The journey to CMMC Level 3 represents the highest level of cybersecurity maturity under the CMMC framework. Unlike Levels 1 and 2, which focus on FCI and CUI, respectively, Level 3 targets Advanced Persistent Threats (APTs). That means more extensive security, defined in NIST Special Publication 800-172.

For organizations that support critical programs or handle high-value assets for the Department of Defense, achieving Level 3 is imperative. But what does it take to implement the enhanced controls from NIST SP 800-172, and how do they fit into the broader CMMC ecosystem?

Under the final CMMC rule, contractors at Level 2 and above must implement formalized IR policies, procedures, and continuous monitoring capabilities to maintain compliance. Without a well-structured IR plan, organizations risk non-compliance, loss of contract eligibility, and significant security breaches.
