In this special RSA Conference edition of Cyber Focus, host Frank Cilluffo sits down with Edgard Capdevielle, President and CEO of Nozomi Networks, to unpack the evolving landscape of operational technology (OT) cybersecurity. Together, they explore how digital transformation and the convergence of IT and OT are reshaping the threat environment for critical infrastructure. Capdevielle outlines the three major phases of the OT security market, reflects on the role of AI and legacy systems, and explains why visibility remains foundational to cybersecurity. The conversation also highlights the growing risk from nation-state actors, the breakdown of air gap assumptions, and the tangible steps owner-operators must take to build resilience.

Main Topics Covered:

• Defining the three phases of OT cybersecurity market maturity
• The impact of digital transformation and IT/OT convergence
• Why visibility remains the top concern for infrastructure operators
• The role of AI in passive detection and firmware profiling
• Nation-state threats, air gap fallacies, and Volt Typhoon’s implications
• Practical steps for operators to improve risk visibility and resilience
