The complex nature of governance in modern industrial environments leaves a critical question unanswered: who is ultimately responsible for OT security - IT, OT, the C-suite, or all three? As digitization accelerates and IT-OT convergence rewrites accountability structures, the answer demands more than a reporting line.

In this insightful discussion, Mantas Mazeikis, Tony Jarvis, Jacxine Fernandez and Shilpy Banerjee discuss:

• How IT-OT convergence is reshaping security roles, and why federated accountability with defined outcomes is more effective than assigning a single owner;
• What a robust governance framework looks like in practice, including technical operating standards, cross-functional committees, shared risk language and RACI-level role clarity that eliminates the waiting game between teams;
• How to manage cross-departmental collaboration and communication, and why embedding security into procurement contracts, change management and vendor access reviews is the next frontier in OT security ownership.
