What You’ll Learn in This Executive Briefing
For industrial and critical infrastructure organizations, operational technology environments have moved from isolated networks to deeply interconnected systems that run the business. Connectivity brings efficiency, but it also brings real exposure: unknown assets, legacy devices, flat networks, and a widening gap between IT security operations and OT reality. The cost of getting this wrong shows up as operational downtime, safety incidents, regulatory exposure, and direct revenue impact.
Join Hitachi Cyber and Nozomi Networks for a practical executive session on how leading organizations move from discovery to defense to resilience. See how continuous OT/IoT asset visibility and threat detection from Nozomi combines with 24/7 managed detection, response, and advisory services from Hitachi Cyber to deliver a complete, operator-grade security program for industrial environments.
This session will help you go:
- From fragmented visibility to unified operational control
- From reactive response to proactive resilience
- From technical noise to board-level clarity
Join us to learn:
- How to gain control over unknown OT risk and build a continuously updated inventory of your OT, IoT, and ICS assets without disrupting operations
- How to operationalize 24/7 threat detection and incident response purpose-built for OT, even with limited in-house resources
- How to translate technical OT risk into board-level governance, compliance, and investment decisions — and what a joint Nozomi Networks and Hitachi Cyber engagement looks like in practice
Who should attend:
This session is designed for senior security and operations leaders in industrial and critical infrastructure organizations, including CISOs, CIOs, COOs, VPs of Security, Heads of OT, SOC Directors, and Plant or Site Managers.
