If you saw the news about Class Deviation 2026-O0025 and thought, “Great, I don’t need a C3PAO anymore,” you aren’t alone. Contracting officers across the Defense Industrial Base are actively stripping mandatory C3PAO Phase 2 audit requirements from live solicitations and contracts.

The mandatory audit gate is paused—but the obligation to comply with NIST SP 800-171 Rev 2 is not. In fact, the shift to Level 2 Self-Assessments actually increases your direct legal and financial risk.

The Reality of Class Deviation 2026-O0025

Under the new class deviation, the Department of Defense is relying heavily on SPRS self-assessments. When your C-suite or senior executive signs off on that SPRS score, they are legally certifying to the federal government that every single NIST SP 800-171 control is accurately documented, met, or tracked in an active System Security Plan (SSP) and Plan of Action & Milestones (POA&M).

Without a third-party audit to validate your environment, the safety net is gone. An inflated or inaccurate self-assessment score enters dangerous territory under the False Claims Act (FCA) and the Department of Justice’s Civil Cyber-Fraud Initiative.

Why Mock Assessments Are More Critical Than Ever

While you may not need a formal C3PAO certification to bid on a contract today, you still need bulletproof confidence in the score you report to SPRS. That’s where a C3PAO-led Mock Assessment comes in. A mock assessment mirrors a formal C3PAO audit without the regulatory paper trail. Here is why proactive contractors are using this pause to conduct dry runs:

  • Executive Liability Protection: Validate your true score before an executive signs their name to an official government database.
  • Audit-Grade Evidence Verification: A self-assessment is only as good as its artifacts. A mock assessment tests your evidence against actual C3PAO evaluation criteria, exposing weak policies or unverified technical controls.
  • Zero-Risk Gap Identification: Uncover non-compliant controls and POA&Ms internally—before a DCMA/DIBCAC audit, whistleblower, or incident triggers a formal investigation.
  • Stay Ahead of the Curve: The Phase 2 pause is a administrative restructuring, not the end of CMMC. When third-party requirements inevitably return to contracts, your organization will already be certified-ready while competitors scramble.

The Bottom Line

The DoD removed the requirement for C3PAO certification stamps on contracts, but they didn’t reduce the technical standards. Self-certification puts 100% of the legal risk squarely on your leadership team.Don’t guess on your SPRS score. Treat your self-assessment with the rigor of a formal audit—run a mock assessment with certified assessors who know exactly what “compliant” looks like.
