Key Features
- Enhanced Access Control for OT: Implements data filters, deny-unless rules, and query rules to strengthen security controls on OT data.
- OT Network Map: Available in the Industrial Workspace, it visualizes sites, subnets, and OT devices, including device-to-device connections with detailed port and protocol information.
- CMDB OT Class Model Updates: Adds the IP Network Subnets related list across multiple CMDB classes to display subnet associations and includes OT device details directly in form views for key classes, streamlining device management.
- About Industrial Workspace Page: Displays installed OT applications and versions within the ServiceNow AI Platform for easy tracking and updates.
- Pre-import OT Worksheet Entry Review (POWER) Tool Enhancements: Supports importing OT device data via Excel spreadsheets with improved validations and the ability to create remediation tasks for invalid records.
- User Interface Improvements: Includes new related lists (e.g., VLANs, software, firmware), renamed modules for clarity, and the addition of an “Is Virtual” field to identify virtual OT devices.
- Automated IT OT Bulk Contextualization: Renamed from Automated IT OT Bulk Conversion, with processing limits and updated role dependencies to enhance large-scale contextualization of IT and OT CIs.
- New Coral Theme: Introduces a fresh, brand-neutral interface with an optional dark mode to improve user experience across portals and mobile devices.
Administrative and Role Management Updates
- Granular admin roles are introduced to allow configuration tasks without full admin privileges.
- Operational Technology Manager roles now restrict editing to OT CIs only, preventing unauthorized changes to IT CIs.
- Some UI elements like the "New" button were removed for users with read-only site access to improve security.
Activation and Additional Information
Operational Technology Manager must be installed via the ServiceNow Store. It automatically installs the latest OT extension classes from the CMDB CI Class Models application. The release also includes support for the Service Graph Connector for Microsoft Excel to streamline OT data imports and remediation.
Why This Matters
These enhancements empower ServiceNow customers to better secure, visualize, and manage their OT environments by integrating OT asset data with IT infrastructure, improving operational insight and control. The improved CMDB integration and network mapping facilitate more accurate device tracking and relationships, which are critical for industrial operations management and risk mitigation.
The ServiceNow® Operational Technology Manager application enables you to aggregate Operational Technology device data from multiple sources so you can build foundational data relationships in the Industrial solution. Operational Technology Manager was enhanced and updated in the Zurich release.
