What is the CMMC model and what problem does it solve?

CMMC is a maturity model that defines cybersecurity practices and assessment expectations for organizations in the DoD and DIB supply chain.

The Cybersecurity Maturity Model Certification (CMMC) model provides a structured way to define and assess cybersecurity expectations for suppliers and partners working with the Department of Defense and the Defense Industrial Base. Instead of relying on informal assurances, the model organizes requirements into maturity levels and groups them into domains, processes, and practices.

In practical terms, CMMC helps organizations understand what is expected at a given level and how to demonstrate that expectations are met. It also provides a common language for buyers and suppliers to discuss cybersecurity capability and assessment readiness within the supply chain.

Expert Insight

Organizations often underestimate the operational side: evidence, repeatability, and governance. A foundations-level understanding helps teams avoid treating CMMC as a one-time documentation project.

CMMC turns cybersecurity expectations into structured, assessable maturity levels.
