Understanding CMMC
What is CMMC?
The Cybersecurity Maturity Model Certification is the DoD's framework for ensuring contractors protect sensitive information
CMMC is a cybersecurity certification framework required for Department of Defense (DoD) contractors. It verifies that companies implement adequate security controls to protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI).
CMMC = The Certification
Defines WHO needs to comply, WHEN assessments happen, and HOW compliance is verified. Three levels based on data sensitivity.
NIST 800-171 = The Controls
The actual 110 security requirements. CMMC Level 2 maps directly to all 110 NIST 800-171 Rev 2 controls. This platform covers every one.
