In plain terms

If you supply the US defense industry you must prove your cybersecurity to an independent assessor. The cost depends almost entirely on how much of your business is in scope, so we start by confining the sensitive information to a small, well-defined area — then fix the gaps and prepare the evidence for assessment.

Most CMMC programs cost far more than they need to because the enclave was never scoped. Every system in scope is a system that must be assessed, evidenced and maintained — so the highest-leverage work happens before any control is implemented.

Scope of this service. CerbaCore performs scoping, architecture, remediation and evidence engineering, and supports you through assessment. Certification is awarded by an authorized C3PAO — we are not an assessor and cannot certify our own work.

Scoping first, always

CMMC applies to systems that process, store or transmit controlled unclassified information. If CUI is allowed to spread across the general corporate network, the assessment boundary becomes the whole company. Pull CUI into a defined enclave and the assessable footprint may be a fraction of that.

This single decision drives the cost of everything downstream — remediation, assessment, and every year of maintenance afterwards. It is where we start.

The program

  1. CUI discoveryWhere CUI actually lives today, including the file shares and inboxes nobody declared. This step routinely surprises people.
  2. Enclave designA boundary that holds CUI and as little else as honestly possible, with the data flows in and out defined and enforced.
  3. Gap assessmentAll 110 NIST SP 800-171 controls against the real architecture, scored honestly. An assessment that tells you what you want to hear costs you at the C3PAO.
  4. RemediationSequenced by assessment risk and cost, with the controls that gate certification done first.
  5. Evidence engineeringAutomated collection so demonstrating a control operated across a period is a report, not a scramble.
  6. Assessment supportSSP and POA&M prepared, artifacts mapped control by control, and we stay in the room to answer assessor findings.

On plans of action

A POA&M is a commitment with a deadline, not a parking space. We will not write one for a control that has no funded path to closure — we would rather have the difficult conversation before the assessment than have it become a finding.

Compliance engineering covers NIST SP 800-171 outside the CMMC context, plus FIPS 140-3 cryptographic boundary work. Federal and defense covers the wider program context.

Why CMMC exists and what it gates

The Cybersecurity Maturity Model Certification is mandated by the US Department of Defense to verify that companies in the Defense Industrial Base actually protect the government information they hold. It replaced self-attestation because self-attestation was not working.

It is a gate on revenue, not a best-practice badge

Without the level your contract requires, you cannot view, bid on or win the work. CMMC is enforced through the contract vehicle itself, which is why the deadline that matters is your next recompete — not a general compliance calendar.

FCI and CUI — the distinction that sets your level

Federal Contract Information compared with Controlled Unclassified InformationFCI is non-public information generated under a government contract and maps to CMMC Level 1; CUI is sensitive information requiring safeguarding under law and maps to Level 2 or 3.all CUI is protected information — not all protected information is CUIFCI — Federal Contract InformationProvided by or generated for the governmentunder a contract, not intended for release.e.g. delivery schedules, process documents→ CMMC Level 1CUI — Controlled Unclassified InformationSensitive information requiring safeguardingunder law, regulation or government policy.e.g. technical drawings, specifications→ CMMC Level 2 or 3WHY IT DECIDES YOUR COSTLevel 1 is a self-assessment you can run internally. Level 2 requires an independent assessor, evidence and a three-year cycle.
Establishing which of the two you actually hold is the first question in any CMMC engagement, and it is answered by inspection, not by assumption.

Two categories of government information trigger CMMC, and confusing them is the most expensive early mistake we correct.

  • Federal Contract Information (FCI) is information provided by or generated for the government under a contract and not intended for public release — delivery schedules, process documentation, correspondence. Holding FCI alone puts you at Level 1.
  • Controlled Unclassified Information (CUI) is sensitive information that law, regulation or government-wide policy requires be safeguarded — technical drawings, specifications, engineering data. Any CUI moves you to Level 2 or above.

All CUI is protected information; not all protected information is CUI. Determining which you hold is done by inspecting your data, not by asking the contracts team what they assume.

The three levels of CMMC 2.0

The three CMMC 2.0 levelsLevel 1 Foundational covers 15 practices for Federal Contract Information with annual self-assessment; Level 2 Advanced covers the 110 NIST SP 800-171 controls for Controlled Unclassified Information assessed by a C3PAO every three years; Level 3 Expert adds NIST SP 800-172 and is assessed by the government.the level is set by your contract and by what information you handleLevel 1 — Foundational15 practicesFCI onlyannual SELF-assessmentLevel 2 — Advanced110 controlsNIST SP 800-171protects CUIC3PAO every 3 yearsLevel 3 — Expertadds NIST SP 800-172APT-resistantassessed by DIBCACTHE DECIDING QUESTIONDo you handle CUI, or only FCI? FCI alone is Level 1 and you assess yourself. Any CUI means Level 2 and an independent assessor.
Most of the Defense Industrial Base lands on Level 1 or Level 2. Level 3 is a small population of programs handling the most sensitive work.
LevelNameControlsProtectsAssessed byFrequency
1Foundational15 practicesFCI Yourself — self-assessmentAnnual

3Expert110 + selected NIST SP 800-172CUI on the most critical programs The government (DIBCAC)Every 3 years

Level 3 exists specifically to resist Advanced Persistent Threats — well-resourced, patient attackers, typically nation-state, who are targeting a named program rather than scanning for easy prey. The extra NIST SP 800-172 controls assume the adversary will get in and focus on limiting what they achieve.

Scoping is the whole game

CMMC enclave scoping, before and afterControlled unclassified information spread across all systems makes the whole company the assessment boundary; consolidating it into a defined enclave shrinks the boundary to a subset.this decision is made once and every downstream cost scales from itBefore — CUI everywhereassessment boundary = the whole company110 controls × every systemscopeAfter — CUI in an enclaveassessment boundary = the enclaveenclave110 controls × a defined subset
Scoping is the highest-leverage hour in a CMMC program, and it happens before any control is implemented.

What each scoping decision costs

ApproachIn-scope systemsAssessment effortAnnual maintenance
CUI everywhere (no enclave)Entire estateHighestEvery system, every year
Segmented enclaveEnclave + shared servicesModerateBounded and predictable
Fully isolated enclave / VDIEnclave onlyLowestSmallest, but users complain most

The third option is cheapest to assess and hardest to live with. We scope to what your people will actually use, because an enclave users route around is worse than no enclave — CUI ends up outside the boundary and outside your knowledge.

Asset categories, and why they matter

CategoryDefinitionAssessment impact
CUI assetsProcess, store or transmit CUIAll applicable controls, fully assessed
Security protection assetsProvide security to the enclave (SIEM, IdP, EDR console)Assessed — these are in scope even outside the boundary
Contractor risk managedCould access CUI but are policy-restrictedDocumented, limited assessment
Specialized assetsOT, test equipment, IoTDocumented in the SSP, not fully assessed
Out of scopePhysically or logically incapable of reaching CUINot assessed — must be provable

The category people miss is security protection assets. Your EDR console is in scope even if it holds no CUI, because compromising it compromises the enclave.

What a full CMMC engagement covers

PhaseWhat it produces
Gap analysis and readiness assessment Your current posture scored against every applicable control, with gaps, vulnerabilities and an honest readiness verdict. Not a score designed to make you feel prepared.
Remediation and implementation The engineering itself — secure file sharing, multi-factor authentication, log monitoring and retention, encrypted storage, and where it fits, a secure cloud enclave that holds CUI away from the rest of the business.
Documentation System Security Plan describing the boundary and each control's implementation, and a Plan of Action and Milestones tracking every unresolved gap with a dated commitment.
Policy and process Company-wide security policies, an incident response plan, and security awareness training — all three are assessed, and all three are commonly left until the last month.
Assessment support Evidence mapped control by control, and we stay in the room to answer assessor findings.
Where we stop. CerbaCore performs preparation, engineering and evidence work. The independent assessment is performed by a C3PAO, and Level 3 assessments are performed by the government. A firm cannot both prepare you and certify you — that is a conflict of interest, and any provider offering both should be treated with suspicion.

Worked example — 85-person machine shop, Level 2 required

Starting position: CUI in engineering drawings on a shared drive open to all staff. No IdP. Local administrator on every workstation. One IT contractor, two days a week.

  1. Reality checkFull 110-control compliance across the whole estate was beyond both budget and staffing. We said that in week one rather than selling a program that would fail at assessment.
  2. EnclaveA VDI pool for the 12 engineers who touch CUI. Drawings moved in; the shared drive sanitized and monitored to prevent regrowth.
  3. Shared servicesCloud IdP with phishing-resistant MFA, and a managed EDR console — both correctly categorized as security protection assets and assessed.
  4. In-scope countFrom 85 workstations and 6 servers down to 12 VDI sessions, 2 servers and 3 security protection assets.
  5. ControlsOf 110, seventy-one were satisfied by the VDI platform and IdP configuration. Twenty-two needed policy and process. Seventeen needed engineering work.
  6. POA&M disciplineThree items went on a plan of action with funded closure dates. We refused to write a fourth for a control with no funded path — it would have become an assessment finding, and the difficult conversation was cheaper in month three than in month eleven.
  7. OutcomeAssessed at Level 2. Annual maintenance is bounded because the boundary is small and the evidence collection is automated.

What a CMMC consultant should and should not do

CMMC consulting is a crowded market and the quality spread is wide. A CMMC compliance consultant adds value in scoping, architecture and evidence engineering. They cannot certify you — that is the C3PAO — and any firm implying otherwise has a conflict of interest worth walking away from.

A good CMMC consultantA warning sign
Starts with CUI discovery and scopingStarts by selling a tool
Scores your gaps honestly, including the painful onesReports you are "90% compliant" in week two
Refuses to write a POA&M with no funded closure pathPuts everything unresolved on a plan of action
Is independent of your assessorOffers to both consult and certify
Leaves you able to maintain the evidenceBuilds a dependency on their platform

For CMMC Level 2 compliance specifically, the deciding factor is almost always enclave scope rather than control sophistication. Most Level 2 programs that run over budget did so because scoping was never done, not because a control was hard.

Timeline and where time actually goes

PhaseTypical durationMost common overrun
CUI discovery3–6 weeksCUI found somewhere nobody expected
Enclave design and build6–10 weeksUser workflow objections
Migration and sanitization4–8 weeksLegacy file shares with unclear ownership
Gap remediation3–6 monthsItems needing capital approval
Evidence automation4–6 weeksCan start earlier; usually left too late
Assessment scheduling2–6 months waitC3PAO availability — book early

That last row is the one that breaks contract deadlines. Assessor capacity is constrained; book the slot before remediation finishes, not after.
