Most factory security incidents don't start big; they start with a compromised contractor portal, a vulnerable edge device or a flat network that lets attackers move freely once they're in. Three-quarters of manufacturing cyberattacks target edge devices, and without effective segmentation, small issues escalate quickly into factorywide shutdowns.

This session presents Zscaler's annual IoT and OT threat data with a focus on manufacturing, and examines practical architectural approaches that reduce lateral movement while keeping production online.

In this insightful discussion, Zscaler's Umang Barman and Sven Becher discuss:

• How attackers exploit edge devices and flat networks to move laterally across OT environments;
• Why traditional VLAN-based segmentation falls short, and what agentless microsegmentation achieves;
• How zero trust architecture enables secure OT-to-cloud connectivity without exposing factory systems.
