The CyberAB - CyberAB Third-Party Assessment Organization (C3PAO) - 2025-01-31

Schneider Downs is an authorized C3PAO qualified to assess and certify CMMC certification for organizations conducting business with the Department of Defense’s (DoD) program.

What is CMMC?

To enhance the protection of Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) within the supply chain, the U.S. Department of Defense (DoD) has worked with DoD stakeholders, university-affiliated research centers, federally funded centers and industry at large to develop version 2.0 of the CMMC, a process that measures the ability of organizations within the defense industrial base (DIB) sector to protect FCI and CUI.

CMMC 2.0 will add a certification element to verify implementation of cybersecurity requirements and DoD contractors storing CUI will need to be certified by a CMMC Third Party Assessment Organization (C3PAO).

CMMC is designed to provide the DoD assurance that a DIB contractor can adequately protect CUI at a level commensurate with the risk and account for flow down to subcontractors in a multitier supply chain. CMMC requirements will begin being phased into RFIs and RFPs in early 2025 and will eventually be mandatory for all.

As of January 31, 2025, the Department of Defense (DoD) has finalized the implementation framework for the Cybersecurity Maturity Model Certification (CMMC) 2.0 program. The final rule was published on October 15, 2024, and took effect on December 16, 2024. Contracts will start to include the DFARS clause requirement, meaning all DoD contractors will be required to comply with CMMC.

Any system, network, or infrastructure that stores, processes, or transmits FCI or CUI is considered in scope for CMMC 2.0. This includes:

  • Internal IT networks that handle CUI.
  • Cloud environments where CUI is stored or processed (e.g., Microsoft GCC High, AWS GovCloud).
  • End-user devices (laptops, desktops, mobile devices) that access CUI.
  • Email and collaboration tools (if used for CUI communication).
  • Subcontractors handling CUI must also meet the appropriate CMMC level.

Organizations need to define and document the boundary of their CMMC in-scope environment to ensure compliance within their System Security Plan (SSP).

For defense contractors, the consequences could be severe. If you decide to not comply or are unable to comply with the CMMC requirements, you will no longer be able to bid on any DoD contracts that include the DFARS clause.

Each DoD Request for Proposal (RFP), Request for Quote (RFQ), or Request for Information (RFI) will specify the required CMMC level for that contract.

Contracts that require CMMC compliance will reference specific Defense Federal Acquisition Regulation Supplement (DFARS) clauses, such as:

  • DFARS 252.204-7012 (Cybersecurity Requirements)
  • DFARS 252.204-7019 (SPR System Submission)
  • DFARS 252.204-7020 (DIBCAC Assessment for Medium & High Risk)
  • DFARS 252.204-7021 (CMMC Certification Requirements)

If DFARS 252.204-7021 is included, the contract will specify the required CMMC level.

There is also the way to determine by the type of information that you will be handling with this contract:

  • If your company only handles Federal Contract Information (FCI) → CMMC Level 1 is required.
  • If your company handles Controlled Unclassified Information (CUI) → CMMC Level 2 or Level 3 may be required.
  • If your company works with high-value CUI for critical national security → CMMC Level 3 is required.

The CMMC framework is closely aligned with NIST standards, as compliance with CMMC requirements necessitates adherence to NIST guidelines. DoD contractors must either perform a self-assessment or undergo a third-party evaluation to verify compliance with the relevant NIST standards outlined in DFARS clause 252.204-7012. Under CMMC 2.0, Level 2 assessments are based on the security controls in NIST SP 800-171, while Level 3 assessments incorporate both NIST SP 800-171 and a subset of advanced protections from NIST SP 800-172.

Schneider Downs is currently one of 54 Authorized C3PAOs in the nation. Schneider Downs can help with readiness and consulting services to help you prepare for your CMMC assessment. Once you are ready for your assessment, Schneider Downs can provide partner C3PAOs to conduct the assessment.

The CMMC Model Framework

The CMMC model framework categorizes cybersecurity best practices at the highest level by domains.

Each domain is further segmented by a set of capabilities and achievements to ensure that cybersecurity objectives are met within each domain. Companies will further validate compliance with the required capabilities by demonstrating adherence to practices and processes that have been mapped across three maturity levels (explained below). Within this context, practices will measure the technical activities required to achieve compliance with a given capability requirement, while processes will measure the maturity of a organizations cybersecurity processes.

CMMC Model 2.0 Levels

The CMMC model has three defined levels, each with a set of supporting practices and processes, from Level 1 that addresses basic cyber hygiene to advanced and expert Levels 2 and 3. To meet a specific CMMC level, an organization must meet the practices and processes within that level and below. Levels are described as follows:

  • CMMC Level 1The “foundational” level of CMMC compliance requires all contractors that have FCI in their contracts to implement a set of 17 basic cybersecurity practices that are required by the Federal Acquisition Regulation (FAR) 52.204-21. Organizations that fall under level one may perform an annual self-assessment of the FAR 52.204-21 controls and report there score to the Department of Defense.
  • CMMC Level 2The “advanced” level of CMMC that requires contractors that handle CUI to implement the National Institute of Standards and Technology (NIST) 800-171 framework which includes 110 practices from 14 CMMC domains. If a contractor handles sensitive CUI, the Defense Federal Acquisition Regulation Supplement (DFARS) clause 252.204-7012 requires the contractor to be level 2 certified by having a CMMC Third Party Assessment Organization (C3PAO) perform an independent assessment to validate that the contractor has fully implemented the NIST 800-171 framework.
  • CMMC Level 3The “expert” level of CMMC maturity that is required for contractors that work with critical DoD infrastructure. Organizations seeking level 3 certification will be required to comply with the NIST 800-172 framework. Level 3 contractors are also required to be accessed by the DoD directly as opposed to an independent C3PAO. Organizations will need to become certified for level 2 practices by a C3PAO prior to being assessed by the DoD for level 3.

CMMC Domains

The CMMC 2.0 model is cumulative and consists of 6 Level 1 domains and 8 additional domains for Level 2. Level 1domains originated from Federal Acquisition Regulation (FAR) 52.204.-21 and Level 2 originated from NIST SP 800-171. The domains are as follows:

Level 1:

  • Access Control (AC)
  • Identification and Authentication (IA)
  • Media Protection (MP)
  • Physical Protection (PE)
  • System and Communication (SC)
  • System and Information Integrity (SI)

Level 2 (Also contains all Level 1 Practices):

  • Awareness and Training (AT)
  • Audit and Accountability (AU)
  • Configuration Management (CM)
  • Incident Response (IR)
  • Maintenance (MA)
  • Personnel Security (PS)
  • Risk Assessment (RA)
  • Security Assessment (CA)

CMMC Timeline and Cost

The final CMMC rule was published and put into effect on December 16, 2024.

For contracts that require CMMC, you may be disqualified from participating if your organization is not certified. Given that, we expect future RFIs and RFPs will allow prime contractors subcontractors to work the cost of compliance into their bids.
