CMMC Level 2 Certification for DoD Contractors

What CMMC Means for DoD Contractors

CMMC defines how defense contractors must protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). Organizations that handle CUI must meet CMMC Level 2 requirements, which align with the security practices defined in NIST SP 800-171 Rev. 2. Depending on the contract, organizations may be required to complete an independent assessment by a Certified Third-Party Assessment Organization (C3PAO).

Most defense contractors that handle CUI must achieve CMMC Level 2 certification.

The Department of Defense has rolled out CMMC requirements across DoD contracts, with full implementation by 11/2028. When solicitations include CMMC clauses, contractors must demonstrate compliance at the required level to remain eligible for award.

CMMC consists of three certification levels that reflect the maturity of a contractor’s cybersecurity program.

  • Level 1: Protects FCI. Validated through self-assessment.
  • Level 2: Applies to contractors handling CUI. Requires full NIST SP 800-171 implementation and may require independent certification by a C3PAO.
  • Level 3: Applies to a limited set of high-risk programs. Assessed by the U.S. government.


Path to CMMC Certification

Defense contractors typically progress through the following steps before achieving CMMC Level 2 certification.

Level 2 of the CMMC includes all the 110 requirements from NIST 800-171, verbatim. CISO Global can perform a NIST 800-171 gap analysis – a great starting point to determine if you are meeting the CMMC requirements.

With nearly two decades of experience in multiple certification frameworks, CISO Global can provide you with the skills and a roadmap necessary to prepare for CMMC compliance, saving your company time and money. 

CMMC Core Services

CISO Global and TalaTek support defense contractors preparing for CMMC Level 2 certification through readiness services, advisory support, and official assessment. As an authorized Certified Third-Party Assessment Organization (C3PAO), we conduct formal CMMC Level 2 assessments. Or we can provide advisory services to help organizations prepare. Our team evaluates your environment against the security practices in NIST SP 800-171 Rev. 2 to identify compliance gaps and support your path to certification.

Maintaining CMMC Compliance

CMMC Level 2 certification is valid for three years and requires ongoing monitoring, documentation, and annual affirmation of compliance.

Organizations must demonstrate that required security controls remain implemented and effective throughout the certification period.

FAQs

The Cybersecurity Maturity Model Certification (CMMC) is a cybersecurity framework, established by the U.S. Department of Defense (DoD) to protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). It requires organizations in the Defense Industrial Base (DIB) to implement specific cybersecurity practices and demonstrate compliance at the level required by their DoD contracts.

The required CMMC level depends on the type of information your organization handles and the requirements in your DoD contract.

  • Level 1: For organizations handling Federal Contract Information (FCI). Validated through self-assessment.
  • Level 2: For organizations handling Controlled Unclassified Information (CUI). Requires implementation of NIST SP 800-171 controls and may require certification through a C3PAO assessment.
  • Level 3: Applies to a small number of high-risk programs and is assessed by the U.S. government.

Most defense contractors that handle CUI will need CMMC Level 2.

NIST SP 800-171 defines the security controls required to protect Controlled Unclassified Information (CUI).

CMMC uses those same controls but adds a certification process that requires organizations to demonstrate compliance through assessments.

For most contractors handling CUI, CMMC Level 2 aligns with the 110 controls in NIST SP 800-171.

A CUI boundary defines the systems, networks, and environments that store, process, or transmit Controlled Unclassified Information. Establishing a clearly defined boundary determines which systems must meet CMMC security requirements and be included in an assessment.

A C3PAO assessment is required when a DoD contract specifies CMMC Level 2 certification through independent assessment. In these cases, contractors must complete a formal evaluation conducted by a Cyber AB–authorized C3PAO to verify implementation of required cybersecurity controls.

Independent CMMC Level 2 certification assessments are conducted by Cyber AB–authorized Certified Third-Party Assessment Organizations (C3PAOs).

CMMC compliance is maintained on a three-year certification cycle. For CMMC Level 2, organizations must complete a certification assessment every three years and submit annual affirmations confirming that required security controls remain implemented and effective.

Maintaining compliance requires ongoing documentation, monitoring, and evidence management to demonstrate that security practices continue to meet CMMC requirements throughout the certification period.
