Our own SPRS self-assessment score, publicly documented step by step
110 controls
Every NIST SP 800-171 control explained in plain English in the book
Since 2002
Petronella Technology Group, Inc. has secured regulated businesses for 23+ years
What the book covers
Not a marketing brochure. A working guide you can hand to your IT lead or compliance officer and use to plan a real certification path.
All 110 NIST SP 800-171 controls
Each control translated into plain English with practical implementation notes, so you know what assessors expect before they arrive.
SPRS scoring, demystified
How the -203 to 110 scale actually works, how to compute your score honestly, and how primes read the number you post.
Levels 1, 2, and 3 compared
What changes between self-assessment and C3PAO assessment, and how to know which level your contracts actually require. Petronella Technology Group consults at all three levels.
Scoping CUI the smart way
How to right-size an enclave and avoid paying to certify systems that never touch CUI, one of the most expensive mistakes contractors make.
Who this is for
- Defense contractors and subcontractors that handle or expect to handle CUI.
- Manufacturers on the DIB supply chain seeing CMMC language in their flow-downs.
- Engineering firms and design shops serving federal agencies and primes.
- Compliance leads preparing a board conversation about CMMC budget and timeline.
- Anyone who wants the whole CMMC picture in one evening of reading instead of a hundred browser tabs.
When you finish the book and want to know where you stand today, start with our free CMMC readiness assessment or take the ten-question CMMC self-score quiz. For the full service picture, see our CMMC compliance services, and when you are ready to generate your SSP, policies, and POA&M, ComplianceArmor produces assessor-ready documentation in days, not months.
