100,000 Companies Need CMMC. Only 100 Assessors Can Help.
The Defense Department says more than 100,000 companies in the defense industrial base will need a third-party CMMC assessment — and only about 100 assessors are approved to perform them. Waiting for an opening is not a strategy. Readiness is.
How many companies actually need a CMMC assessment, and how many assessors can perform one? By the Defense Department's own account, more than 100,000 companies in the defense industrial base will need a third-party CMMC assessment, and only around 100 assessors were approved to perform them, as reported by DefenseScoop from DoD's own leadership as of July 2026. That is roughly one assessor for every thousand companies that need one — and it is exactly why CMMC readiness has to start well before you ever call an assessor.
The practical answer is not to wait for an assessor to become available. It is to do your readiness work now, so that when a contract requires certification you are already prepared and in line, not just starting.
Key Takeaways
- The Defense Department reports more than 100,000 companies in the defense industrial base will need a third-party CMMC assessment, with only about 100 approved assessors as of July 2026 — roughly a 1,000-to-1 ratio, per DefenseScoop.
- Most contractors handling CUI fall under CMMC Level 2, which for many requires a third-party assessment rather than self-attestation.
- CMMC readiness follows four steps — gap assessment, closing gaps, documentation, and scheduling — none of which require an assessor to begin.
- An enclave can shrink what has to be assessed by walling CUI into one bounded, hardened environment, often the fastest readiness accelerator for small contractors.
- Simpatico is a Registered Provider Organization (RPO) that prepares contractors for assessment; the assessment itself is performed independently by a certified C3PAO.
What Does CMMC Readiness Actually Mean?
CMMC readiness is the work you do before an assessor ever shows up: understanding which level applies to you, mapping your current security against the required controls, closing the gaps, and documenting everything so it can be verified. Done well, it turns the assessment itself from a gamble into a formality. None of it requires an assessor. All of it requires starting.
Which CMMC Level Applies To You?
Most defense contractors that handle controlled unclassified information (CUI) are looking at CMMC Level 2, which aligns to a defined set of security requirements and, for many companies, calls for a third-party assessment rather than a self-attestation. Knowing your level is the first thing an honest readiness review establishes, because it determines everything that follows: the controls you need, the documentation you need, and whether an independent assessor is in your future at all.
Why Does The Assessor Bottleneck Make Waiting Expensive?
When demand for assessments outruns the supply of assessors by roughly a thousand to one, the queue starts to decide who can bid. If a contract requires CMMC and you are not ready, you do not get more time. You get passed over, and the work goes to a competitor who prepared earlier. The contractors doing readiness work now are not just compliant sooner. They are eligible sooner, while everyone else is still waiting for an appointment.
What Is The CMMC Readiness Sequence?
Four steps, in order:
Gap Assessment
Establish where your current security actually stands against your required level. Not where you believe it stands: where the evidence says it stands.
Close The Gaps
Fix the shortfalls in priority order, before an assessor is in the room. This is where most of the real work lives.
Document
Build the evidence an assessor needs to verify, not just claims. In an assessment, undocumented security might as well not exist.
Schedule
Get in line for assessment from a position of readiness rather than scrambling when a contract forces the issue.
Where Does An Enclave Fit Into This?
For many small contractors, the single biggest readiness accelerator is shrinking what has to be assessed in the first place. An enclave walls your CUI into one bounded, hardened environment so the requirements apply there rather than across your whole company. We explain the approach fully in our enclave guide, and how it compares to a whole-environment move. If your defense work is a fraction of your business, scope reduction is usually step zero.
What If You Have Already Passed A Readiness Review Before?
Readiness is not a one-time event, because your environment does not hold still. New hires, new systems, and new contracts all move CUI around. If your readiness work is more than a year old, treat it as a starting point to re-verify rather than a certificate to lean on. Passing an audit and staying defensible are different things, a distinction our team has written about before.
Who Should You Trust To Help?
Someone whose role in the ecosystem you can verify. Simpatico Systems is a Registered Provider Organization (RPO) with the CMMC accreditation body, and we act as the compliance consulting partner through the whole process: scoping, gap work, documentation, and assessment preparation.
One thing to understand about the model, because it protects you: the final assessment is performed by an independent certified third party assessor organization (C3PAO) that evaluates compliance and reports the results, not by the consultant who prepared you. That separation is deliberate. Be wary of anyone who offers to be both.
RPO — The Readiness Partner
Handles scoping, gap work, documentation, and assessment preparation. This is the role Simpatico plays for you, start to finish.
C3PAO — The Independent Assessor
Performs the actual evaluation and reports the results. By design, this is never the same organization that prepared you.
What Should A Small Contractor Do This Quarter?
Get the gap assessment done. It is the one step that costs the least, unblocks everything else, and tells you the true size of your project instead of the feared size.
