SPRS Score Calculator for Machine Shops & Precision Manufacturers
Self-score CMMC / NIST SP 800-171 for SPRS — built for machine shops and precision manufacturers in the DIB.
Machine shops and precision manufacturers receive government and prime drawings and specifications that are often controlled technical information — and therefore CUI. Many small shops are surprised to learn they hold CUI at all, which puts them in CMMC Level 2 (NIST SP 800-171) scope.
The shop-floor question dominates: CNC machines and OT often can't run security agents yet receive program drawings. Under §170.19 those are typically Specialized Assets reviewed via the SSP — so accurate categorization keeps the assessment focused on the few IT systems that actually store and transmit CUI.
What's typically in scope for Machine Shops & Precision Manufacturers
How the five CMMC asset categories (32 CFR 170.19) usually map to your environment — scope drives which requirements apply, so categorize before you assess.
| Asset | Category | What it means |
|---|---|---|
| The PC / file share / email where drawings are received and stored | CUI | Holds CUI — assessed against all Level 2 requirements. |
| CNC / DNC / OT receiving drawings, not fully securable | Specialized | Reviewed via the SSP, not assessed against every requirement. |
| A managed IT provider for the CUI systems | Security Protection | Assessed against the capability it provides. |
| Front-office systems with no CUI, separated | Out-of-Scope | Out of scope with justified separation. |
Where Machine Shops & Precision Manufacturers teams usually focus
Common areas to shore up — your real gaps come from the assessment, not a generic list.
- Categorizing CNC/OT so the floor doesn't widen scope
- Keeping the CUI system count small
- MFA + access control on the drawing systems
- Encryption + media handling of drawings
- A lean but real System Security Plan
Which CMMC level you need
If the drawings you receive are CUI/CTI, Level 2 is the floor; FCI-only shops are Level 1. Self vs C3PAO depends on the CUI category.
Run the level-determination wizardWhat you need to know
- Your SPRS score starts at a baseline of 110 and subtracts a weighted value (5, 3, or 1) for each unimplemented requirement — it can go negative (as low as −203).
- A score of 110 is a Final self-assessment; 88–109 is Conditional with a POA&M; below 88 you can't affirm a Conditional or Final status.
- A Conditional Level 2 self-assessment is valid 180 days to close your POA&M; a Final self-assessment is valid 3 years with annual affirmations.

Frequently asked questions
- My shop just makes parts — am I in scope?
- If the drawings or specs you receive are CUI/CTI, yes. Many small shops are surprised to learn they hold CUI.
- Can I keep my CNC machines out of scope?
- OT/CNC equipment that cannot be fully secured may be Specialized Assets reviewed via the SSP rather than assessed against every requirement; equipment with no CUI and proper separation can be Out-of-Scope.
- Do I need Level 2?
- If you handle CUI, Level 2 (NIST SP 800-171) is the floor. Confirm self-assessment versus C3PAO against your contract.
- We're a small shop with no IT staff — is this realistic?
- Yes. Scope is usually small (a handful of systems), and a guided objective-level self-assessment plus a lean SSP gets many shops to a defensible score without a consultant at every step.
- Do CNC machines have to meet all 110 requirements?
- No — OT/CNC that can't be fully secured are typically Specialized Assets reviewed through the SSP, not assessed against every requirement. Correct §170.19 categorization is the key.
