About CMMC Field Guide

CMMC Field Guide is an independent publication for small and mid-sized companies in the U.S. defense supply chain. The site focuses on a narrow problem: turning changing CMMC, NIST SP 800-171, DFARS, CUI-scoping, SPRS, and evidence requirements into readable working notes.

Source-first, not vendor-first

Articles begin with primary material from NIST, Acquisition.gov, the department responsible for the CMMC program, or the National Archives CUI Registry. We use secondary material only to find questions worth investigating, not to establish the rule. This matters because CMMC rollout information can change faster than evergreen marketing pages are updated.

Who publishes the guides

Guides are reviewed against the primary sources cited on each page before publication. The publication does not claim C3PAO, legal, government, or certification-authority status. We do not attach fictional assessor credentials, government employment, customer case studies, or invented expert quotes to the material. Readers can evaluate each page from its dated source trail, the distinction between rule text and practical interpretation, and the corrections process below.

What we cover

Our scope is CMMC program status, Level 1 and Level 2 preparation, NIST SP 800-171, DFARS cybersecurity clauses, FCI/CUI scoping, external services, evidence management, SPRS/assessment currency, POA&M closeout, and practical templates. We do not publish generic cybersecurity news, penetration-testing tutorials, product rankings, or paid 'best CMMC vendor' lists.
