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 users with a 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.
The expanded partnership introduces a direct integration between the Nozomi platform and SEL OT Software-Defined Networking (OT SDN).
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.
More Visibility
By incorporating this 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 install directly on SEL-3355 Computing Platforms. This offering enables users 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.
“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.”
