The ideaWhat this actually is
This is a consulting practice that gets small defense subcontractors ready for CMMC, the Department of Defense's cybersecurity certification program. The rules are now in force: rulemaking finished in September 2025, the DFARS rule took effect November 10, 2025, and requirements are phasing into new solicitations, starting with self-assessed Level 1 and 2 and moving to third-party assessed Level 2 from November 10, 2026, with universal coverage by November 10, 2028. Your service is the readiness work: assessing gaps against the required controls, building remediation roadmaps, implementing fixes, and producing the documentation and evidence an assessment demands. You are not the assessor; certified assessments are done by authorized third-party organizations, and honest positioning around that line is part of the product.
The opportunityWhy this idea works
Compliance with a deadline is the strongest demand signal in consulting, and CMMC attaches that deadline to contract eligibility: defense suppliers who cannot comply lose the work. The defense industrial base includes thousands of small manufacturers and service firms with no security staff, an IT guy who visits weekly, and contracts they cannot afford to lose. Primes are pushing requirements down their supply chains ahead of the government's own phase-in, which compresses the timeline further. The technical bar filters out most competitors, and the phased rollout through 2028 means years of runway, followed by continuous compliance work that never really ends.
The openingWhy this idea is overlooked
CMMC spent years in draft form, so many IT professionals dismissed it as a program that would never arrive; it has now arrived, and the market has not caught up. The clients are unglamorous machine shops and small subs that security consultants rarely think to serve. The result is a compliance wave hitting companies that big consultancies price out of help and most small consultants have not noticed.
The buildWhat you need to build this
| You need | Why it matters |
|---|---|
| Genuine IT security competence | The controls involve real technical work (access control, configuration, monitoring); clients need implementation help, not just a checklist reading. |
| Deep CMMC framework knowledge | You must know the required controls, the assessment levels, and the phase-in dates cold; the Cyber AB Registered Practitioner credential is one way to prove baseline knowledge. |
| A fixed-fee gap assessment offer | Small suppliers fear open-ended consulting bills; a defined assessment with a defined price gets you in the door. |
| Documentation and evidence templates | System security plans, policies, and evidence collection are heavy lifts; reusable templates make engagements profitable. |
| Professional liability insurance | You are advising on compliance that affects contract eligibility; coverage for errors and omissions is essential. |
| Honest scope language | Clients must understand you prepare them for assessment; authorized third parties perform certified assessments. Blurring that line damages credibility and can create liability. |

Questions
What people ask about this idea
Is CMMC actually happening this time?
Yes. DoD completed rulemaking in September 2025, the DFARS rule took effect November 10, 2025, and requirements began appearing in new solicitations from that date. Third-party assessed Level 2 phases in from November 10, 2026, and requirements become universal by November 10, 2028.
Can I certify companies myself?
No. Certified assessments are performed by authorized third-party assessment organizations. Your role is readiness: closing gaps and preparing documentation so the client passes when assessed. Being clear about that distinction is both ethical and good marketing.
Do I need the Registered Practitioner credential?
It is not legally required to do readiness consulting, but the Cyber AB Registered Practitioner credential signals baseline CMMC knowledge and helps with credibility. Evaluate it as a marketing and education investment.
Who are the clients?
Small defense subcontractors: machine shops, electronics manufacturers, engineering firms, and service providers in prime supply chains. They must comply to stay eligible for defense work and mostly lack security staff.
What does it pay?
Gap assessments and remediation engagements run from a few thousand dollars for small Level 1 shops to much more for Level 2 environments, with continuous compliance retainers behind them. Margins are high because the product is expertise, but hedge any specific number until you have quoted real clients.
