For manufacturers involved in the Defense Industrial Base (DIB), non-compliance with DFARS (Defense Federal Acquisition Regulation Supplement) and its underlying requirement for NIST SP 800-171 is not merely a bureaucratic oversight; it carries severe and far-reaching consequences that can jeopardize your entire business.

The repercussions include:

• Loss of Government Contracts: This is arguably the most immediate and devastating impact. The DoD can terminate existing contracts, and you will be ineligible for new ones if you cannot demonstrate compliance. This directly impacts your revenue and long-term business viability in the defense sector.

• Inability to Bid on New Opportunities: Non-compliant organizations will be unable to compete for new DoD contracts, cutting off a significant market segment.

• Supply Chain Disruption: Prime contractors are increasingly holding their subcontractors accountable for compliance. Your non-compliance could make you an undesirable partner, leading to a loss of business from larger entities.

• Reputational Damage: News of non-compliance, especially if it leads to a data breach of Controlled Unclassified Information (CUI), can severely tarnish your company’s reputation, affecting relationships with all clients, not just government ones.

• Legal and Financial Penalties: While direct fines for NIST SP 800-171 non-compliance are still evolving, providing false certifications to the government can lead to False Claims Act violations, resulting in substantial financial penalties and potential legal action.

• Increased Cyber Risk: Most importantly, non-compliance means you are leaving critical vulnerabilities unaddressed. This significantly increases your risk of a costly cyberattack, data breach, and operational disruption.

• Exclusion from DoD Supply Chain: Ultimately, consistent non-compliance or a significant security incident due to negligence could lead to permanent exclusion from the defense supply chain.

In summary, for manufacturers handling CUI, NIST 800-171 compliance is not optional; it’s a fundamental requirement for operating in and contributing to national security. The consequences of neglecting it are too high to ignore.
