NIST 800-171: Origin and Importance

Origin

NIST Special Publication 800-171 was created by the National Institute of Standards and Technology (NIST), a non-regulatory agency within the U.S. Department of Commerce. First published in June 2015 and subsequently revised, it was developed in response to Executive Order 13556, which aimed to establish standards for protecting Controlled Unclassified Information (CUI). The framework was specifically designed to help non-federal organizations that handle, store, or process CUI on behalf of the federal government implement appropriate security controls to protect sensitive government information outside of federal systems.

Industry Importance

NIST 800-171 has become critically important in the defense industrial base and federal contracting sectors, as compliance is now mandatory for organizations working with the Department of Defense and other federal agencies that handle CUI. The certification demonstrates that an organization has implemented 110 security requirements across 14 control families, covering areas such as access control, incident response, and system integrity. Beyond contractual requirements, achieving NIST 800-171 compliance has become a competitive differentiator and trust signal in the marketplace, showing clients and partners that an organization takes cybersecurity seriously and follows recognized best practices for protecting sensitive information.
