TL;DR
Phase 1 of the CMMC rollout (live since November 10, 2025) lets many contractors self-assess. That changes on November 10, 2026, when Level 2 third-party certification by a C3PAO becomes the default condition for award on applicable contracts. Certification can take 6 to 12 months to prepare for, so "we'll deal with it later" is already a risky position.
The clock that matters
The DoD's own CMMC Program FAQ lays out the timeline directly: as of November 10, 2025, applicable contractors must complete a Level 2 self-assessment to verify compliance with NIST SP 800-171 Revision 2 requirements, and beginning November 10, 2026, Level 2 third-party assessments will be required for applicable contractors. Industry analysts widely describe this as the Phase 2 milestone, the date contractors are circling in red.
Why self-assessment is a false comfort
Phase 1 self-assessment lets organizations attest to their own compliance. But the DoD has discretion to require third-party certification even during Phase 1, and once Phase 2 begins, a C3PAO assessment becomes the norm for CUI work. A self-assessment that quietly overstates your posture is exactly the gap CMMC was designed to close.
The preparation math
Most defense contractors need six months to a year to become assessment-ready, depending on their current security maturity. Work backward from a 2026 or 2027 award date, and the runway disappears quickly, especially when you factor in remediation of gaps you discover along the way.
Where 6clicks fits
The teams that clear assessments comfortably treat compliance as continuous, not a point-in-time scramble. 6clicks keeps evidence and remediation current year-round, with readiness assessments that score your gaps against your target level and Hailey-assisted recommendations to close them. Built on Sovereign GRC Infrastructure, it does this even in restricted environments where evidence can't leave the building.
