The complete guide to understanding CMMC levels, requirements, costs, and how to get certified faster with AI-powered compliance automation.
The Cybersecurity Maturity Model Certification (CMMC) is a unified cybersecurity standard created by the U.S. Department of Defense (DoD). It requires all defense contractors to demonstrate specific cybersecurity practices to protect sensitive government data.
CMMC builds on existing standards like NIST SP 800-171 and adds a verification component — meaning contractors can no longer self-attest to compliance (for most levels). Instead, a Certified Third-Party Assessment Organization (C3PAO) must verify your security controls.
The framework protects two types of information:
17 practices based on FAR 52.204-21. Requires annual self-assessment. Designed for contractors handling only FCI.
Most small contractors start here. No C3PAO assessment needed.
110 controls from NIST SP 800-171. Most contracts require C3PAO assessment (some allow self-assessment). Required for contractors handling CUI.
This is where most defense contractors need to be. Read our Level 2 guide →
110+ additional controls from NIST SP 800-172. Assessed by DIBCAC. Only for the most sensitive programs and advanced persistent threat protection.
If you're a DoD contractor or subcontractor — or plan to become one — you likely need CMMC certification. This includes:
The required CMMC level is specified in your contract's DFARS clause (252.204-7021).
The biggest costs aren't the assessment itself — it's the preparation: gap remediation, documentation, policy creation, and technical controls implementation. Hatty AI automates the documentation and gap analysis, dramatically reducing costs.
Traditional approach: 16-30+ weeks including gap analysis, remediation, documentation, and C3PAO scheduling.
With Hatty AI: 6-14 weeks. Our AI automates gap analysis in minutes, generates your SSP and POA&M instantly, and provides continuous readiness scoring so you know exactly when you're ready.
AI scans your controls against all 110 NIST 800-171 requirements and provides a comprehensive gap report in minutes, not weeks.
Automatically generate audit-ready System Security Plans and Plans of Action & Milestones.
Real-time compliance scoring tells you exactly where you stand and what to fix next.
Replace weeks of consultant time with instant AI-powered analysis and documentation.
See where you stand in 15 minutes. No credit card required.
Level 1 self-assessment is essentially free. Level 2 C3PAO assessments cost $30,000-$100,000+. Total implementation costs (tools, remediation, consulting) can be $50K-$500K+ — but Hatty AI can reduce preparation costs by up to 80%.
The C3PAO assessment itself takes 1-2 weeks. Full preparation typically takes 16-30 weeks traditionally, or 6-14 weeks with Hatty AI's automated gap analysis and documentation generation.
If your DoD contract involves handling CUI (Controlled Unclassified Information), you likely need Level 2. Check your DFARS clause 252.204-7021 for the specific requirement. Most DoD contractors handling sensitive data need Level 2.
An SSP documents how your organization implements each of the 110 NIST 800-171 security controls. It's a required deliverable for CMMC Level 2 certification. Hatty AI generates SSPs automatically.
