How to Choose a CMMC Consultant

By Shaheer Malik · Updated Oct 22, 2026

Pick a consultant that is registered as an RPO with the Cyber AB, has done Level 2 readiness for companies your size, scopes the work in writing, and does not promise you a certification: only a C3PAO can certify you.^[1][2]

What a good consultant does

• Helps you define the CMMC Assessment Scope, often shrinking it with a CUI enclave.^[3]
• Runs a gap assessment against the 110 NIST SP 800-171 Rev. 2 requirements and scores it the way an assessor would: 1, 3 or 5 points per requirement.^[3]
• Builds the System Security Plan and a realistic remediation plan. An open System Security Plan blocks even a Conditional status.^[3]
• Prepares evidence in final form; drafts do not count in an assessment.^[3]

Questions to ask

1. Are you a Registered Provider Organization? (Check the Cyber AB Marketplace yourself.)^[2]
2. How many Level 2 readiness projects have you finished for companies our size, and can we speak to one?
3. Is the price fixed for a defined scope, or hourly? What is not included?
4. Do you also run C3PAO assessments? A C3PAO must follow the Accreditation Body’s conflict-of-interest policy and record whom it has consulted for, so ask how they keep the two apart.^[3]
5. Will you hand over everything you produce, so another firm can pick it up?

Red flags

• A guaranteed pass or a promise to “certify” you.
• A price quoted before anyone has looked at your scope.
• Pressure to buy their software or managed service as part of readiness.
• No written statement of work.

FAQ

What is the difference between a CMMC consultant and a C3PAO?

A consultant (usually a Registered Provider Organization) helps you prepare. A C3PAO is the authorized assessor that conducts the Level 2 certification assessment.

Do I need a CMMC consultant?

No, if your team understands NIST SP 800-171 and has time. Many small contractors hire one for scoping, the gap assessment and the System Security Plan.

How much does a CMMC consultant cost?

It depends on scope and how much remediation you need; most firms quote per project after a scoping call. Get at least two written quotes for the same scope.
