EMEA | Tech Talk Tuesday: Securing OT Access

Operational technology environments were never designed for today’s access requirements. As organisations in manufacturing, energy, and critical infrastructure evolve, they must support a growing mix of internal users, third-party vendors, non-human identities, and emerging AI-driven processes, all interacting with sensitive OT systems. This creates a complex access challenge, shaped by legacy connectivity, fragmented network models, and a wide range of protocols across IT and OT.

In this session, we focused on how to securely manage and control access into OT environments without disrupting existing architecture or operational stability.

What we covered:

• How access is brokered across legacy and modern connectivity types without exposing critical systems
• How to securely manage third-party and vendor access into OT and industrial control environments
• How privileged access can be controlled without exposing credentials, even in constrained OT networks
• How to achieve full session visibility and auditability across IT and OT boundaries
• How identity risk extends beyond users to include service accounts, automation, and AI-driven agents interacting with OT systems

You’ll see how access into sensitive environments can be securely initiated, controlled, and monitored, regardless of network constraints or system limitations. Expect a practical, technically-led session with clear takeaways for securing access across complex OT estates.

Who should watch:

• Organisations operating OT environments: looking to control access across legacy systems, industrial networks, and critical infrastructure
• Teams managing vendor and third-party access: looking to reduce risk without impacting operational workflows
• Security and IT/OT convergence leaders: looking to secure both human and non-human identities across hybrid environment
