CMMC explained simply: What defense contractors need to know going into the second half of 2026.
If you are new to CMMC or need a plain-language refresher, here it is.
The Cybersecurity Maturity Model Certification is a DoD framework designed to ensure that contractors protecting controlled unclassified information meet minimum cybersecurity standards. It is organized in three tiers.
Level 1 covers basic cyber hygiene. Organizations perform an annual self-assessment and post results to the Supplier Performance Risk System.
Level 2 covers 110 security controls from NIST SP 800-171 Rev. 2. For most defense contractors handling CUI, this is the target. Organizations must undergo either a self-assessment or a third-party assessment depending on contract requirements. Starting November 10, 2026, C3PAO-assessed Level 2 becomes mandatory in a growing number of DoD solicitations.
Level 3 covers advanced threats and is reserved for organizations handling classified information or facing the highest risk of nation-state attacks.
The critical point for manufacturers: CMMC applies to your entire supply chain position. If your customer requires it, you are required to have it. Prime contractors are already screening subcontractors for CMMC status before awarding work.
