NIST SP 800-171 is a set of security guidelines created by the National Institute of Standards and Technology (NIST). These standards are designed to protect Controlled Unclassified Information (CUI) when handled by non-federal systems, particularly by government contractors and subcontractors.
If your small business works with the U.S. government — especially the Department of Defense (DoD) — you’re required to follow NIST SP 800-171 to keep sensitive data secure and stay eligible for future contracts.
Why Compliance Matters for Small Businesses
Many small businesses think compliance is just for big defense contractors. But the reality is:
👉 If your company touches CUI, you must comply.
Failure to do so can lead to lost contracts, penalties, or even removal from the federal vendor pool.
The good news? You don’t need a massive IT team to get started. This guide breaks it down into quick, practical steps tailored for small businesses.
