The National Institute of Standards and Technology (NIST) Special Publication 800-171 provides the essential framework to ensure your organization meets strict security requirements — and stays competitive in a demanding market.
What is NIST 800-171?
The NIST 800-171 (National Institute of Standards and Technology Special Publication 800-171) is a critical framework designed to protect Controlled Unclassified Information (CUI) in non-federal systems and organizations. Originally published to safeguard sensitive data shared with contractors, suppliers, and partners, this standard helps ensure the confidentiality, integrity, and availability of CUI outside federal environments.
What is the scope of NIST 800-171?
NIST 800-171 was created to protect Controlled Unclassified Information (CUI) when it resides in non-federal information systems.
This compliance framework applies to any organization that stores, processes, or transmits CUI on behalf of a U.S. federal agency — especially within the defense, manufacturing, technology, and service sectors.
It’s not limited to defense contractors. Many private businesses handling sensitive information in contracts, research projects, or collaborations with government agencies must also comply.
In simple terms:
If your business has access to government data labeled as CUI, you are responsible for implementing security controls outlined in NIST 800-171.

Benefits of being NIST 800-171 compliant
Achieving compliance with NIST 800-171 is more than just checking a box — it delivers tangible advantages that strengthen your organization’s security posture and business growth potential.
Win more federal contracts
Many U.S. government agencies and prime contractors now require NIST 800-171 compliance as a prerequisite for doing business. Being compliant opens doors to lucrative federal opportunities, particularly in the defense, aerospace, and technology sectors.
