The CEO's Guide to CMMC 2.0: What Every Defense Contractor Executive Must Know in 2026
Reviewed by Adrian Monges Rodriguez, Founder & CEO
CMMC decisions affect contracts, operations, and cybersecurity, not just IT. Executives should understand which information their organization handles, what a particular solicitation requires, and who owns the work needed to demonstrate the required status.
Current status, October 29, 2026: Phase II implementation was suspended in July 2026, while Phase I self-assessment requirements remain in place. Confirm the latest guidance and the requirements in your solicitation or contract. See the Department of War announcement and CMMC program page.
What do executives need to know?
CMMC applies to covered defense contracts and subcontracts. Level 1 addresses Federal Contract Information with 15 safeguarding requirements and an annual self-assessment. Level 2 addresses Controlled Unclassified Information using 110 NIST SP 800-171 Revision 2 requirements. Level 3 adds selected requirements and a government-led assessment for applicable programs. The required level is specified in the solicitation; not every government contract requires CMMC.
For Level 2, the solicitation specifies either a self-assessment or an independent CMMC Third-Party Assessment Organization (C3PAO) assessment. Both generally have a three-year assessment cycle and require annual affirmation. See the DoD overview.
What should leadership own?
Contract and information review. Ask contracting and program staff which clauses apply, which information is FCI or CUI, and how requirements flow to suppliers.
Scope and accountability. Identify the systems, people, facilities, and service providers relevant to the assessment. Assign internal owners and document which controls are shared with vendors.
Resources and evidence. Fund remediation, documentation, training, and ongoing operation. A System Security Plan describes the environment and how requirements are met. Assessment evidence must reflect actual practice.
Honest assessment. Establish a process for scoring, resolving gaps, and maintaining any eligible Plan of Action and Milestones. Conditional status is subject to the rule's restrictions and closeout deadlines. A senior official makes the required affirmation; inaccurate representations can have legal consequences.
Independent assessment when required. AdVran is not a C3PAO and cannot grant certification. When a contract requires a C3PAO assessment, select an authorized assessor and budget for its work separately from readiness services.
What does a practical readiness plan look like?
- Review contracts, CUI flows, and the required assessment type.
- Define the boundary and document responsibilities across internal teams and vendors.
- Assess the applicable requirements and prioritize gaps according to risk and the assessment rules.
- Implement controls, approve policies, and gather evidence that the controls operate.
- Complete the required assessment, affirmation, and any permitted closeout work.
- Continue operating controls and keep evidence current between assessments.
The schedule and cost depend on scope and existing maturity. Do not assume a particular cloud platform, a consultant, or a fixed six-month plan guarantees success.
How can AdVran help?
AdVran's CMMC readiness services include gap assessment, documentation support, managed security controls, and preparation for the assessment required by the contract. The contractor retains responsibility for its program, and independent assessors or government assessors conduct their respective assessments.
