The report summarizes the DoD's finalized CMMC 2.0 rule—effective November 10—which makes cybersecurity certification mandatory for defense contracts and affects roughly 330,000 contractors across Levels 1–3 (with Levels 4–5 still draft). It outlines assessment requirements (self-assessments, third-party audits, government-led assessments), reporting to SPRS, the scope of each level by data sensitivity (FCI/CUI), and notes offensive testing (penetration testing/red teaming) as part of future expectations while mentioning HackerOne services to help organizations comply.
