CMMC vs Cyber Essentials
CMMC Level 2 · UK Cyber Essentials (NCSC) · data 2026-10-27
Requirement-level comparison of CMMC Level 2 and UK Cyber Essentials (NCSC), in both directions, derived from published crosswalks and ControlMapping's curated topics.
Of 5 UK Cyber Essentials (NCSC) requirements, 5 map to something in CMMC, 0 are only loosely related, and 0 have no mapping in our data.
Cyber Essentials certifies five technical controls only; governance, risk assessment, incident response and backup are deliberately outside its scope. All links are editorial.
