The July 2026 memorandum gave three reasons. Compliance costs were prohibitive. Third-party assessors were in short supply. Regulatory timelines were complex. The Department of War said these pressures were driving small businesses out of its contracts.
A reform task force convened in early September 2026. It read more than 1,100 responses to a request for information. Its report was due to the Department of War Chief Information Officer on 11 September 2026.
The size of the program matters for planning. The regulatory impact estimate counts 1,104 contracts in year one, 5,565 in year two and 18,554 in year three. The numbers come from the Federal Register final rule of 10 September 2025. That rule reaches 337,968 entities, and 229,818 of them, 68 percent, are small entities.
| Step | Original window | What it was meant to do | Status |
|---|
| 32 CFR part 170 - CMMC 2.0 programmatic rule | Effective 16 December 2024 | Create the CMMC 2.0 program | In force |
| Phase 1 | 10 Nov 2025 - 9 Nov 2026 | DoW decides on CMMC in a solicitation | Window ended 9 Nov 2026; self-assessments still required |
| Phase 2 | 10 Nov 2026 - 9 Nov 2027 | Third-party C3PAO Level 2 assessment for CUI awards | Suspended 13 July 2026; no restart date announced |
| Phase 3 | 10 Nov 2027 - 10 Nov 2028 | Window set by the final rule | Suspended |
| Phase 4 | From 11 November 2028 | CMMC required wherever contractor systems handle FCI or CUI | Suspended |
Two points follow. The Phase 1 window ended on 9 November 2026. But the Department of War program office or requiring activity still decides. It decides whether to insert a CMMC requirement into a solicitation. Phase 4 was set for 11 November 2028 and is now suspended.
Which contract clauses keep the requirements alive during the pause?
FAR 52.204-21 applies to every contractor whose systems process, store or transmit FCI. It sets 15 minimum safeguarding controls.
The controls cover access, user and device identity, safe media disposal, physical access, communications and malicious code protection. The full set of 15 is in FAR 52.204-21 on acquisition.gov.
DFARS 252.204-7012 stays the standard for CUI work and still points to NIST SP 800-171 Rev. 2. DFARS 252.204-7021 is what puts a CMMC level into a Department of War contract. Its title is Contractor Compliance with the CMMC Level Requirements. Read DFARS 252.204-7021 on acquisition.gov.
The contracting officer picks one of four designations. They are Level 1 Self, Level 2 Self, Level 2 C3PAO and Level 3 DIBCAC. The rule took effect on 10 November 2025.
| Designation | Who performs it | Status length | Allowed now? |
|---|
| CMMC Level 1 (Self) | Self-assessment filed in SPRS | Final status 1 year | Yes |
| CMMC Level 2 (Self) | Self-assessment filed in SPRS | Final status 3 years; conditional status 180 days | Yes - the only Level 2 designation allowed now |
| CMMC Level 2 (C3PAO) | Approved third-party organization | Final status 3 years | No - removed during the review |
| CMMC Level 3 (DIBCAC) | Defense Industrial Base Assessment Center | Final status 3 years | No - suspended with Phases 3 and 4 |
Read CMMC Level 2 cost before you set aside money for tools and outside help.
Is NIST SP 800-171 Rev. 3 replacing Rev. 2 for CMMC yet?
Not yet. The CMMC Level 2 requirements in your contracts still map to Rev. 2. Rev. 3 has been final since May 2024, but most defense contracts still referenced Rev. 2 as of August 2026. Assess against Rev. 2 now and treat Rev. 3 as a forward plan.
| Measure | Rev. 2 | Rev. 3 |
|---|
| Publication status | January 2021, now superseded | May 2024 |
| Requirements in the model | 110 | 97 |
| New control families | Not applicable | Adds Supply Chain Risk Management, Planning, and System and Services Acquisition |
| Assessment procedures (one estimate) | About 320 determination statements | More than 400 |
| Control families covered | 14 | 17 |
The final NIST publication lists every change.
Compare CMMC with the cybersecurity compliance frameworks guide. If you also use the NIST Cybersecurity Framework, see NIST CSF implementation cost for enterprise 2026.
What should you do in the next 90 days?
- Keep your SPRS record current. File the self-assessment and the senior-official affirmation on time.
- Check every contract and solicitation for a designation. A third-party designation should come out during the review, so ask your contracting officer to confirm it.
- Plan against Rev. 2 for assessments and Rev. 3 for roadmaps.
- Watch for a new schedule. As of 19 October 2026 no new Phase 2 date had been announced.
In short, the July 2026 action changed the assessment method, not the CMMC Level 2 requirements. The 88-point line means you can lose at most 22 points. Requirements worth more than 1 point cannot go on a POA&M, apart from one encryption item. Self-assessments, SPRS affirmations, FAR 52.204-21 and DFARS 252.204-7012 all still apply to you. A senior-official affirmation must be no older than 1 year.
