CMMC Compliance for Defense Contractors


A focused guide series on the Cybersecurity Maturity Model Certification: what the levels require, what certification costs, how SPRS scoring works, and how to prepare people, process, and AI systems for assessment.

Why This Series Matters

Phase I self assessments remain while Phase II is suspended as of July 13, 2026. This series helps contractor leaders read current contract terms, scope FCI and CUI, pick the right level, build a defensible System Security Plan, and keep evidence ready between assessments.

02Scope and pick a level

Separate FCI from CUI, map where data lives, and confirm whether Level 1, 2, or 3 applies.

03Build the evidence
