The image of a clean, modern plant floor with CNC machines connected by network cables—and one isolated, equipped only with a fighter jet-shaped USB drive—perfectly illustrates the shift underway in U.S. manufacturing. For machine shops pursuing Department of Defense (DoD) contracts, the road to compliance with the Cybersecurity Maturity Model Certification (CMMC) isn’t just a technical upgrade—it’s a fundamental transformation in how they operate.
Most shops today thrive on speed, flexibility, and tribal knowledge. Engineers walk over with USBs, code moves between design stations and machines with ease, and documentation is often informal or nonexistent. That era is ending.
To handle Controlled Unclassified Information (CUI)—a requirement for the majority of DoD work—shops must now embrace a compliance-first mindset. Machines that once lived on the network are now physically or logically segmented. File transfers must happen via FIPS 140-2 Level 3 validated USB devices. Every action—every file moved, every user who touches it—must be logged, justified, and reviewed.
That means more documentation. More controls. More training. And, inevitably, more time to do what once seemed simple.
But the payoff is significant.
Achieving CMMC Level 2 compliance opens the door to high-value contracts, often with less competition. It also positions shops to be trusted partners in the DoD’s evolving supply chain, where cybersecurity is no longer optional—it’s operational.
This is a disruptive change, no doubt. But it’s also an opportunity. The shops that embrace this transformation—investing in the right tools, creating a culture of security, and preparing their teams for the long haul—will not only stay in the game, they’ll stand out.
It starts with awareness. It continues with commitment. And it succeeds with execution.
In the past two years we have been unwavering in our goal. What is the fastest, easiest and best way to become CMMC compliant with the least amount of money? We believe we have found the answer!
But the biggest hurdle is managing the expectations of those who run the plant floor. A lot will change, you are doing it because you believe in securing the secrets of the US DoD.
Area |
Current State |
CMMC-Compliant Future State |
Access Controls |
General employee/shop floor access. Visitors can sometimes access sensitive areas. |
Strict access controls for CUI areas. Only authorized/trained staff permitted; tighter restrictions for visitors/third parties. |
IT Security on Equipment |
CNC machines may be on open/shared networks, minimal device hardening. |
Hardened devices—firewalls, restricted access, logging. Remote access and device software must be CMMC-compliant, often requiring tool changes. |
CNC File Transfer/Storage |
Uncontrolled file storage; easy use of cloud drives, network shares, or USB for CAD/CAM/G-code files. |
All file storage/transfer must be on access-controlled systems. Encryption, usage logging, and removable media restrictions required. |
Network Printing |
Direct job printing from any workstation/device, network printers accessible by most staff. |
Network printing not allowed. Printing only via a secure, access-controlled room. Printer must reside within this room. |
Paper Handling & Controls |
Unrestricted paper output—printouts taken anywhere, paperwork left at workstations, basic disposal. |
Paper may not leave secure print room unless in a locked clipboard/case. All paper must eventually be shredded; logs maintained. |
USB/Removable Media |
Use of USB and external drives common; can be left unattended at workstations. |
USB and paper must not be left unattended when off-shift. Removable media logs, strict policies, and secure storage required. |
Employee Training/Policy |
Awareness training ad-hoc, mostly verbal. Few signed policies; little documentation of training. |
Formal, documented policy sign-offs and training records for all staff handling CUI/DoD work; retraining tracked and auditable. |
SOPs & Auditing |
SOPs informal or undocumented; rare internal audits. |
Fully documented, updated SOPs covering data, device, and incident handling. Regular internal audits and documentation required. |
Physical Security |
Open production areas, basic building locks. |
Secure physical zones, badge access, visitor logs, possible surveillance for any CUI-handling space. |
Network Segmentation |
Single, flat network for shop, admin, and guest systems. |
Segmented networks—CUI-handling devices isolated from other systems (e.g., shop floor vs. office vs. guest Wi-Fi). |
Change Management |
Updates/patching are informal or unmanaged. |
All changes to equipment/software require documented change control, approval, and auditable logs. |
Incident Reporting |
Incidents rarely reported or documented; no formal process. |
All incidents are reported and tracked per documented response plans; logs kept for improvement and audit. |
Overhead & Time Commitment |
Little dedicated time for compliance/admin tasks. |
Ongoing maintenance—training, audits, documentation, change reviews—become routine overhead and require dedicated resources. |
Key takeaways:
-
Network printing is effectively eliminated except within a controlled print room, with very strict handling rules for any paper output.
-
Physical and operational discipline increases: Locked clipboard cases and shredding are mandatory for CUI paper. USB drives get the same protected treatment as paper—never left unattended.
-
All staff must change behaviors regarding both digital and physical information.
