Cybersecurity Maturity Model Certification (CMMC) standardizes cybersecurity best practices for vendors and contractors working with the U.S. Department of Defense. The good news is that vendors have until 2025 to meet these unified standards. Only 1% of companies have implemented all 110 controls from the NIST SP 800-171 standards, says one DoD official. The best way to understand the CMMC, at a basic level, is to grapple with what it augments and why. The first step for companies seeking CMMC compliance is to recognize which level they want to achieve, then decide the best steps needed to comply.
