Restraint - Data Security Barriers to Hamper Defense Work Outsourcing

Defense agencies are reluctant to outsource engineering tasks when sensitive intellectual property is at stake. The core problem is regulatory overlap. The International Traffic in Arms Regulations (ITAR) rules explicitly prohibit foreign support personnel from accessing in-scope data. Outsourcing IT to foreign nations risks ITAR violations if it allows system administrator access to protected technical information. Compliance requirements have also become strict.

The CMMC 2.0 final rule became effective in December 2024, and CMMC requirements began appearing in DoD contracts starting in November 2025. It raised the certification bar for any third-party engineering partner. In December 2025, the DOJ settled with Swiss Automation Inc., an Illinois-based machining firm, for inadequately protecting technical drawings for DoD parts. This shows that enforcement is now reaching subcontractors and small-scale suppliers. Until vendors can reliably demonstrate the protection of classified data, defense outsourcing will likely remain limited.
