CMMC Level 2 Cost — What a Small DoD Subcontractor Actually Pays

Why CMMC cost guidance is usually wrong

Cost quotes in this space tend to cluster at two unhelpful extremes. Big consultancies quote programmes that price out small shops entirely ($500k–$2M+). Local IT MSPs quote a number that doesn't reflect the ongoing operational cost they'll be running on your behalf for the next three years. Neither is honest.

Below are the four cost buckets every Level 2 budget needs, with realistic ranges for small-to-mid manufacturers.

Bucket 1: One-time readiness build-out

The work to get you from where you are today to assessment-ready. Includes:

• Scoping the CUI environment and writing the System Security Plan (SSP).
• Implementing missing controls (MFA, EDR, network segmentation, logging, etc.).
• Documenting policies, procedures, and the Plan of Action & Milestones (POAM).
• Awareness training rollout and role-based training records.
• Optional: GCC High migration (separate cost — see Bucket 3).

Realistic ranges:

• Single-site, 10–30 staff, minimal current controls: $60k–$150k.
• Multi-site or 30–75 staff, mixed current state: $150k–$300k.
• OT/ICS integration or complex CUI scope: $300k+.

If you're quoted under $50k for end-to-end Level 2 readiness on a real CUI scope, the vendor is either underestimating the work or skipping controls. Ask which controls they're marking as POAM items and what the close-out plan looks like.

Bucket 2: Ongoing managed security

What it costs to operate the controls month-over-month after readiness is complete. Includes 24/7 monitoring, endpoint detection & response, patch management, log review, vulnerability scanning, awareness training cadence, and SSP/POAM maintenance.

Realistic monthly ranges for the same shapes as above:

• Single-site, 10–30 staff: $3,500–$5,500/month.
• Multi-site or 30–75 staff: $5,500–$8,500/month.
• OT/ICS integration: $8,500–$12,000+/month.

The big specialists at this stage typically quote $10k–$25k/month, which works for a defence prime contractor but is unsustainable for a $5M-revenue job shop. Our pricing is intentionally below that range because the SMB segment is genuinely underserved.

Bucket 3: GCC High licensing

Microsoft GCC High is a government-community cloud version of Microsoft 365 with the FedRAMP High and DoD IL5 authorisations required for some CMMC scenarios. We unpack when you actually need it in our dedicated article Microsoft GCC High — Do You Actually Need It?.

Cost realities:

• Licensing premium: Roughly $40–$60 per user per month over commercial M365 equivalents (varies by SKU mix).
• Migration cost: $20k–$80k one-time for a small-to-mid shop, depending on mailbox count and data complexity.
• Annual delta at scale: 50 users = roughly $24k–$36k/year just in license premium.

If you can scope CUI out of M365 entirely (engineering-workstation-only CUI, segmented file shares), you can sometimes operate in commercial M365 with strict handling rules and skip GCC High. We help clients model both paths in the readiness assessment.

Bucket 4: The C3PAO assessment itself

A C3PAO is an independent organisation certified by the CMMC Accreditation Body to conduct Level 2 assessments. Their fees:

• Small shop, clean scope: $25k–$50k.
• Mid-size, multi-site: $45k–$80k.
• Complex or OT/ICS scope: $80k–$150k+.

C3PAOs price by complexity, days-on-site, and number of assessment objectives in scope. A well-prepared shop (clean SSP, organised evidence, rehearsed control owners) gets through faster — sometimes meaningfully so. Time spent on readiness usually pays back twice in C3PAO fees.

Recertification: Level 2 is valid for three years, with annual affirmations of continued compliance in between. Budget another C3PAO engagement in year four.

Three realistic budget scenarios

What we don't charge for

• The readiness assessment — that's free, no obligation.
• Switching costs if you already have an MSSP — we'll work alongside if it's working.
• Long-term lock-ins — month-to-month engagement, cancel anytime.
