Zero lateral movement. Zero attack surface.
Agentless zero trust segmentation eliminates the risk of lateral movement inside your factory by isolating production lines and individual endpoints without adding software.
Easily segment IT from OT and IoT
Eliminate east-west firewalls and NAC
Deploy in hours with no downtime, agents, or VLAN readdressing
The Problem
Legacy architectures, legacy risks
Manual VLAN segmentation, NAC, and ACL projects never finish.
Legacy infrastructure mixed with modern systems
Decades-old OT devices can’t be patched or upgraded, leaving critical vulnerabilities.
More third-party access
Partners, vendors, and outsourced support demand secure, seamless communications.
Flat, complex networks
Traditional architectures make it easy for threats to spread once inside.
Solution Overview
Zscaler OT/IoT Segmentation is an agentless solution that replaces firewalls, NAC, and manual VLANs. Fully isolate your devices without agents, upgrades, or downtime. Keep legacy machines and headless systems safe and operational. With automated policies, you get security that’s simple and works seamlessly, without slowing down production.
Solution Details
Improve uptime and simplify operations
Eliminate manual configuration errors. Empower local OT teams to handle routine problems, easing trouble ticket pressure on your IT team.
Automated Provisioning
Isolate every device into a segment of one (using /32).
Automated Policy Grouping
Group devices, users, and apps for policy enforcement automatically.
Policy Enforcement
Enforce dynamic policy for east-west traffic and IT/OT and Purdue layer separation.
Agentless Deployment
Eliminate east-west firewalls, NAC appliances, and agent-based software.
Ransomware Kill Switch
Automate incident response with simple, user-selectable attack surface reduction. Just choose a pre-set severity level to progressively lock down known vulnerable protocols and ports.
Pre-Set Policies
Align protection to real-time risk with four selectable policy levels based on severity.
Controlled Access
Restrict critical infrastructure access to known MAC addresses only.
SIEM/SOAR Integration
Integrate seamlessly with your existing SIEM and SOAR for automated response.
Port and Protocol Blocking
Instantly block the protocols most favored by ransomware, like RDP/SMB and SSH.
Start by discovering every OT device
Discover and classify all device assets in real time, with full east-west visibility and control. Take back control with no endpoint agents to deploy or manage.
Device Discovery and Classification
Automatically discover and classify devices in east-west LAN traffic.
Traffic Analysis
Baseline your traffic patterns and device behaviors as well as identify authorized and unauthorized access.
Network Insights
Gain accurate network insights to support performance management and threat mapping.
Real-Time Automapping
Leverage third-party integrations for querying, tagging, and alert monitoring.
