On Sept. 10, 2025, the Department Defense (DoD) issued a final rule amending the Defense Acquisition Regulation Supplement (DFARS) to implement the Cybersecurity Maturity Model Certification (CMMC) program for government contractors. This final rule established a Nov. 10, 2025, go-live date for the start of phase 1 of CMMC. As we covered in our prior GT Alerts, under the four-phased implementation approach, the focus will be on Level 1 and Level 2 self-assessments in the first year; Level 2 third-party certifications in the second year; Level 3 certifications in the third year; and all contracts and solicitations will include CMMC requirements in the fourth year.
