Only in ISO 27001 (3 controls)
Controls covered by ISO 27001 but not CMMC. Organizations using CMMC should consider supplementing with these.
Summary: ISO 27001 vs CMMC
ISO/IEC 27001:2022 and CMMC Level 2 share 46 controls in common out of 49 total. ISO 27001 uniquely covers 3 controls that CMMC does not, including Supply Chain Risk, Business Environment, Vendor Risk Mgmt. CMMC uniquely covers 0 controls that ISO 27001 does not. Together, these two frameworks cover all tracked controls. For comprehensive cybersecurity coverage, organizations often adopt both frameworks or supplement with other frameworks.
