Hitachi Cyber and Nozomi Networks join forces to deliver world-class OT and IoT monitoring solutions

Santa Clara, December 04, 2025 - Hitachi Systems Trusted Cyber Management Inc., which provides global cybersecurity services under the brand name “Hitachi Cyber,” today announced a strategic collaboration with Nozomi Networks, the leader in OT, IoT and CPS security. Together, the two organizations will deliver world-class OT and IoT monitoring and visibility solutions designed to secure industrial systems across energy, mobility, and manufacturing sectors worldwide.
 

A Powerful Alliance for Industrial Cyber Resilience

This collaboration combines Hitachi’s century-long industrial heritage with Nozomi Networks’ cutting-edge OT, IoT and CPS visibility and security technology. As the global cybersecurity arm of Hitachi Systems, Hitachi Cyber unites the group’s extensive experience in energy, rail, and industrial manufacturing with its growing leadership in AI-driven digital transformation and managed security services.
 

Now available as part of Hitachi Cyber’s managed security services offering, Nozomi Networks’ platform provides real-time visibility, advanced anomaly detection, and AI-based threat intelligence—key capabilities that, when integrated with Hitachi Cyber’s cybersecurity expertise and industry reach, create a comprehensive, scalable defense framework for critical operations.
 

“Hitachi has been protecting industrial systems for more than a century,” said Hiroaki Koiwa, CEO of Hitachi Systems Trusted Cyber Management Inc. “By partnering with Nozomi Networks, we’re taking that mission further—safeguarding the very infrastructure societies rely on and ensuring operational continuity across industries that power modern life.”

The OT Threat Landscape: A Growing Concerns for Boards and Nations

The operational technology and critical infrastructure sectors have become prime targets for cyber threat actors. The operational technology and critical infrastructure sectors are facing unprecedented pressure as cyber threat actors increasingly shift their focus toward industrial environments. Around the world, organizations are reporting a steady rise in OT-related cyber incidents and a significant increase in attacks aimed at essential services. These threats go far beyond financial impact—they carry real safety and societal consequences, from energy disruptions and transportation delays to widespread supply-chain impacts.
 

These incidents are not just financial risks—they pose serious safety and societal consequences, from energy outages and transportation disruptions to supply chain breakdowns.
 

“The convergence of IT and OT and the extensive use of IoT devices has created unprecedented exposure for industrial and critical infrastructure organizations”, said Edgard Capdevielle, President and CEO of Nozomi Networks. “Our partnership with Hitachi Cyber extends the reach of our AI-powered OT and IoT security innovation, empowering organizations to see and respond to threats faster—protecting people, assets, and societies.”

Cybersecurity: From IT Issue to Board-Level Responsibility

As organizations undergo digital transformation, they are increasingly integrating IT and OT systems, relying on complex supply chains and third-party ecosystems. This evolution makes cybersecurity not merely a technical concern, but a board-level matter—central to business continuity, compliance, and public safety.
 

Through this partnership, Hitachi Cyber and Nozomi Networks are helping enterprises build secure, resilient, and intelligent operational environments that protect citizens and sustain critical services.

From Innovation to Impact: Co-Creation and Beta Engagements

The collaboration will begin with joint proofs of concept (PoCs) within the Hitachi Group’s own industrial ecosystem to refine the joint solution in real-world environments.
 

Following internal validation, Hitachi Cyber will enter a beta phase with select customers, co-developing customized OT and IoT monitoring solutions designed to solve specific operational challenges through a concerted, multi-disciplinary effort that merges engineering, operations, and cybersecurity expertise.

What’s Next

This partnership marks the next evolution in Hitachi Cyber’s global mission: protecting the interconnected world by merging Hitachi’s trusted industrial legacy with Nozomi Networks’ AI-powered OT and IoT intelligence.
 

Together, Hitachi Cyber and Nozomi Networks are securing not only critical systems—but the societies that depend on them.
 

What’s next: A safer, more connected world.
