Coalfire Federal CMMC Assessment Cost: $35K to $200K+

One of the larger Cyber AB authorised C3PAOs, Coalfire Federal carries deep cross-framework experience and a structured remote-assessment workflow. This vendor profile lays out fee-band estimates by company size, the bundling opportunities, the Statement of Work levers, and the trade-offs against smaller boutique C3PAOs.

Vendor profile

Coalfire is a long-established federal cybersecurity assessment firm headquartered in Westminster, Colorado. The Coalfire Federal practice focuses on government-facing frameworks: FedRAMP, FISMA, DoD Cloud Computing SRG, HITRUST, PCI DSS, SOC 2, and now CMMC. Coalfire became a Cyber AB authorised C3PAO during the initial wave of C3PAO authorisations. The current Cyber AB Marketplace listing is at cyberab.org/Marketplace; verify Coalfire Federal authorisation status there before any engagement.

The firm's CMMC delivery sits inside a broader federal-cyber consulting business, which is the main differentiator versus boutique C3PAOs. Contractors that already hold or are pursuing a FedRAMP authorisation, a FISMA ATO, or an existing Coalfire SOC 2 engagement can sometimes combine work to reduce duplicate evidence collection. For a contractor pursuing CMMC Level 2 and FedRAMP Moderate in parallel (a common pattern for managed service providers selling to the DIB), the cross-framework efficiency is real and quantifiable.

On the staffing side, Coalfire Federal deploys named Certified CMMC Assessors (CCAs) per the Cyber AB requirement. CCAs are authorised by the Cyber AB and listed in the same marketplace. Most engagements deploy a lead CCA plus 1-2 supporting CCAs depending on assessment scope. Engagement-team continuity (the same CCAs working your account through readiness and into formal assessment) is something to negotiate in the Statement of Work; it materially reduces rework when the formal assessment begins.

Fee bands by company size

Coalfire Federal does not post per-engagement pricing publicly. The bands below are industry estimates aligned with the broader C3PAO market profile documented on the C3PAO cost page. Treat them as rough planning numbers, not Coalfire-quoted figures. The only definitive number is the one in a signed Statement of Work.

Profile	Estimated fee band	Typical timeline
Under 50 employees, single site, single CUI workload	$35K - $60K	4 - 6 months
50 - 200 employees, 1-2 sites, defined CUI scope	$55K - $90K	5 - 8 months
200 - 500 employees, multi-site, complex CUI flows	$80K - $150K	6 - 10 months
500+ employees, multi-site, complex enclaves	$130K - $200K+	8 - 12 months

Where Coalfire Federal is well-positioned

For contractors selling to multiple federal-civilian and DoD agencies, having one assessment firm carry the full framework portfolio reduces audit fatigue. A managed service provider holding FedRAMP Moderate, a HITRUST authorisation for healthcare customers, and CMMC Level 2 for DoD work can negotiate a multi-framework engagement that compresses evidence-collection labour. The cross-framework efficiency typically nets a 10-20 percent saving over running separate engagements with separate firms.

For contractors with mature security programmes that need a thorough, structured assessment workflow, Coalfire's remote-assessment competence is a fit. The firm has built tooling and process around evidence collection that works well for organisations with good documentation hygiene. For contractors with disorganised evidence libraries or weak SSP authoring, a more hand-holding boutique C3PAO may produce less friction.

Coalfire Federal also has visible adjacency to penetration testing and red-team services, which are not part of the C3PAO assessment itself but are required for Level 3 (DIBCAC) preparation. Contractors expecting to need a NIST SP 800-172 enhanced security assessment in addition to Level 2 may find the same-firm continuity useful, though there are conflict-of-interest considerations to navigate (CMMC C3PAO assessor and penetration tester for the same client should not be the same engagement team).

Statement of Work levers that move price

The single biggest fee mover is assessment boundary. A Statement of Work that defines a tight enclave (one VPC or one tenant, with documented inheritance from FedRAMP-authorised cloud services) commits fewer assessor days than one that requires the assessor to clarify boundaries on-the-fly. Pre-engagement effort on the SSP and the boundary diagram pays back at roughly 2-3x in C3PAO fee savings. Use the inheritance discussion to maximise FedRAMP-Customer-Responsibility credit; the CMMC vs FedRAMP page covers the mechanics.

The second lever is on-site versus remote days. Coalfire (and most C3PAOs) bill more for on-site days because of travel cost. A Statement of Work that maximises remote assessment (with on-site limited to a 1-3 day kickoff and findings session) typically saves $5K-$15K. The trade-off is that some controls (physical security, especially) are easier to evidence on-site. Negotiate the on-site day count based on the controls that actually require eyes-on observation rather than blanket on-site allocation.

The third lever is multi-year commitment. Some C3PAOs offer reduced rates on the year-3 triennial reassessment in exchange for a multi-year engagement booked at the time of initial certification. This can save 10-15 percent on the recurring assessment cost. Practitioner accounts suggest Coalfire Federal will entertain this conversation for engagements above the $80K initial-fee threshold.

The fourth lever is bundled gap-assessment and remediation-services scope. Coalfire Federal cannot perform the gap assessment AND the formal C3PAO assessment for the same client because of independence rules. But Coalfire Cybersecurity (the broader consulting practice, often delivered through a Coalfire sister entity) can perform gap and remediation work, then hand off to a different Coalfire team for the C3PAO engagement. Whether that bundling actually saves money depends on the specific entities involved; verify with the firm at the time of the engagement.

Alternatives worth considering

For sub-50-employee contractors with a single CUI workload, a boutique C3PAO often wins on cost-per-assurance. Boutique firms tend to come in at the lower end of the small-tier band ($30K-$40K versus $35K-$50K) and are typically more flexible on scheduling. The trade-off is brand recognition (less helpful with primes that have a preferred-vendor list) and breadth of cross-framework experience.

For mid-size contractors with multiple framework obligations, Schellman and ControlCase are direct alternatives to Coalfire Federal. Schellman has a stronger SOC 2 / PCI / ISO 27001 footprint; ControlCase has the PCI QSA heritage and a strong CMMC ramp. Both are profiled on dedicated pages: see Schellman CMMC cost and ControlCase CMMC cost.

Frequently asked questions

Is Coalfire Federal a C3PAO?

Yes. Coalfire Federal is on the Cyber AB authorised C3PAO marketplace. Coalfire is one of the longest-standing federal-cyber assessment firms, with deep FedRAMP, FISMA, and HITRUST history. The CMMC C3PAO authorisation is a relatively recent addition to that portfolio. Always verify current authorisation status at cyberab.org/marketplace before signing a Statement of Work, because authorisation can change.

How much does a Coalfire Federal CMMC Level 2 assessment cost?

Coalfire Federal does not publicly post per-engagement pricing. Practitioner reports and industry tier-band estimates suggest fees of $35,000-$60,000 for a small contractor (under 50 employees, single site, clean CUI scope), $55,000-$90,000 for a mid-size contractor (50-200 employees, 1-2 sites), and $90,000-$200,000+ for larger or multi-site organisations. These bands are estimates aligned with the broader C3PAO market on the C3PAO cost page, not Coalfire-published numbers. Always request a written Statement of Work fee.

What is Coalfire Federal good at?

Coalfire Federal carries strong cross-framework experience (FedRAMP, FISMA, PCI, HITRUST, SOC 2) which can streamline assessments for contractors who hold multiple authorisations. For contractors with an existing Coalfire engagement on another framework, adding CMMC to the engagement can produce some bundling efficiency. Coalfire also has a reputation for thorough remote-assessment workflows, which fits contractors who prefer to minimise on-site days.

How long does a Coalfire Federal engagement take?

From signed Statement of Work to certification posting, a typical engagement runs 3-6 months. The breakdown: scope-confirmation and pre-assessment readiness check (2-4 weeks), formal evidence collection and document review (4-8 weeks), assessor on-site or remote evidence sessions (1-3 weeks), draft assessment report and contractor response cycle (2-4 weeks), final report and certification submission (2-3 weeks). C3PAO scheduling backlogs in 2026 have stretched the calendar elapsed time to 6-12 months from engagement signature.

Should I pick Coalfire Federal over a smaller C3PAO?

It depends on what you optimise for. Larger C3PAOs like Coalfire bring brand recognition (useful for prime-contractor visibility) and cross-framework experience. Smaller C3PAOs can be more responsive on scheduling, more flexible on Statement of Work scope, and less expensive at the bottom of their fee bands. For sub-100-employee contractors with a single CUI workload, a smaller boutique C3PAO is often the better cost-per-assurance choice. For 200+ employee contractors with multi-site complexity or multiple framework obligations, a larger firm makes more sense.

What should I include in a Statement of Work?

At minimum: a clear definition of the assessment boundary (in-scope assets, locations, user populations), the planned use of inherited controls from any FedRAMP-authorised External Service Providers, the deliverables (draft report, final report, POA&M handling), the timeline with named milestones, the on-site day count assumed in the fee, the rate for additional assessor days if scope changes, the indemnification posture, and the escalation path for findings disputes. Get the fee broken down by phase so you can stage payment against milestones.
