Machine shops do not need perfect paperwork to support CMMC Level 1, but they do need real controls, a clear scope, and simple evidence that proves those controls are being used consistently.
CMMC Level 1 for Machine Shops: What You Actually Need to Prove
Many machine shops hear "Level 1" and assume it means a light paperwork exercise. It does not. If your shop touches Federal Contract Information, the question is whether your day-to-day controls can hold up when someone asks you to prove them.
Start with Manufacturing Cybersecurity & CMMC Readiness for the big-picture service view, then use CMMC Level 1 Readiness and CMMC Level 1 Readiness Review if you need help tightening the details.
This article is for practical readiness guidance only. It is not legal advice, and Sun Life Tech does not guarantee certification, affirmation, or contract outcomes.
We can quickly review your setup and show you what’s working and what needs improvement.

What a machine shop usually has to prove
The real issue is not whether you bought a firewall or turned on MFA once. You need to show who can access FCI, what devices touch it, how you handle offboarding, and whether your environment is being maintained in a repeatable way.
- Named user accounts instead of shared logins
- MFA for email, remote access, and admin actions
- Supported computers with patching and endpoint protection
- Basic policies for passwords, access approval, and incident reporting
- Simple evidence such as screenshots, reports, and tickets
Where small shops get stuck
Most gaps are operational, not theoretical. Shared floor PCs, forwarded drawings, unmanaged admin accounts, and vendor remote access create the kind of weak spots Sun Life Tech sees when a shop requests a CMMC Level 1 Readiness Review.
If your current setup still looks like "basic IT," compare it to this CMMC readiness checklist for fabricators and machine shops and what FCI means for machine shops.
What to do next
Define scope first, clean up identity second, and then document the small set of controls you actually rely on. If the shop floor, front office, and Microsoft 365 tenant are all mixed together, start with Manufacturing Cybersecurity Services and Manufacturing Cybersecurity Assessment.

FAQ
Quick answers to common questions.
Yes. The evidence can be simple, but you should be able to show that the controls you rely on are real, current, and used consistently.
No. Email matters, but Level 1 also touches endpoints, identity, access control, offboarding, and how FCI is handled across the business.
No. Sun Life Tech can help improve readiness, reduce gaps, and organize evidence, but no legitimate provider should promise certification or affirmation outcomes.
