Breached OT Kills. Zero Trust 2.0 Doesn’t
Not long ago, OT environments were isolated islands.
Control systems ran independently, accessible only through dedicated workstations requiring physical presence. The factory floor and the IT department might as well have been on different planets.
That world is gone.
Today’s OT environments are connected. Remote access from IT workspaces to control systems is routine.
And this is just the start.
And it changes everything about how to secure them.
In this episode of Threat Talks, Lieuwe Jan Koning and Rob Maas break down what happens when OT vs IT security models collide – and why IT/OT convergence is forcing organizations to rethink how they protect industrial environments.
Patching is difficult, availability is critical, and legacy models like the Purdue model leave gaps attackers can move through.
So, what does work?
Zero Trust.
If your organization relies on industrial systems, this is the shift you need to understand.
