CMMC Guidance
CMMCg Resource Library

Practical tools for building and maintaining a defensible CMMC program.

Nine working documents, in the order an engagement uses them. Each one is a worksheet, tracker or checklist you fill in, not an article: they are the structure CMMCg brings to a Cybersecurity Maturity Model Certification (CMMC) engagement, published so you can start before anyone quotes you for anything.

They will not replace an engagement, and they are not meant to. What they should do is make one thing obvious by the time you have worked through two of them: CMMC involves considerably more than buying security products or completing a checklist. Every document carries a resource number and a version, so you can tell which edition you are holding.

Together the nine documents walk one path: Discover, Scope, Inventory, Assess, Document, Remediate, Collect Evidence, Validate, Prepare. The library groups that path into five stages so you can find the document for where you are.

  1. 01

    Understand

    Find out what Controlled Unclassified Information you actually hold and where it moves.

  2. 02

    Scope

    Draw the boundary around the people, systems and services that touch it, and defend every exclusion.

  3. 03

    Build

    Review the 110 requirements, write the policies and procedures, and track every gap to closure.

  4. 04

    Prove

    Collect the evidence for each practice and validate that it shows what it needs to show.

  5. 05

    Prepare

    Confirm scope, documents, evidence, people and systems are ready before the assessor arrives.

Not sure where to start

Find your industry first.

The industry pages show what Controlled Unclassified Information (CUI) tends to look like in your kind of organisation, where it travels, and which of these documents to open first. See the six industries →

Worked through two of these and want the real number?

The readiness call assesses your environment rather than your recollection of it. Bring the worksheets; an engineer runs the call.

  • The requirements costing you the most points, named
  • A written summary afterward, yours to keep
