The US Department of Defense (DoD) published the Cybersecurity Maturity Model Certification (CMMC) Final Rule on October 15, 2024, marking a historic milestone in the global cybersecurity landscape.
CMMC 2.0 went into effect on December 16, 2024, introducing a raft of modifications that Defense Industrial Base (DIB) businesses must comply with to be eligible for defense tenders. Noticeable updates include reducing the certification levels from five to three and the introduction of mandatory C3PAOs for CMMC Level 2 certification.
This article shall highlight the significant role of C3PAOs in facilitating CMMC compliance for DIB companies. But first, let’s start by understanding what these professionals are and their place in the CMMC ecosystem.
CMMC Third-Party Assessor Organizations, more commonly abbreviated as C3PAOs, are entities tasked to undertake CMMC compliance assessments on behalf of defense contractors. These independent evaluators are authorized by Cyber AB, CMMC’s official accreditation body.
Note that the CMMC Final Rule spells out a slew of security controls that DIB companies must adhere to. To maintain a competitive advantage in the DoD supply chain network, current and aspiring defense contractors must familiarize themselves with the new changes.
Working with a certified C3PAO is the surest way to keep up with CMMC’s statutory requirements.
Following the operationalization of the CMMC 2.0 in December 16, 2024, all companies bidding for defense contracts must comply with the CMMC requirements in their respective maturity levels.
Level 1 applies to defense contractors and subcontractors that handle Federal Contract Information (FCI), while the subsequent levels apply to systems that deal with both FCI and Controlled Unclassified Information (CUI).

Level 3 represents the most advanced CMMC maturity standard. Organizations seeking Level 3 compliance must provide evidence of possessing the technical competencies required to ward off aggressive cybersecurity risks.
A primary distinction between CMMC Level 2 and Level 3 relates to the approved type of assessor. While Level 2 audits must be strictly conducted by accredited C3PAOs, Level 3 evaluations are spearheaded by government-appointed assessors.
Interestingly, the DoD requires DIBs to earn CMMC Level 2 certifications before applying for Level 3 assessments. That makes C3PAO audits mandatory for companies seeking Level 3 compliance.
As with Level 2 assessments, Level 3 permits contractors to invoke a Plan of Action and Milestones (POA&Ms). POA&Ms provide a leeway for audited DoD contractors to remain operational as they move to address the identified weaknesses in the audit reports within 180 days.
However, note that only specific controls can be delayed. Besides, OSAs must meet at least 80% of the mandatory security protocols to receive conditional certification.
Undertaking C3PAO assessments isn’t only a question of ticking the boxes. It’s a significant step towards warding off cybersecurity attacks in the defense industrial base.
One critical update to the previous CMMC iteration is the insistence on compliance for both defense contractors and subcontractors.
By obligating all DIBs to undertake mandatory C3PAO audits, the DoD won’t need to worry much about attacks that happen further down its supply chain. The agency can now concentrate its efforts on averting threats targeted directly to its central information networks.

Winning Department of Defense tenders requires a great deal of planning and persistence. A huge part of the preparation entails undergoing mandatory C3PAO-assisted cybersecurity audits.
Note that CMMC compliance is a major criterion that the DoD uses when sifting through thousands of potential bidders. Ultimately, the agency will prioritize companies that are up to date on the mandatory CMMC compliance requirements.
So, while many DIBs regard C3PAOs as working solely at the behest of the Department of Defense, these assessors play an instrumental role in prequalifying companies for lucrative defense tenders.
CMMC and the Federal Risk and Authorization Management Program (FedRAMP®) are separate yet highly intertwined security protocols. While the CMMC framework requires compliance for defense contractors, FedRAMP targets Cloud Service Providers (CSPs) intending to work with the federal government.
All FedRAMP security assessments are undertaken by Third-Party Assessment Organizations (3PAOs).
So, where do C3PAOs and 3PAOs intersect?
Assume that you’re seeking CMMC Level 2 and Level 3 assessments for cloud-based systems managed externally by a CSP.
Ideally, you’d first require a 3PAO evaluation to ensure the CSP meets the minimum FedRAMP controls and then enlist a C3PAO. However, most Cyber AB-accredited C3PAOs are competent enough to audit CSPs. Working with these assessors eliminates a multi-layered auditing process, thereby accelerating CMMC certification.

CMMC third-party assessor organizations play a fundamental role in enforcing CMMC compliance for existing and aspiring defense contractors. While the recently published CMMC Final Rule obligates C3PAO-aided cybersecurity assessment for Level 2 certification, these independent auditors can help your organization achieve compliance across the other two CMMC maturity levels as well.
However, remember that cybersecurity audits are only valid if performed by authorized C3PAOs. So, insist on an independent assessor listed on the Cyber AB website.
More importantly, a C3PAO should familiarize themselves with your current cybersecurity posture and be able to audit your company based on the required CMMC maturity levels.
