In manufacturing environments, protecting Controlled Unclassified Information (CUI) is essential for maintaining compliance and safeguarding sensitive designs, production plans, and operational data under CMMC. Organizations must implement secure workflows to ensure that CUI related to engineering drawings, CNC programs, and production documentation is properly controlled throughout its lifecycle.

Core Requirements

When managing CUI in manufacturing, organizations must receive, process, and store sensitive information in a secure and compliant manner. Employees and outside collaborators should receive training on proper CUI handling to prevent accidental exposure and ensure consistent routing of data through secure channels.

Operational Needs

Secure workflows require the use of specialized software for design and engineering while maintaining strict control over data transfers between systems. Providing access to compliant printing solutions ensures workers who rely on paper-based instructions or plans remain within protected processes. Enabling secure data transfers to operational technology (OT) systems and shop floor equipment, such as CNC machines, is critical for keeping sensitive production information contained.

Special Considerations

Organizations should evaluate whether physical workstations or virtual desktop infrastructure (VDI) better fit their network environment and security goals. In factory settings, physical machines can sometimes offer simpler security management due to network constraints. Dedicated print networks or compliant USB-connected printers can help maintain controlled workflows when physical documents are needed. Additionally, secure file transfer methods, such as using encrypted USB drives with designated “stage laptops,” can enable isolated data exchanges without expanding exposure. If on-premises servers or workstations are part of the secure environment, physical site security measures must also meet CMMC requirements.
