When IT Meets OT, Can Endpoint Security Hold The Line

Episode notes

How do you protect factory floors, utilities, and critical infrastructure when IT and OT finally run on the same nervous system? That is the challenge at the heart of my latest conversation with John Walsh, Field CTO at IGEL Technology, recorded live at the IGEL Now and Next event in Frankfurt. Back in March in Miami, John and I talked about zero trust as an ecosystem rather than a product, a way to bring unified management and strong policy enforcement to the endpoint. This time, we take that thinking to the operational technology world, where the stakes feel very different. When a cyberattack hits a factory, it is not only data at risk. It can stop production lines, damage equipment, and cost millions in downtime. John explains how a prevention first mindset, backed by IGEL’s immutable OS, Universal Management Suite, and OEM ready integrations, is helping manufacturers and OEMs move security out to the edge where attacks actually begin. Across the episode, John lifts the lid on IGEL’s work with partners such as Intel, Honeywell, Zscaler, and others who see OT as a growth frontier.
