// Frequenty Asked Question

What is the Cybersecurity Maturity Model Certification (CMMC)?

The Cybersecurity Maturity Model Certification (CMMC) was developed by the Department of Defense (DoD) to enhance cybersecurity across the defense industrial base.  No longer called CMMC 2.0, it ensures that companies handling Controlled Unclassified Information (CUI) meet standardized security requirements to protect sensitive data from cyber threats.

CMMC combines cybersecurity standards and best practices into a unified model with three maturity levels, ranging from basic cyber hygiene at Level 1 to advanced cybersecurity processes at Level 3. Achieving the right CMMC certification level is mandatory for contractors seeking DoD contracts.

Do you want to learn more about the CMMC certification process, compliance strategies, and how to prepare your organization effectively? Check out more of our free CMMC resources here: Defend Your Contracts Now CMMC: DoD Compliance | Giga Green

Understanding what CMMC is and how it impacts your business is the first step toward securing your place as a trusted DoD contractor.
