Expanded offerings combine OT SDN visibility, ruggedized security monitoring, lifecycle cybersecurity services and compliance expertise to help operators strengthen resilience and regulatory readiness.

SAN FRANCISCO and PULLMAN, Wash. , Oct. 20, 2026 /PRNewswire/ — Nozomi Networks, the leader in OT, IoT and CPS security, and Schweitzer Engineering Laboratories (SEL), industry-leading innovators in the power system protection, automation, and infrastructure solution space, today announced an expansion of their global partnership to help critical infrastructure operators strengthen cyber resilience, improve operational visibility and address evolving regulatory requirements.

Combining Trusted Technology, Services and Industry Expertise
Building on a successful collaboration serving utilities and other critical infrastructure organizations worldwide, the expanded partnership combines Nozomi Networks’ AI-powered cybersecurity platform with SEL industrial networking software, OT managed ethernet switches, trusted computing platforms, cybersecurity services and regulatory expertise. Together, the companies provide customers with a more comprehensive portfolio of technologies and services designed to accelerate and scale security programs while supporting compliance with frameworks, such as NERC CIP, IEC 62443 and NIST guidance, including the expanding Internal Network Security Monitoring (INSM) requirements under NERC CIP-015-1.

Expanding Visibility and Deployment Flexibility
The expanded partnership introduces a direct integration between the Nozomi platform and SEL OT Software-Defined Networking (OT SDN). In addition to offering the strongest option for deny-by-default architecture, OT SDN provides authoritative network intelligence from the control layer, including near real-time visibility of connected assets, traffic flows, network policies and physical topology. By incorporating this intelligence directly into the Nozomi Networks platform, organizations gain deeper visibility into managed environments while enhancing threat detection, anomaly detection, asset intelligence and AI-powered risk analysis, capabilities that can help utilities address growing INSM requirements of NERC CIP-015-1.

Nozomi Networks Guardian security sensors can now be installed directly on SEL-3355 Computing Platforms. This offering enables customers to deploy advanced OT and critical infrastructure monitoring on ruggedized hardware designed for demanding environments, while giving organizations that already know and trust SEL hardware another option for standardizing cybersecurity monitoring across their operations.

Nozomi and SEL are committed to continued innovation on industry-leading industrial platforms. The Nozomi Networks platform and SEL Blueframe can provide organizations with robust data collection and deployment options for enterprise security management that use existing infrastructure investments to strengthen resilience and streamline compliance through integrated architecture options.

A More Comprehensive Approach to Cyber Resilience
“Critical infrastructure operators must strengthen cybersecurity without compromising the reliability and availability of essential operations,” said Ryan Bradetich, Schweitzer Engineering Laboratories Senior Vice President of Communications and Cybersecurity. “This expanded partnership gives customers greater flexibility in how they deploy, monitor and protect their environments, helping them meet evolving security and regulatory requirements while maintaining operational performance.”

“For more than four decades, SEL has helped protect critical infrastructure and make electric power safer and more reliable,” said Matthew Cowell, Nozomi Networks Vice President of Strategic Alliances. “Our shared commitment to safety, reliability and operational uptime makes this a natural collaboration. Together, we are combining trusted industrial technology with AI-powered cybersecurity to help customers reduce risk and build more resilient operations worldwide.”

The OT SDN integration and SEL-3355 Computing Platform with the Nozomi Networks Guardian operating system installed directly on the appliance are available today.
