# NIST Broadens OT Cybersecurity Guidance

NIST released the initial public draft of Special Publication 800-82 Revision 4, expanding operational technology (OT) cybersecurity guidance for sectors including water, agriculture, transportation, buildings, and cloud-connected industrial systems. The draft emphasizes asset management, monitoring, governance, and OT expertise. It is guidance, not a new standalone legal requirement; contractors and operators may submit comments through November 30, 2026, **62 days from September 29**.

- Contractors and operators can review the draft’s focus areas and submit comments by November 30, 2026.
- The guidance may inform future demand for OT cybersecurity support, particularly asset management, monitoring, governance, and specialized OT expertise.
- Organizations can assess whether their OT cybersecurity offerings address these areas, while recognizing that the draft does not itself establish a mandatory compliance requirement.
