CROSSWALK MAPPINGVerified Data

Mapping ISO/IEC 27001 to CMMC 2.0

A practitioner-grade, domain-level crosswalk between ISO/IEC 27001 and CMMC 2.0. Understand how these compliance standards overlap to streamline your audit programs.

Basis for Alignment

Defensible domain-level alignment based on substantial topical overlap between ISO/IEC 27001 Annex A and NIST SP 800-171 (which CMMC Level 2 adopts as its practice set). This is not a citation to a single current, official one-to-one crosswalk table, so treat it as directional guidance, not an equivalence claim.
