Top CMMC MSPs: How to Choose a Managed CMMC Compliance Provider

Quick Answer: BEMO is the top CMMC MSP for US defense suppliers on Microsoft 365 that need fully managed IT, security and compliance. It holds CMMC Level 2 certification and is a Cyber AB Registered Practitioner Organization. Firms with internal IT capacity may be better served by an advisory provider.

A prime asks for your SPRS score. A flow-down clause lands in a subcontract. Someone forwards you DFARS 252.204-7012 and asks who is handling it.

Most defense suppliers call their current IT provider and get a yes. Eighteen months later, they discover that yes covered less than they assumed.

Here, we talk about the stage after that. You have accepted you need outside help. Now you need to know which top CMMC MSP candidates are real, how to tell the difference, and what the work costs before you take a sales call.

BEMO published this guide and we're in the ranking below. The criteria come first, and the sections that follow say where we're the wrong choice.

Key Takeaways

• A CMMC MSP does not need its own certification unless it stores, processes or transmits your CUI. If it does, it needs one.
• Cyber AB registration is public. Check it yourself in the marketplace rather than trusting a logo on a website.
• Level 2 needs managed IT, managed security and pre-assessment advisory. Few providers do all three.
• Scope decides cost. The cloud you land in and the size of your CUI boundary move the number more than the certification itself.
• Most programs stall on evidence collection, not implementation. Ask any provider who produces evidence in month fourteen.
• At BEMO, we run compliance and security implementation end to end for small and mid-sized defense suppliers. See what the engagement covers on our CMMC compliance services page.

Top CMMC MSPs at a Glance

Here are the best CMMC MSPs right now.

Verify every status yourself. Registration and assessor relationships change, and the Cyber AB Marketplace is the record, not a vendor page.

What a CMMC MSP Actually Does, and What It Does Not

A CMMC MSP runs the IT and security environment that your CMMC scope sits inside. That means identity, devices, email, logging and the controls that produce evidence.

What it does not do is grant you a certificate. Only an authorized C3PAO can assess you for Level 2, and no provider can assess a client it also serves.

The gap that catches buyers is narrower than it sounds.

Most managed IT firms can secure a network. Far fewer can run CMMC services for MSP clients who have CUI, a GCC High tenant and an assessor asking for artifacts.

Ask a candidate to describe the last Level 2 assessment they supported, by name of framework version and by what the assessor asked for. Vague answers here are the whole signal.

CMMC MSP vs MSSP vs RPO: The Three Roles Buyers Keep Conflating

Three different jobs get sold under similar language. Level 2 needs all three, and most firms buy one and assume they bought all of them.

The shared-responsibility split is where engagements go wrong. A provider may own logging while you still own the policy that says how long logs are kept.

Get that split written down before you sign. If a CMMC managed service provider cannot produce a responsibility matrix, it has not done this before.

Levels matter here too. Level 1 is a self-assessment against 15 requirements. Level 2 is 110 requirements aligned to NIST SP 800-171 and, for most CUI contracts, a third-party assessment. The difference between CMMC Level 1 and Level 2 decides how much of this you need.

Does Your MSP Need to Be CMMC Certified?

Only if it stores, processes or transmits your CUI. An MSP that touches your CUI environment is in scope and is assessed with you.

Certification is still worth asking about when it is not required. A provider that has been through a C3PAO assessment has produced the same artifacts it is asking you to produce.

At BEMO, we hold CMMC Level 2 certification and operate under the same standards we deliver.

CMMC Consultant or Managed CMMC Provider: Which One You Need

A CMMC consultant advises. A managed provider implements and then operates. Both are legitimate and they solve different problems.

Buy CMMC consulting services when you have an IT team with capacity, and the missing piece is knowing what good looks like. You get a roadmap and your team executes it.

Buy managed CMMC compliance when the honest answer to who will collect evidence every month is nobody. A roadmap handed to a team of two IT generalists becomes a document nobody opens.

The test is ownership, not budget. Name who will run the program in month nine, when maintenance replaces the interesting work.

The Criteria That Separate a Real CMMC Compliance Company From a Reseller

Before hiring a provider, ask about a C3PAO assessment it helped a client complete. What evidence did the assessor request, what problems came up, and how did the team resolve them? Those details tell you more than a sample policy document or a promise to get you certified in weeks.

Use these six checks to compare providers before committing to one.

1. Cyber AB registration you can look up. Registered Practitioner Organization status is public. BEMO is listed as a Cyber AB Registered Practitioner Organization. A logo on a homepage is not evidence.
2. A named C3PAO relationship. Ask which assessor the provider has worked with and on what. A CMMC compliance company that has never been in the room during an assessment is guessing at what assessors accept.
3. GCC High capability, and a view on whether you need it. The wrong answer is automatic yes. The question of whether CMMC requires GCC High turns on your contract clauses, not on the framework.
4. A scope-first process. If the first conversation is about licensing rather than where your CUI lives, the provider is selling a bundle.
5. 24/7 security operations. Ask who monitors alerts overnight and who responds when something goes wrong. Confirm where the analysts work, whether another company provides the service, and what data they can access. Your provider should explain how that setup meets your contract’s data handling and access requirements.
6. Co-managed or fully managed, stated plainly. Both models work. What does not work is discovering in month four that your two-person IT team was assumed to be doing the policy work.

Run those six against any list of CMMC compliance companies and most of the names drop out. That is the list doing its job.

How We Evaluated These CMMC Compliance Services

The providers here were compared on the six criteria above, in that order, with registration and assessor experience weighted highest because they are the two a buyer cannot fix later.

Worth naming the pattern in this category. Almost every ranked list of CMMC certification companies on page one is published by one of the companies, which appears at number one, with no disclosure anywhere on the page.

BEMO published this one, and we appear first because of the fit we actually win, which is Microsoft-native fully managed delivery for firms under roughly 500 people with no compliance staff. On other criteria, other providers win, and the comparison below says which.

Hold us to the same standard. Verify the registrations yourself, and you will see that our evaluation criteria are as objective and rigorous as it gets.

Top CMMC MSPs and Compliance Providers Compared

We compared these providers using the six criteria above to help you find the right fit. Here are the best CMMC MSPs.

1. BEMO (Best for Microsoft-Native, Fully Managed Delivery)

At BEMO, we run the IT, the security operations and the compliance program as one engagement, on a Microsoft 365 stack. That means the team configuring your conditional access is the team producing the evidence for it.

What the engagement covers:

• Managed IT across identity, devices, email and helpdesk.
• Managed security, including monitoring and incident response.
• Pre-assessment advisory as a Cyber AB Registered Practitioner Organization.
• Policy, SSP and POA&M work, plus the monthly evidence collection behind them.
• GCC and GCC High migrations, with a view on which one your contract actually requires.

We hold CMMC Level 2 certification ourselves, so we have produced the artifacts we ask you to produce and sat on our side of a C3PAO assessment.

Best for: Small and mid-sized defense suppliers, roughly under 500 people, already on Microsoft 365 or willing to move, with no internal compliance staff.

Not for: Firms committed to a non-Microsoft stack, firms that only want software, and firms whose IT team has the capacity to run the program and only needs direction.

2. Summit 7 (Best for Larger DIB Suppliers and Prime Contractors)

Summit 7 is a Microsoft-focused managed services provider serving the Defense Industrial Base (DIB). It helps defense suppliers manage their cloud environments and prepare for CMMC Level 2 assessments.

Its services and experience include:

• Managing Microsoft cloud environments.
• Supporting CMMC Level 2 implementation and assessment preparation.
• Providing Azure expertise backed by Microsoft specializations.
• Working with defense suppliers and prime contractors.

Before signing, confirm who will support your account, what the service covers, and which tasks your internal team must handle.

Best for: Larger defense suppliers and prime contractors seeking Microsoft-focused IT and compliance support.

Not for: Teams seeking only a gap assessment or occasional advice rather than ongoing managed services.

3. CyberSheath (Best for Security Operations and Compliance Under One Provider)

CyberSheath provides managed IT, security, and CMMC compliance support for defense contractors.

Its services include:

• Managing IT systems and security operations.
• Assessing compliance gaps and implementing controls.
• Providing Federal Enclave, its cloud-based enclave solution.
• Maintaining and monitoring systems after implementation.

Federal Enclave is worth considering if you want to limit where controlled unclassified information (CUI) is stored and accessed. Compare building an enclave with buying a managed solution before choosing an approach.

Best for: Defense contractors seeking managed security, IT, and compliance support from one provider.

Not for: Teams that only need a readiness assessment or occasional advice. Confirm the ongoing services and responsibilities included in your contract.

4. Assessor-Led Advisory Firms (Best for Firms With Their Own IT Team)

Advisory firms help your team understand CMMC requirements and prepare for an assessment. This category includes consultancies and Registered Practitioner Organizations (RPOs), rather than one specific provider.

Their services commonly include:

• Identifying gaps in your controls and documentation.
• Preparing your System Security Plan (SSP) and Plan of Action and Milestones (POA&M).
• Defining which systems and data fall within your assessment scope.
• Helping your team organize evidence and prepare for assessor questions.

For an advisory engagement, your team usually handles the technical fixes and ongoing maintenance. Confirm those responsibilities upfront, and distinguish readiness support from the independent assessment.

Best for: Organizations with an IT team that can implement changes but needs compliance guidance.

Not for: Teams that need a provider to make the changes, collect evidence, and maintain controls for them.

5. Compliance Platforms (Best for Firms That Will Operate Their Own Controls)

Drata and Vanta help your team track compliance and organize evidence. They are software platforms, so consider them if you have staff to implement and manage your controls.

These platforms help you:

• Map controls to requirements and monitor their status.
• Collect evidence from your existing tools.
• Create policies using templates and track employee acknowledgments.
• Organize evidence for your assessor to review.

Your team still needs to configure systems, customize policies, fix security gaps, and respond to assessor questions. At BEMO, we work with both platforms and provide that implementation and ongoing support.

Best for: Organizations with a compliance lead and an IT team that need tools to reduce manual work.

Not for: Organizations that need someone to implement controls and run the compliance program for them.

Choose based on the work your team can handle. A smaller supplier may need fully managed support, while a larger organization may already have the staff to run its own program.

BEMO's Compliance and Technology Partners, and Why We Chose Them

BEMO works with Microsoft, Drata, Vanta, KnowBe4 and independent audit firms to deliver compliance services.

We have commercial relationships with these partners, which we disclose here so you can weigh our recommendations.

We build on Microsoft: Entra ID, Intune, Defender, Purview and Sentinel. The platform supplies evidence for most of the 110 requirements, reducing manual collection and assessment time.

Drata and Vanta map controls to your framework and automate evidence collection. The choice usually depends on what your auditor accepts and what your team will use.

These platforms flag gaps. BEMO handles the implementation needed to close them.

KnowBe4 supports the required security awareness training. Firms such as Sensiba and A-LIGN assess your compliance independently of BEMO.

How to Choose a CMMC Managed Service Provider

Work through these decisions before comparing quotes so each provider prices the same scope.

• Scope your CUI first. Identify where it arrives, where it is stored and who accesses it. These answers determine the work and its cost.
• Choose co-managed or fully managed support. Be realistic about what your team has time to handle. The enclave build versus buy question is the same decision in a different form.
• Verify credentials in the Cyber AB Marketplace. Check the provider’s registration and the individual Registered Practitioners listed with it.
• Ask about C3PAO experience. Find out which assessors the provider has worked with, which clients it supported and what the assessments found. Ask for specifics.
• Compare costs once the scope matches. Make sure both quotes cover the same work and responsibilities before deciding which offers better value.

What CMMC Compliance Actually Costs

CMMC compliance costs include the initial build, ongoing managed services, licensing and a third-party assessment. Your total depends on headcount, cloud requirements, CUI scope and how much evidence collection is automated.

Use our CMMC Level 2 pricing calculator to estimate your costs. Enter your headcount, Microsoft environment and helpdesk needs to get a range in about three minutes.

Costs drop in years two and three once the build and policies are complete. You then pay for ongoing operations and evidence collection.

Budget separately for third-party CMMC assessment costs. Those fees go to the C3PAO, not your implementation provider.

Why GCC High and Scope Drive the Price

GCC High costs more because of its US-person support staffing and FedRAMP High authorization. CMMC itself does not drive that premium.

Scope has a bigger effect on cost. A 200-person firm that isolates CUI in an enclave brings only part of its environment into the assessment.

Your contract determines whether you need to meet GCC High requirements. Confirm that before requesting a quote.

Microsoft-Native Scope Makes the Audit Cheaper

An assessor wants evidence for every one of the 110 requirements in NIST SP 800-171. Collecting and reviewing that evidence takes time.

A single Microsoft stack brings those sources together: conditional access policies in Entra ID, device compliance in Intune, and sensitivity labels and DLP in Purview. Unified audit log retention is configured once.

With a scattered stack, evidence comes from six consoles and a spreadsheet. The same controls take several times the labor, and the assessor must work through inconsistent records.

Consolidation reduces that work, which is the strongest financial case for keeping the tools together.

The CMMC Cost Fallacy: What Buyers Get Wrong

The biggest mistake is treating CMMC as a certification fee. Most of the cost comes from implementation work the firm has put off.

DFARS 252.204-7012 has required NIST SP 800-171 compliance for years. For many firms, the surprise is the cost of meeting a clause they already signed.

The second mistake is letting the scope grow unchecked. Drawings and specifications spread across the tenant until the whole environment is in scope.

Review related files together when deciding where CUI lives. A drawing, delivery schedule, and parts list may reveal sensitive details when combined that are not clear from any file alone. Storing them together does not automatically make them CUI, but it can mean you need to reassess how the information is classified and protected.

Our Trust Issues episode, The CUI Scoping Mistake Blows Up CMMC Budgets, examines how scoping decisions affect compliance costs.

Setting a narrow boundary early is the biggest cost-saving step, and it is free. The focus should stay on protecting sensitive defense information, which is why CMMC exists.

Keeping CUI within a smaller group of systems also means deciding who needs access. For example, a salesperson may have access to technical drawings out of habit, even if the job no longer requires it. Managers need to confirm who needs those files and explain any changes to staff. Technology can enforce access restrictions, but people must make those decisions first.

In July 2026, the Department of Defense suspended later CMMC phases while a task force reviews the program.

Phase 1 remained in place. Self-assessments, SPRS postings, annual affirmations and the DFARS clause still apply. The verification step paused, but the obligations continue.

Why CMMC Programs Stall When Firms Run Them Internally

Internal CMMC programs stall when nobody owns remediation, evidence collection or ongoing maintenance. The same problems keep coming up.

• The gap assessment leads nowhere. An accurate 60-page report arrives, but nobody owns the fixes. Six months later, it is out of date.
• Nobody has time for evidence collection. Screenshots, access reviews and log exports need attention every month. That work is missing from everyone’s job description.
• The SSP and POA&M fall behind. Written for the assessment, they stop reflecting the environment as it changes. The assessor spots the mismatch.
• Compliance depends on teams outside IT. HR handles background checks, contracts handles flow-down clauses, and operations handles training. The compliance lead has no authority over those teams.
• The person who knows the program leaves. In a 40-person firm, one person can hold all that knowledge. Their departure puts the program at risk.

CMMC compliance services provide ongoing ownership of this work. The value becomes clear in the fourteenth month, when evidence and maintenance still need attention.

CMMC MSP FAQs

Does a CMMC MSP need to be CMMC certified itself?

An MSP needs CMMC certification only if it stores, processes or transmits your CUI. It then falls within your assessment scope. Certification shows a provider has produced the artifacts it asks you to produce.

What is the difference between an MSP, an MSSP and an RPO?

An MSP runs IT. An MSSP monitors security and responds to threats. An RPO is a Cyber AB Registered Practitioner Organization providing pre-assessment advisory. CMMC Level 2 needs all three functions, whoever supplies them.

How much does it cost to work with a managed CMMC provider?

Managed CMMC costs depend most on headcount, GCC High needs and CUI scope. A calculator gives a baseline range in about three minutes. The separate third-party assessment fee goes to the C3PAO.

Do I need GCC High, or is GCC enough?

CMMC does not require GCC High. Contract clauses often do, particularly for ITAR or export-controlled data. Data type and contract language determine the choice.

How long does CMMC Level 2 certification take?

Plan in quarters rather than weeks for CMMC Level 2 implementation, evidence and assessor scheduling. A narrow scope is the most reliable way to shorten it. Firms without formal NIST SP 800-171 work face the longest path.

Is BEMO itself CMMC certified?

BEMO holds CMMC Level 2 certification and is a Cyber AB Registered Practitioner Organization. We operate under the same standards we deliver to clients.

Can my current MSP handle CMMC?

Ask your MSP for Cyber AB registration, its C3PAO experience and a written responsibility matrix. A provider that cannot supply all three has not done a Level 2 engagement.
