ITAR compliance software and CMMC compliance software are moving from back-office concern to commercial gatekeeper. For US aerospace and defense suppliers, the question is no longer whether compliance work exists somewhere in the company. It is whether the systems used to run production can prove who accessed controlled data, what changed, which parts moved, which suppliers touched the order, and which records support the contract.

That is where many manufacturers get stuck. Compliance lives in policies, binders, SharePoint folders, spreadsheets, and security tools, while the actual work moves through ERP, purchasing, production, quality, shipping, and supplier conversations. When those two worlds do not connect, compliance becomes a reconstruction exercise.

This article looks at what International Traffic in Arms Regulations (ITAR) and Cybersecurity Maturity Model Certification (CMMC) require at the operational level, then turns that into a practical ERP standard for manufacturers that need access controls, traceability, audit history, and evidence without turning the ERP project itself into a compliance project.

Why ITAR and CMMC are becoming operational requirements

Aerospace and defense compliance used to feel like a specialist subject. Legal handled export control, IT handled cybersecurity, quality handled traceability, and operations kept the factory moving.

That separation is harder to maintain now. Prime contractors and government buyers increasingly expect suppliers to prove that controlled information, controlled parts, production records, and cybersecurity practices are handled inside the normal operating flow.

ITAR and CMMC do not ask the same thing. ITAR is about export control for defense articles, defense services, and related technical data. CMMC is about cybersecurity assurance for defense contractors and subcontractors handling federal contract information (FCI) or controlled unclassified information (CUI).

But inside a manufacturer, the operational symptoms overlap. Both create pressure around access, identity, documentation, audit trails, supplier control, evidence, and the ability to show what happened without rebuilding the story by hand.

ITAR in manufacturing: control the article, the data, and the access

ITAR applies to defense articles, defense services, and technical data controlled under the US Munitions List. For manufacturers, that can include physical parts and the technical information required to design, develop, produce, manufacture, assemble, repair, test, maintain, or modify those articles.

The operational point is simple: ITAR is not limited to shipping a part across a border. A controlled drawing, work instruction, routing note, inspection file, supplier packet, or engineering change can carry export-control risk if the wrong person gets access to it.

Under 22 CFR Part 122, US manufacturers of defense articles generally need to register with the Directorate of Defense Trade Controls, even if they do not export. Registration is not an export license, and it does not grant export rights by itself. It is the starting point for being known to the US government as a party involved in defense manufacturing activity.

The same part of the regulation also matters for ERP design. Registrants must keep records on the manufacture, acquisition, and disposition of defense articles and technical data. Electronic records need to be reproducible, readable, and protected so changes show who made them and when.

That is a very concrete software requirement. If an ERP lets users overwrite controlled records without a change history, store technical data outside access rules, or move ITAR-marked items through purchasing and production without export-control context, the system is making compliance harder than it needs to be.

ITAR also makes unauthorized exports, retransfers, and furnishing defense services without required approval unlawful under 22 CFR Part 127. For daily operations, that pushes manufacturers toward tighter control over who can see controlled data, which supplier receives which packet, what gets shared externally, and whether every disclosure has a defensible basis.

CMMC in manufacturing: protect FCI and CUI where work happens

CMMC is different in that it is not export control. It is the Department of Defense's assurance model for verifying that contractors and subcontractors have implemented required cybersecurity standards for systems that process, store, or transmit FCI or CUI.

The official CMMC program page defines three assessment levels. Level 1 covers basic safeguarding of FCI, Level 2 covers broader protection of CUI and is aligned with 110 security requirements in NIST SP 800-171 Revision 2, and Level 3 adds higher-level protection for CUI against advanced persistent threats.

The timing matters too. CMMC phased implementation began on November 10, 2025. Phase 1, running from November 10, 2025 to November 9, 2026, focuses mainly on Level 1 and Level 2 self-assessments, while later phases add more certification requirements.

For manufacturers, CMMC becomes practical in the systems where contract and production information actually sits. CUI may appear in drawings, specifications, inspection records, work instructions, quality files, supplier communications, production notes, and order documents. If those records live in the ERP, the ERP becomes part of the environment that needs to be scoped, protected, or deliberately segmented.

That does not mean the ERP alone makes a company CMMC compliant. CMMC includes policy, people, devices, networks, incident response, training, identity management, media protection, and other controls. But if the ERP is central to production and stores CUI, it has to support the company's cybersecurity program instead of becoming an exception.

What ITAR and CMMC mean for ERP requirements

An ERP does not replace export counsel, a CMMC assessor, or a security program, but it should make operational evidence easier to produce because the evidence is created as work happens:

1. Controlled item and data classification

The ERP needs a way to mark controlled parts, documents, orders, customers, contracts, suppliers, and work instructions. A single note field is not enough.

Manufacturers should be able to identify whether an item or record is ITAR-controlled, CUI, export-controlled under another regime, customer-restricted, or subject to supplier flowdown requirements. That classification should travel with the operational record: from sales order to bill of materials, routing, work order, purchase order, quality inspection, shipment, and archive.

The test is whether the system can stop someone from treating a controlled order like a normal job. If the ITAR or CUI label disappears once planning creates a manufacturing order, the ERP is not carrying the compliance context far enough.

2. Role-based and attribute-based access control

ITAR and CMMC both raise the access-control bar, though for different reasons.

For ITAR, the manufacturer may need to restrict technical data to authorized US persons or to people covered by the relevant authorization. For CMMC, the company needs to control access to FCI and CUI according to its security policies and assessment scope.

Your ERP should support least-privilege access by role, site, team, document type, order type, project, customer, supplier, and control status. It should also work with the identity controls the company already uses, including single sign-on, multi-factor authentication, and user lifecycle management.

The middle ground is where many systems fail. They can restrict a whole module, but not a specific drawing. They can hide a customer record, but not the attachment on a purchase order. They can control employees, but not supplier portal access. For aerospace and defense suppliers, that is not enough.

3. Traceability across parts, lots, serial numbers, revisions, and suppliers

Compliance evidence depends on traceability. The ERP should know what was made, from which materials, against which revision, by which operation, inspected by whom, released under which approval, and shipped to which destination.

For aerospace and defense manufacturers, traceability should cover:

Part numbers, lots, batches, and serial numbers.
Bill of materials versions and engineering revisions.
Manufacturing orders, routings, and operation history.
Material receipts, supplier certificates, and supplier lots.
Quality inspections, nonconformities, dispositions, and corrective actions.
Shipping records, export documents, and delivery evidence.

This is where compliance software and manufacturing software often diverge. A standalone compliance tool can store documents, but the ERP has to connect those documents to the real production chain. If a buyer asks which supplier lot went into a shipped serial number, the answer should not depend on someone manually searching email, a spreadsheet, and three folders.

Audit trails should be boring, complete, and hard to bypass

Audit trails become useful when they are built into normal work. They should show who created, viewed, changed, approved, released, printed, downloaded, exported, or shared controlled records, with timestamps and the previous value when a record changes.

For ITAR, records need to be maintained in a way that shows changes, who made them, and when. For CMMC, audit and accountability are part of the security control families tied to protecting CUI under NIST SP 800-171.

The ERP should make audit history boring: complete enough to trust, easy enough to retrieve, and available before an incident turns it into urgent forensic work.

That means users should not be able to erase the trail by editing a PDF manually, replacing an attachment, changing a routing after completion, or exporting controlled data without the system recording the action. The moment the audit trail depends on good habits outside the ERP, the company has a weaker story to tell.

Supplier and subcontractor flowdown belongs in the ERP

Most aerospace and defense manufacturers do not produce every part, treatment, or operation internally. Outside processing, special processes, finishing, inspection, machining, testing, logistics, and engineering support may all involve suppliers or subcontractors.

The ERP should help control what flows to those partners. At minimum, it should answer:

Which suppliers are approved for controlled work?
Which supplier contacts are authorized to receive controlled information?
Which purchase orders include ITAR, CUI, customer, or contract flowdown terms?
Which documents were sent, when, by whom, and through which channel?
Which supplier certificates, inspection reports, and acknowledgements came back?
Which suppliers touched a specific serialized part or lot?

This is one of the fastest ways to see whether an ERP is actually ready for defense supply chains. If supplier control lives in procurement notes and compliance files while purchase orders move separately, the company will spend too much time stitching evidence together.

Quality records need to prove both conformance and control

Quality management is not separate from ITAR and CMMC readiness. In aerospace and defense work, inspection records, nonconformities, corrective actions, concessions, and release approvals are often part of the evidence chain.

The ERP should connect quality events to the controlled item and its production context. A nonconformity should point to the serial number, lot, operation, revision, work center, supplier, disposition, approver, and affected customer order. A corrective action should connect back to the records it addresses. A certificate of conformance should be generated from controlled data, not manually assembled from whatever the team can find.

This is also where precision traceability matters commercially. Buyers want confidence that a supplier can manufacture the part and prove the part's history without slowing every order down.

What to ask ERP vendors before trusting them with ITAR and CMMC work

A vendor does not need to promise that their ERP "makes you compliant." In fact, be careful if they do. A stronger vendor can show how the system supports the controls, records, and evidence your compliance program needs.

Ask practical questions such as:

Can controlled items, documents, customers, orders, suppliers, and work instructions be classified in the system?
Does that classification carry through planning, purchasing, production, quality, inventory, logistics, and archive?
Can access be restricted below the module level, including specific documents, attachments, projects, orders, or supplier records?
Does the ERP support SSO, MFA, role management, and user deactivation workflows?
Can the system show who viewed, changed, approved, exported, downloaded, or shared a controlled record?
Are record changes immutable enough to show the previous value, the user, and the timestamp?
Can supplier flowdown terms and controlled document sharing be tracked from purchase order to receipt?
Can the ERP trace a shipped serial number or lot back through materials, suppliers, operations, inspections, nonconformities, and revisions?
Can CUI be segmented, scoped, or restricted in a way that matches the company's CMMC boundary?
How fast can the system be implemented without weakening access control, traceability, or audit history?

The last question matters more than it looks like it might. Compliance pressure often arrives with a contract deadline. If implementing the ERP takes 18 months, the system may miss the commercial window that made the project urgent in the first place.

FAQ on ITAR and CMMC compliance software

What is ITAR compliance software?

ITAR compliance software helps companies manage operational controls related to the International Traffic in Arms Regulations, including controlled item classification, technical data access, export documentation, recordkeeping, audit trails, and supplier flowdown. For manufacturers, the ERP often needs to support these controls because controlled parts and technical data move through production, quality, purchasing, inventory, and shipping.

What is CMMC compliance software?

CMMC compliance software helps defense contractors manage cybersecurity requirements for protecting FCI and CUI. That may include security documentation, assessments, evidence, access control, audit logs, and control monitoring. An ERP is not a complete CMMC program, but if it stores or processes CUI, it needs to support the access, audit, and evidence requirements tied to the company's CMMC scope.

Does an ERP make a manufacturer ITAR compliant?

No ERP makes a manufacturer ITAR compliant by itself. ITAR compliance depends on classification, registration, licensing or approvals when required, export-control procedures, personnel controls, supplier management, training, and legal judgment. The ERP should support the operational side: controlled data labels, restricted access, traceability, record retention, change history, and evidence.

Does an ERP make a manufacturer CMMC compliant?

No ERP makes a manufacturer CMMC compliant by itself. CMMC covers the organization's cybersecurity practices across people, processes, systems, and networks. But an ERP can be in scope if it stores, processes, or transmits FCI or CUI. In that case, the ERP should support access control, identity management, audit history, data segmentation, and evidence collection.

What should aerospace and defense manufacturers look for in ERP?

Aerospace and defense manufacturers should look for ERP that supports controlled item classification, role-based access, document control, lot and serial traceability, supplier flowdown, quality records, immutable audit trails, and fast evidence retrieval. The system should help the team prove what happened without rebuilding the history from spreadsheets, folders, emails, and manual exports.
