Shared defense.
Shared standards.
Shared progress.
NS-ISAC is the peer network of plant cyber security, physical security, OT architects, and CISOs. We collaborate on cybersecurity, OT modernization, and operational resilience across the nuclear sector.
Who We Serve
Commercial operators, advanced reactor vendors, national laboratories, and federal regulators working together at the tactical level.
What We Do
Develop shared standards, templates, and conduct sector-wide training and exercises.
How We Collaborate
A trusted Community of Practice model. We focus on practitioner-to-practitioner knowledge sharing, bypassing the noise.
Featured Community Initiatives
Our working groups tackle the sector's most pressing OT and cybersecurity modernization challenges.
NEI 08-09 Rev 7 Transition
Shared adoption templates and tools to streamline implementation.
AI Governance
White paper and guidance development to ensure AI tools are securely implemented and utilized.
Assessments & Vulnerabilities
Peer-reviewed templates, benchmarking data, and implementation guidance.
Industry Collaboration
Cybersecurity at a nuclear facility is not an isolated problem. We bring together the entire ecosystem to raise the defensive floor.
Practitioner Perspectives
"The Vulnerability Tracking working group cut our implementation timeline in half. We weren't relearning lessons that other operators had already paid for."
Director, OT Cybersecurity
U.S. Commercial Operator
"Sharing our assessment methodology with peers, and getting theirs back, raised the floor across the sector. That's the whole point."
Principal Security Engineer
Advanced Reactor Vendor
"NS-ISAC is where the practitioners actually talk to each other, between the conferences and the standards meetings."
CISO
National Laboratory
Security-by-Design Focus Areas
Building resilience into the next generation of nuclear technology from day one.
