What is CMMC in Cybersecurity?
CMMC is how the Department of Defense holds its supply chain accountable for cybersecurity. Under CMMC 2.0, contractors line up against one of three maturity levels (foundational, advanced, expert) depending on whether they handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI). Most contracts above Level 1 require a certification by a CMMC Third-Party Assessor Organization (C3PAO) before award.
Why CMMC Matters for Your Cybersecurity Career
CMMC compliance is becoming a prerequisite for winning defense contracts. The defense industrial base includes over 300,000 companies, all of which need cybersecurity professionals to achieve and maintain certification. GRC analysts who specialize in CMMC can build lucrative careers in the government contracting space.
