NIST 800-171 Compliance Software for Manufacturers
Support NIST SP 800-171 CUI protection inside your ERP. Role-based access control, audit trails, configuration management, and traceability for DFARS and CMMC.
NIST SP 800-171 is the federal standard that defines how non-federal organizations must protect Controlled Unclassified Information (CUI) on their own systems, spanning 110 security requirements across 14 control families. It matters because if you hold a Department of Defense contract or subcontract that touches CUI, DFARS 252.204-7012 makes 800-171 compliance contractual, and CMMC Level 2 assessments now verify those same controls before award.
Sound Familiar?
CUI scattered across uncontrolled systems
Controlled drawings, specs, and supplier data live in email attachments, shared drives, and personal desktops, so when an assessor asks you to scope your CUI boundary you can't even say where the protected data is, let alone prove who touched it.
No record of who accessed which controlled record
NIST 800-171 demands access control and audit logging across the Access Control, Audit and Accountability, and Identification and Authentication families, but a paper traveler and a generic shop login can't tell an assessor which user opened a CUI-bearing work order or part revision.
SSP and POA&M maintained by hand
Your System Security Plan and Plan of Action and Milestones live in stale Word documents that drifted from how the business actually runs, so every CMMC Level 2 or DIBCAP assessment turns into a scramble to reconcile the paperwork with the real process.
Supply chain compliance you can't see
DFARS flows 800-171 down to subcontractors, but your purchasing process has no way to flag which suppliers handle CUI or require their compliance attestation, leaving the prime exposed for the whole tier below it.
Core Capabilities
Role-based access control on every record
WorkCell enforces authenticated, role-based access across parts, BOMs, routings, work orders, and quality records, with row-level tenant isolation, so access to CUI-bearing engineering and production data maps to the least-privilege and access-control requirements in 800-171 families 3.1 and 3.5.
Audit trails for accountability
Create, change, and approval events are captured on quotes, orders, BOM and routing revisions, work orders, and inspections, giving you the user-attributable activity history the Audit and Accountability family (3.3) expects an assessor to be able to pull.
Engineering change control for CUI configurations
Multi-level versioned BOMs and routings with effective dating give you engineering change control over the exact configurations that carry CUI, so a controlled drawing revision and its production baseline stay locked together instead of floating in shared folders.
Lot and serial traceability with QC hold states
End-to-end lot and serial genealogy with QC hold states and multi-location zones keeps controlled material identified and segregated from receiving through ship, supporting the media protection and physical handling expectations around CUI-bearing product.
Supplier compliance flags in purchasing
Vendor management and the PO lifecycle let you mark which suppliers handle CUI and track their attestations alongside supplier quality metrics, so the DFARS flow-down of 800-171 to subcontractors becomes visible at the requisition and PO level instead of being assumed.
Centralized records for SSP evidence
Because engineering, quality, purchasing, and production run on one system of record rather than scattered spreadsheets, the objective evidence behind your System Security Plan and POA&M comes from the live application your team already works in.

Engineering
Versioned BOMs and routings with effective dating provide engineering change control over the controlled configurations that carry CUI.
Quality
Inspection records, NCRs, and CAPA capture user-attributable quality evidence tied to the parts and lots assessors trace.
Purchasing
Vendor management and the PO lifecycle let you flag CUI-handling suppliers and track the DFARS flow-down of 800-171 down the supply chain.
Common Questions
What is NIST 800-171?
NIST SP 800-171 is a publication from the National Institute of Standards and Technology that specifies the security requirements for protecting Controlled Unclassified Information (CUI) when it resides in non-federal systems and organizations. It defines 110 requirements grouped into 14 control families, including access control, audit and accountability, configuration management, and incident response, and is the technical baseline behind DFARS and CMMC.
Who must comply with NIST 800-171?
Any non-federal organization that stores, processes, or transmits Controlled Unclassified Information on behalf of a federal agency must comply. In practice this means Department of Defense contractors and their subcontractors under DFARS 252.204-7012, as well as suppliers to other agencies whose contracts invoke the standard. The requirement flows down the supply chain, so a small machine shop building parts from a CUI-marked drawing is in scope.
What is the difference between NIST 800-171 and CMMC?
NIST 800-171 is the set of 110 security requirements you implement, while CMMC (Cybersecurity Maturity Model Certification) is the Department of Defense program that verifies you actually implemented them. CMMC Level 2 is built directly on the 800-171 controls and requires a third-party or self-assessment depending on the contract, so 800-171 compliance is the substance and CMMC is the audit and certification layer on top.
Does WorkCell make my company NIST 800-171 compliant?
No single application makes an organization 800-171 compliant, because the standard covers policies, network security, training, and physical controls well beyond any ERP. WorkCell supports the controls that touch your manufacturing data: role-based access control, user-attributable audit trails, configuration management through versioned BOMs and routings, and traceability for controlled material. It provides objective evidence for those requirements, but you still own the broader System Security Plan and the surrounding IT and process controls.
Which NIST 800-171 control families does WorkCell help with?
WorkCell most directly supports Access Control (3.1) through role-based, least-privilege access and tenant isolation, Audit and Accountability (3.3) through change and approval logging on records, Configuration Management (3.4) through versioned BOMs and routings with effective dating, and Identification and Authentication (3.5) through authenticated user accounts. It also helps with media and supply-chain handling through lot and serial traceability and supplier flagging in purchasing.
How does WorkCell support audit readiness for an assessment?
Because engineering, quality, purchasing, and production records live in one system rather than scattered spreadsheets, the evidence behind your System Security Plan and POA&M is queryable by user, part, supplier, work order, or date range. When an assessor asks who accessed a CUI-bearing record or how a controlled configuration changed, that history comes from the live application instead of a reconstruction project across shared drives.
