an AOS-G partner, C3 manages your GCC High licenses. Pricing is set by Microsoft but billed through C3, typically requiring annual commitments.
- Managed Services (Monthly Recurring): This is a per-user, per-month fee for the Steel Root platform and ongoing MSSP support.
- Note: Small shops (under 20 users) should expect higher per-user costs due to the fixed overhead of maintaining a GCC High environment. Medium-sized firms (50-200 users) see the best economies of scale.
Technical Requirements
- Identity: Active Directory or Azure AD (Entra ID) as the primary identity source.
- Workstations: Windows 10/11 Pro or Enterprise (Home editions are not supported for compliance).
- Mobile: iOS or Android devices capable of running Microsoft Authenticator and Intune Company Portal.
- Network: Business-grade firewall capable of supporting encrypted VPN tunnels and TLS 1.2+ inspection.
- Licensing: Requirement for Microsoft 365 E3 or E5 (GCC High versions).
- Hardware: TPM 2.0 chips on all laptops/desktops for hardware-level encryption.
Business Requirements
- Executive Buy-in for Compliance Costs: Moving to a secure environment like GCC High involves significant licensing and implementation costs; leadership must view this as a business enabler for defense contracts.
- Process Documentation Readiness: Buyers must be prepared to document internal business processes. C3 provides the technical framework, but the client must define who has access to what data.
- Change Management: Employees will face stricter authentication (MFA) and data handling protocols. A commitment to staff training and cultural shifts regarding security is essential.
- Defined Data Scope: Organizations must understand what CUI (Controlled Unclassified Information) they handle to ensure the environment is scoped correctly to avoid over-engineering or under-protecting.
Implementation Timeline
A typical C3 engagement follows a structured 4-6 month path:
- Discovery & Assessment (Weeks 1-4): Gap analysis against NIST 800-171 and CMMC standards, identifying data enclaves and user counts.
- Tenant Licensing & Setup (Weeks 5-8): Procurement of Microsoft GCC High licensing and initial configuration of the secure environment.
- Migration (Weeks 9-16): Migration of email, files (SharePoint/OneDrive), and identity (Active Directory) to the secure tenant. This is the most intensive phase.
- Security Overlay & Policy (Weeks 17-20): Implementation of Purview, Intune, and Defender policies. Finalizing the System Security Plan (SSP).
- Go-Live & Training (Weeks 21-24): User onboarding and transition to Managed Services for continuous monitoring.
Support Options
- US-Based Support: All support staff are US citizens located in the United States, a critical requirement for ITAR-compliant support.
- Tiered Help Desk: Standard business hour support with 24/7 emergency response for critical security incidents.
- Compliance Advisory: Access to subject matter experts who can interpret new versions of CMMC or NIST guidelines as they are released.
- Customer Success Portal: A dedicated platform for tracking tickets, viewing compliance dashboards, and accessing training materials.
- Quarterly Business Reviews (QBRs): Regular meetings to review security posture, update the SSP, and plan for upcoming regulatory changes.
Integration Requirements
C3 focuses on the Microsoft 365 Government Cloud (GCC High) ecosystem.
- APIs & Connectors: Full support for Microsoft Graph API for custom integrations.
- Identity: Integration with Azure Active Directory (Entra ID) for Single Sign-On (SSO) across compliant third-party apps.
- Security Tooling: Pre-built integration with Microsoft Sentinel (SIEM) and Defender for Endpoint (XDR).
- Legacy Systems: C3 can assist in bridging on-premise legacy ERPs with the cloud environment, though the goal is typically to move CUI-touching workloads entirely into the secure cloud.
- Data Formats: Support for all standard Office 365 formats with automated labeling and encryption via Microsoft Purview Information Protection.
Security & Compliance
- CMMC 2.0 Readiness: Purpose-built to meet Level 1 (Foundational) and Level 2 (Advanced) requirements.
- NIST 800-171: Direct mapping of all technical controls within the Steel Root environment.
- ITAR/EAR: GCC High data residency ensures that data stays within the US and is managed by US persons, meeting strict export control requirements.
- DFARS 252.204-7012: Full support for the "Reporting" and "Forensics" requirements (paragraphs c-g) which many commercial MSPs cannot meet.
- FIPS 140-2: Utilization of validated cryptography within the Microsoft Azure Government modules.
- SOC2 Type II: C3 maintains its own high standards of internal security to ensure they are a "trusted partner" in your supply chain.
