Zscaler for IoT and OT Security
Extend Zero Trust to Every Connected Device in Your Enterprise
As industrial and smart devices multiply across enterprise networks, traditional security approaches fall short. Zscaler for IoT and OT delivers zero trust security for the full spectrum of connected devices - from building management systems and IP cameras to industrial control systems and SCADA environments. TechPower helps organizations deploy and optimize this platform to eliminate blind spots, reduce attack surface, and meet compliance requirements without disrupting operations.

Overview
The explosion of IoT and operational technology (OT) devices has created a significant security challenge for IT teams. These devices are rarely designed with security in mind, cannot support traditional endpoint agents, and often run on legacy protocols that modern security tools struggle to inspect. At the same time, they connect to sensitive networks alongside business-critical systems.
Zscaler for IoT and OT addresses this gap with an agentless, cloud-native approach built on the Zscaler Zero Trust Exchange. It discovers, classifies, and enforces policy for every IoT and OT device on your network - without requiring hardware appliances, network redesign, or device-side agents.

Key Capabilities
Device Discovery and Classification
- Automatically discovers all connected IoT and OT devices across your environment
- Classifies devices by type, vendor, operating system, and risk profile
- Provides a continuously updated inventory to eliminate shadow IoT risks
- Identifies unmanaged and rogue devices that may bypass traditional controls
Zero Trust Policy Enforcement
- Applies least-privilege access policies to every device based on identity and context
- Prevents lateral movement by segmenting IoT and OT devices from enterprise systems
- Enforces granular, per-device policies without requiring network redesign
- Reduces reliance on VLANs and firewall rules that are difficult to scale
Inline Threat Prevention
- Inspects traffic to and from IoT and OT devices in real time
- Blocks known malware, command-and-control traffic, and exploits targeting connected devices
- Applies SSL/TLS inspection where appropriate without impacting device performance
- Integrates with Zscaler's global threat intelligence for up-to-date protection
OT-Specific Security Controls
- Designed to protect industrial environments where uptime and availability are critical
- Supports passive monitoring modes to avoid disrupting sensitive OT protocols
- Provides visibility into ICS and SCADA communications without inline interference
- Helps organizations align with frameworks such as IEC 62443 and NIST CSF
Centralized Visibility and Reporting
- Delivers a unified view of all IoT and OT device activity from a single cloud console
- Provides risk scoring and prioritized alerts to focus remediation efforts
- Supports audit-ready reporting for compliance and governance requirements
- Integrates with SIEM and SOAR platforms for streamlined security operations
