CMMC & DoD Cybersecurity Hub for Subcontractors

DoD cyber compliance starts with the information the subcontract will actually require you to handle, the systems that will handle it, and the clauses that attach to that performance.

CMMC and DFARS cybersecurity obligations can affect eligibility for award, system architecture, cloud providers, incident response, lower-tier suppliers, and representations made to the prime. The requirements should be mapped to the specific subcontract rather than treated as a generic company badge.

Use this hub to move from the basic FCI/CUI question into CMMC level selection, 7012 obligations, incident reporting, supplier representations, and lower-tier flowdown.
