CMMCManufacturers in the defense supply chain face unique CMMC challenges — CUI lives not just on office computers but on shop floors, in CAD systems, and across manufacturing equipment. Achieving compliance requires bridging the gap between IT security and operational technology.
Manufacturing equipment and industrial control systems increasingly connect to IT networks, expanding the CUI scope to the shop floor.
Older CNC machines, PLCs, and manufacturing systems may not support modern security controls like encryption or access management.
Training machinists, fabricators, and shop floor workers on CUI handling alongside office staff requires different approaches.
Securing manufacturing facilities, controlling visitor access to areas where CUI is visible on screens or work orders.
CUI-containing work orders, drawings, and specifications displayed or stored on shop floor without adequate access controls.
Manufacturing networks not properly segmented from the general business network, expanding the CUI boundary unnecessarily.
Uncontrolled use of USB drives to transfer CAD files and programs to CNC machines without encryption or tracking.
Including preparation, tooling, and assessment fees
Depending on current maturity and scope
Manufacturers often face higher CMMC costs due to the complexity of securing OT environments alongside IT systems. Network segmentation to isolate shop floor CUI can be a significant investment but dramatically reduces ongoing compliance scope. Many manufacturers benefit from managed security services to supplement limited in-house IT staff.
