What Is CMMC 2.0?
CMMC (Cybersecurity Maturity Model Certification) is the U.S. Department of Defense framework that requires companies in the defense supply chain to prove they protect sensitive government information. If you hold — or want — DoD contracts, CMMC is how you demonstrate your cybersecurity is up to standard.
CMMC 2.0 streamlined the original five-level model into three levels, aligned the technical requirements to existing NIST standards, and reintroduced annual self-assessments for the lowest tier. It protects two types of data: Federal Contract Information (FCI) and Controlled Unclassified Information (CUI).
Who needs CMMC? Every organization in the Defense Industrial Base (DIB) — prime contractors and subcontractors alike. If CUI or FCI flows through your systems, your contract will require a specific CMMC level. Avantcert helps DoD suppliers reach the right level efficiently and stay compliant.
CMMC 2.0 Levels: 1, 2 and 3
CMMC 2.0 has three levels. The level your contract requires depends on the sensitivity of the information you handle.
| Level | Name | Protects | Requirements & Assessment |
|---|---|---|---|
| Level 1 | Foundational | FCI | 17 basic practices · annual self-assessment |
| Level 2 | Advanced | CUI | 110 practices (NIST SP 800-171) · C3PAO third-party assessment every 3 years |
| Level 3 | Expert | CUI (high-priority) | 110+ practices plus NIST SP 800-172 · government-led assessment |
Most contractors handling CUI need Level 2, which requires an independent assessment by a Certified Third-Party Assessment Organization (C3PAO). Avantcert prepares you so that assessment is a formality, not a gamble.
CMMC Requirements: NIST SP 800-171
At the core of CMMC Level 2 are the 110 security controls of NIST SP 800-171, organized into 14 families — access control, audit and accountability, configuration management, identification and authentication, incident response, and more.
To meet the requirements you'll need a documented System Security Plan (SSP), a Plan of Action & Milestones (POA&M) for any gaps, and evidence that each control is implemented and operating. Avantcert builds this evidence package with you and maps every control to your environment so nothing is missed before the C3PAO arrives.
CUI vs FCI: What's the Difference?
CMMC exists to protect two information types, and they decide your level:
| Data type | What it is | CMMC level |
|---|---|---|
| FCI | Federal Contract Information — not intended for public release, generated for/under a contract | Level 1 |
| CUI | Controlled Unclassified Information — sensitive government data requiring safeguarding | Level 2 (or 3) |
Identifying exactly where FCI and CUI live in your systems is the first practical step of any CMMC project — and it's where Avantcert's gap analysis starts.
CMMC vs CMMI: They're Not the Same
These two are frequently confused because the acronyms look alike — but they solve different problems.
| CMMC | CMMI | |
|---|---|---|
| Focus | Cybersecurity for DoD contractors | Process & capability maturity |
| Owner | U.S. Department of Defense | ISACA / CMMI Institute |
| Result | Certification (C3PAO) | Appraisal rating (SCAMPI, Levels 1-5) |
In short: CMMC proves your cybersecurity meets DoD requirements; CMMI rates how mature your processes are. Avantcert delivers both — see our CMMI certification & appraisal services — so we can advise which (or both) your goals require.
The CMMC Certification Process
Avantcert follows a proven four-stage path to certification:
1. Gap Analysis — scope where FCI/CUI lives and assess your current state against the required level. 2. Implementation — close gaps, write the SSP, and stand up the 110 NIST 800-171 controls. 3. Internal Audit & Pre-Assessment — validate readiness and remediate findings. 4. C3PAO Assessment & Certification — the accredited third-party assessment, followed by ongoing surveillance and your next renewal.
CMMC Cost, Timeline & How to Get Certified
How long does CMMC take? For most contractors, Level 2 readiness takes 6 to 12 months, depending on your starting maturity, the size of your CUI environment, and C3PAO scheduling.
How much does CMMC cost? Cost is driven by your environment's complexity, the gap between current and required controls, and the C3PAO assessment fee — which is separate from preparation. Rather than a generic figure, Avantcert gives you a tailored estimate after a short scoping call. Request a free CMMC quote to get your number and a readiness roadmap.

CMMC Certification FAQs
What is CMMC?
CMMC (Cybersecurity Maturity Model Certification) is the U.S. Department of Defense framework that requires defense contractors to demonstrate they protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). CMMC 2.0 has three levels.
What are the CMMC 2.0 levels?
Level 1 Foundational (17 practices, self-assessment, FCI), Level 2 Advanced (110 NIST SP 800-171 practices, C3PAO assessment, CUI), and Level 3 Expert (adds NIST SP 800-172, government-led assessment).
What are the CMMC requirements?
CMMC Level 2 requires the 110 security controls of NIST SP 800-171 across 14 families, plus a System Security Plan (SSP) and a Plan of Action & Milestones (POA&M).
What is the difference between CMMC and CMMI?
CMMC is a DoD cybersecurity certification; CMMI is a process-maturity appraisal owned by ISACA. CMMC proves your security; CMMI rates how mature your processes are. They are unrelated frameworks.
Who needs CMMC certification?
Every organization in the DoD supply chain (the Defense Industrial Base) — prime contractors and subcontractors — that handles FCI or CUI. Your contract specifies the required level.
How do you get CMMC certified, and how much does it cost?
Through gap analysis, implementation of NIST 800-171 controls, internal audit, and a C3PAO assessment (Level 2). Timelines run 6-12 months; cost depends on environment complexity. Request a free quote for a tailored estimate.
