Key Points
- The CMMC is a mandatory requirement that Defense Industrial Base (DIB) contractors must meet before being awarded a contract with the DoD.
- CMMC compliance is an ongoing commitment, as contractors must continuously enforce and validate applicable security controls to preserve DoD contract eligibility.
- CMMC-compliant IT services should incorporate regulatory alignment, covering security control enforcement, continuous monitoring, documentation upkeep, and audit readiness.
- MSPs must map all service functions to each CMMC compliance requirement, ensuring controls are consistently enforced and audit-ready.
- Continuous monitoring, compliance reporting, and automation are essential to maintain compliance between assessments while reducing audit findings.
While large enterprises often have ample resources to meet Cybersecurity Maturity Model Certification (CMMC) compliance, many small to mid-sized businesses (SMBs) struggle with compliance. To help meet compliance requirements, many SMBs hire MSPs to support their compliance and security operations.
MSPs delivering compliance-as-a-service solutions must first understand what CMMC compliance is, set clear expectations for clients, and structure their offerings to support ongoing compliance.
What is CMMC compliance?
The Cybersecurity Maturity Model Certification (CMMC) is a mandatory compliance requirement for contractors within the Defense Industrial Base (DIB)—a global network of public and private organizations that supports the U.S. Department of Defense (DoD).
CMMC utilizes a three-level framework, with each level adding new requirements on top of the previous ones. In addition, each tier signifies how strong a contractor’s cybersecurity practices must be, depending on the type of federal information it handles.
| CMMC level | Name | Who it applies to | Requirements |
| Level 1 | Foundational | Contractors working with Federal Contract Information (FCI) | Requires basic cybersecurity strategies as defined in FAR 52.204-21 to protect FCI. |
| Level 2 | Advanced | Contractors and subcontractors handling Controlled Unclassified Information (CUI). | Contractors must align with 110 security controls outlined in NIST SP 800-171. |
| Level 3 | Expert | Designed for contractors handling mission-critical CUI that are frequently targeted by Advanced Persistent Threats (APTs). | This level focuses on alignment with proactive cyber defense strategies, including additional controls based on NIST SP800-172. |
Before an organization can be awarded a contract with the U.S. Department of Defense (DoD), it must implement, operate, and maintain security controls as required for its applicable CMMC level.
Defining CMMC-compliant IT services
CMMC-compliant IT services integrate required security and compliance controls into daily IT operations. These services support ongoing compliance efforts by helping contractors maintain documentation, monitoring, and audit preparation activities over time.
Enforcement of the required CMMC security controls
CMMC compliance is tailored to align with every layer of a contractor’s IT infrastructure, alongside the required security controls based on their CMMC level. For instance, Level 2 contractors must deploy and configure controls across all 14 NIST SP 800-171 domains, including access control, incident response, and configuration management.
From an MSP standpoint, applicable requirements should be translated into technical configurations across client systems, networks, and endpoints.
Ongoing monitoring of systems and endpoint compliance
Continuous monitoring offers real-time visibility into system and endpoint status. These monitoring capabilities help detect anomalies and identify configuration drift, enabling MSPs to deliver proactive IT support before compliance gaps escalate.
This ongoing visibility allows MSPs to understand how a client’s environment aligns with CMMC controls and determine whether the organization remains compliant.
Maintenance of documentation and audit artifacts
Every required control enforcement should be documented and stored in a secure, accessible repository. Delivering compliant IT services includes the creation and ongoing maintenance of documentation, ensuring that evidence stays accurate and accessible to support audits.
Support for audit preparation and validation
Level 2 and Level 3 contractors undergo CMMC assessments conducted by certified third-party assessment organizations (C3PAOs). MSPs providing compliance management services must prepare clients for these assessments by conducting internal readiness reviews and closing known gaps, to name a few. In addition, ongoing validation strategies ensure that clients remain audit-ready between cycles.
CMMC compliance guide: An overview for MSPs
Effective CMMC-compliant IT service delivery requires tying the required regulatory controls to measurable compliance outcomes. For MSPs supporting DIB contractors, the following core practices define what that strategy would look like in practice.
Align service delivery with compliance requirements
Mapping CMMC-compliant services directly to the requirements they support strengthens their defensibility while providing a clear audit trail.
Effective alignment should cover the following:
- Link each service delivered to the specific CMMC controls or requirements it supports.
- Ensure consistent enforcement of the required CMMC controls across systems.
- Maintain accurate documentation that reflects actual implementation.
- Validate that security controls remain effective and properly implemented over time.
Through this alignment, MSPs can deliver credible CMMC support while minimizing gaps between service delivery and what clients must demonstrate during assessments.
Provide ongoing compliance monitoring
Ongoing monitoring ensures that controls are frequently validated to detect silent configuration drift. For MSPs delivering CMMC-compliant IT services, monitoring strategies should include:
- Real-time visibility into system configurations and security status across all managed systems.
- Automated detection of deviations from established compliance baselines to prevent surprise audit findings.
- Ongoing validation of security controls to ensure they remain effective and compliant over time.
- Structured tracking of remediation activities to create a clear record of how identified issues are resolved.
Together, these capabilities provide MSPs and their clients with assurance that the environment remains compliant between audit cycles.
Deliver structured compliance reporting
Both documentation and reporting help ensure that organizations can demonstrate alignment during assessments. Effective reporting strategies should include system compliance status, vulnerability metrics, access control, privilege activity, and incident tracking.
These reports must be standardized, consistently generated, and retained in a format that supports audits.
Incorporate automation into service delivery
IT automation offers consistent control enforcement across managed systems, reducing manual workflows while speeding up configuration drift detection and response. Through this, MSPs can deliver CMMC-compliant services at scale without the proportional increase in overhead.
Support audit readiness and validation
CMMC assessments are rigorous, and organizations must be able to demonstrate that they meet applicable CMMC requirements. MSPs can support this process by preparing documentation packages, assisting clients during assessor interactions, and helping remediate gaps identified before or during assessments.
Align services with client expectations
Many DIB contractors rely on MSPs to support their compliance efforts and maintain required security controls.. To meet these expectations, MSPs should provide services that support CMMC requirements through ongoing monitoring, documentation management, and regular compliance reporting.
These services should also support long-term compliance management, helping organizations adapt to evolving CMMC requirements and changes in business operations.
Integrate CMMC compliance within routine IT management
CMMC alignment demands consistent enforcement and validation to preserve client eligibility for DoD contracts. When MSPs embed compliance controls directly into their IT management strategy, they provide clients with the foundation needed to preserve compliance over time.
NinjaOne can help MSPs support up to 90% of CMMC Level 2 technical requirements through its comprehensive, FedRAMP Authorized platform. The platform provides centralized endpoint management, patching, automation, visibility, and reporting capabilities that support CMMC-related security and compliance operations.
