The Cybersecurity Maturity Model Certification (CMMC) is a certification process developed by the Department of Defense (DoD) to ensure that government contractors handling controlled unclassified information (CUI) have adequate cybersecurity measures in place. The CMMC certification is important for government contractors because it is required for any company that wants to do business with the DoD. The certification process involves an assessment of a company's cybersecurity practices and controls, and a company must achieve a certain level of maturity in order to be certified. The higher the level of certification, the more stringent the requirements. This process is important because it helps ensure that government contractors are taking appropriate measures to protect sensitive information and reduce the risk of cyber attacks.
