What is the timeline for CMMC 2025?
The Department of Defense published the final DFARS rule on September 10, 2025, officially ending months of OIRA review uncertainty. Defense contractors now have exactly 60 days until CMMC requirements begin appearing in new DoD contract solicitations on November 10, 2025.
Verified Timeline Milestones:
- October 15, 2024: CMMC Final Rule published in Federal Register
- December 16, 2024: CMMC Program Rule (32 CFR Part 170) took effect
- December 16, 2024: Voluntary C3PAO assessments officially began
- September 10, 2025: CMMC Acquisition Rule (48 CFR Part 204) reviewed
- November 10, 2025: DoD contract requirements to begin
- 2025-2030: Phased rollout across entire defense industrial base
The compressed timeline creates immediate preparation urgency. Organizations need Level 2 certification before contract awards, requiring implementation of 110 security controls plus operational evidence collection. Assessment wait times already stretch 3-6 months as contractors rush toward compliance.
Smart defense contractors are starting CMMC preparation now rather than waiting for the acquisition rule publication. Early certification provides competitive advantage in prime contractor partnerships and positions organizations ahead of the compliance rush.
