UK Cyber Essentials vs NIST SP 800-171 Rev 3

What is the difference between UK Cyber Essentials and NIST SP 800-171 Rev 3?

UK Cyber Essentials is a other framework applying in the United Kingdom, with 36 controls across 6 domains. NIST SP 800-171 Rev 3 is a information security framework applying in the United States, with 97 controls across 17 domains. They govern different subjects, so the overlap is limited to the governance requirements they share. The mapping below shows where that is.
