As OT environments become more connected and contractor access expands the attack surface, traditional perimeter defenses are no longer enough. Hitesh Chhabra of Zscaler examines why VPN-based access and firewall-centric architectures leave manufacturing environments exposed and how zero trust principles can address the security gaps that legacy models leave behind.

In this session, he will share insights on:

• Why vendor and contractor remote access represents one of the biggest attack vectors in OT environments;
• How zero trust segmentation - agentless east-west and north-south - enables manufacturers to achieve micro and macro segmentation without downtime or infrastructure changes;
• How OT deception technology, cellular endpoint security and outbound connectivity controls combine to create a proactive, layered security posture for factory environments.
