S&I – NIST 800-171
Protecting Controlled Unclassified Information (CUI)
Safeguard Controlled Unclassified Information with confidence through NIST 800-171 compliance. S&I Security provides expert guidance and customized solutions to help your organisation meet stringent federal requirements, protect sensitive government data, and build lasting trust with stakeholders.
What is NIST 800-171?
NIST 800-171, developed by the National Institute of Standards and Technology, provides a comprehensive set of guidelines for securing Controlled Unclassified Information (CUI) within non-federal systems. The framework includes 110 security requirements across 14 control families, such as access control, incident response, and system integrity, designed to safeguard the confidentiality of sensitive government data. Compliance is mandatory for organisations handling CUI under federal contracts, particularly those governed by the Defense Federal Acquisition Regulation Supplement (DFARS). Implementing NIST 800-171 not only ensures regulatory compliance but also strengthens your cybersecurity posture and demonstrates a commitment to data protection.
