How to Find Qualified Managed Service Providers for CMMC

Finding a qualified managed service provider (MSP) for Cybersecurity Maturity Model Certification (CMMC) compliance can determine whether a defense contract remains active or is removed from consideration. With CMMC 2.0 now being phased into Department of Defense (DoD) contracts, the streamlined levels and self-assessment requirements shift more responsibility onto contractors. 

Many internal teams lack the resources to handle this added workload. Therefore, it’s critical to partner with a qualified MSP to navigate the complex, time-consuming certification process and maintain a competitive edge. Not all vendors are equal. Here’s how you can find a qualified MSP for CMMC.

What Makes a Managed Service Provider “Qualified” for CMMC?

General IT support is not the same as regulatory-driven cybersecurity implementation. A qualified MSP should provide:

• Demonstrated CMMC and NIST SP 800-171 experience
• Secure cloud architecture capabilities
• A defined shared responsibility matrix
• Documentation, audit readiness and regulatory support
• Staff qualifications and U.S.-person compliance
• Service model clarity
  
  

Before evaluating providers, clarify your certification target level and identify whether you need gap assessment, remediation, ongoing managed services or all three.

Where to Find Qualified Managed Service Providers for CMMC 

To simplify your search for the best in the industry, here’s a roundup of top managed service partners making CMMC achievable for defense contractors.

1. NeoSystems

NeoSystems has extensive experience supporting government contractors, and its approach reflects that background. The company holds a CMMC Level 2 certification with a perfect 110/110 score, demonstrating full alignment with the standard and the ability to safeguard controlled unclassified information (CUI) in accordance with program requirements. That credential signals that you’re working with a provider that has already met the same benchmark your organization is preparing to achieve.

Beyond its own certification, NeoSystems guides organizations through audit preparation and assessment readiness. You enter the validation prepared, with structured evidence, clearly mapped controls and fewer last-minute documentation gaps. System security plans (SSPs) and plans of action and milestones (POA&Ms) are built into the process, so your compliance record reflects how your infrastructure actually operates. NeoSystems also provides secure, managed environments designed to meet federal requirements, including a FedRAMP-ready community cloud solution. 

Continuous monitoring services extend that assistance beyond certification, keeping security controls active, documented and aligned over time. Together, this combination of certification experience, compliance support and infrastructure preparedness enables defense contractors to integrate CMMC readiness into daily IT operations rather than treating it as a one-time checklist.

2. Summit 7 Systems

Summit 7 Systems is a well‑established vendor specializing in cybersecurity, compliance and managed services for DoD suppliers and the Defense Industrial Base (DIB). The company focuses heavily on Microsoft‑based solutions built on Microsoft 365 GCC High and Azure Government. 

The company supports adherence to CMMC 2.0, NIST SP 800-171, DFARS and ITAR through structured cloud architecture and ongoing compliance services. Clients receive the technical implementation and the regulatory alignment needed to protect CUI within Microsoft ecosystems. Summit 7 also holds dual CMMC Level 2 certifications — one for its corporate environment and one covering its managed services scope, including MSP and MSSP offerings.

The firm received Microsoft's U.S. Partner of the Year award for compliance. Its pricing and engagement models reflect this deep expertise, which makes it a strong fit for mid‑to‑large contractors with complex Microsoft cloud environments.

3. Kieri Solutions

Kieri Solutions is an authorized CMMC Third‑Party Assessment Organization (C3PAO), which means it performs official CMMC Level 2 evaluations. This significant credential signals deep familiarity with what assessors actually look for. Note that under conflict-of-interest rules, an organization that prepares you for the accreditation cannot conduct your official review. Therefore, Kieri's dual capability serves clients depending on where they are in the process.

The firm is recognized for a practical, structured approach to compliance that includes its Kieri Compliance Documentation. It provides prewritten policies, procedures and system security plan guidance based on real assessment outcomes. It also has Microsoft‑centric reference architecture designed for CMMC Level 2 and NIST SP 800‑171 alignment.

These tools and templates are particularly useful for organizations that want clear implementation guidance without the overhead of enterprise‑scale program management. The pricing is also more on the accessible end, which makes it ideal for small businesses pursuing CMMC Level 2. 

4. C3 Integrated Solutions

C3 Integrated Solutions is a U.S. Defense Industrial Base‑focused MSP and compliance provider founded in 2008. It achieved dual CMMC Level 2 certifications for its MSP and MSSP operations through a third‑party assessment. This demonstrates its alignment with the standards and ability to secure managed environments accordingly.

The company’s C3 Suite — including C3 Command and C3 Catalyst — offers prescriptive managed solutions that help defense contractors shorten timelines and meet the technical and organizational requirements of CMMC Level 2.

C3 also supports clients with compliance strategy and secure cloud deployments, including Microsoft 365 GCC High and Azure Government. It provides operational cybersecurity services rooted in an understanding of NIST 800‑171 and DoD standards.

5. Red River

Red River uses a staged, step-by-step approach to CMMC compliance. The main advantage it offers is stability, as you can keep business operations running while regulatory work moves forward in the background. 

Its model covers the full compliance arc. Gap assessments establish a clear starting point so you know exactly where you stand against the formal evaluation. That way, you don’t overspend on controls you already meet. The custom remediation planning maps out what actually needs to change, so instead of reacting to issues as they surface, you follow a structured roadmap that aligns with assessment expectations. Plus, employee training ensures that the people handling controlled CUI truly understand the weight of their responsibilities. 

With Red River, you can be assured that transparency runs through every phase. Strong documentation practices and third-party risk audits are built into the process. You develop a defensible compliance record over time. When the validation process approaches, your evidence is already organized and tied to each control objective. After certification, Red River provides continuous monitoring and 24/7 managed security services. Your defense posture stays aligned with CMMC requirements even as systems, users and vendors change.
