    OT Device Management

    To fully manage OT devices, ServiceNow customers need the following core applications and features:

    • Operational Technology Manager (snotfoundation): Establishes foundational data and relationships critical for the OT Management solution.
    • IT Discovery for OT Networks (snotsmdiscovery): Discovers IT-class OT devices within Industrial Control System (ICS) networks, including switches, routers, and computers across data centers and factories.
    • OT Enhanced Access Control (snotenhancedacl): Enhances system security by applying data filters and access control rules tailored for OT environments.
    • OT Manager Foundation (snotmgenai): Leverages generative AI to streamline OT device data processes within the Industrial Workspace.
    • OT Asset Management (com.snotam): Provides lifecycle management for OT and Operational Equipment (OE) assets as part of Enterprise Asset Management.
    • Operational Technology Change Management (snotchgmgmt): Facilitates collaborative management of changes to OT devices and industrial equipment configurations.
    • Recommended Actions for OTSM (snotsmra): Enables real-time actionable recommendations to accelerate issue triage and resolution in OT incidents and records.
    • ServiceNow Otto for OT Service Management (snotsmgenai): Assists teams in summarizing OT incident details and generating resolution notes to improve communication.

    Note: OT licenses apply specifically to Operational Technology Service Management (OTSM), not to IT Service Management (ITSM).

    OT Vulnerability Management

    For comprehensive OT vulnerability tracking and remediation, these applications and features are required:

    • Operational Technology Vulnerability Response (snotvr): Prioritizes and manages remediation of OT device vulnerabilities based on criticality within the production process.
    • Hardware Vulnerability Assessment (snotvrpro): Assesses firmware vulnerabilities of OT devices and generates Vulnerable Items (VIT) linked to impacted devices.
    • Vulnerability Solution Management (snvulsolution): Automates correlation of vulnerabilities with remediation solutions such as patches and configuration updates, reducing manual effort.
    • Operational Technology Manager (snotfoundation): Provides foundational data and relationships needed for OT vulnerability management.
    • OT Enhanced Access Control (snotenhancedacl): Applies security controls to protect OT vulnerability data.
    • OT Manager Foundation (snotmgenai): Uses generative AI to optimize processes related to OT device and vulnerability data.

    The following tables describe the application dependencies required for Operational Technology (OT) device management and OT vulnerability management.

    OT device management

    For a full view of your OT device data and its management, you need the applications and features in the following table.

    Note:
    OT licenses for Operational Technology Service Management (OTSM) apply to OTSM, not ITSM.
    Application/Feature Description
    Operational Technology Manager (sn_ot_foundation) Creates the foundational data and relationships that enable your enterprise to use the Operational Technology Management solution.

    For more information, see Operational Technology Manager.
    IT Discovery for OT Networks (sn_otsm_discovery) Discovers IT class OT devices. These devices are located in designated Purdue levels within your Industrial Control System (ICS) networks. IT class items include switches, routers, and computers that exist both in data centers and in your factories.

    For more information, see IT Discovery for Operational Technology (OT) Networks.
    OT Enhanced Access Control (sn_ot_enhanced_acl) Implements data filters, deny unless access control rules (ACLs), and ACL query rules to help improve system security.

    For more information, see Enhanced Access Control for Operational Technology.
    OT Manager Foundation (sn_otm_gen_ai) Uses generative AI to help streamline processes in the Industrial Workspace related to your OT device data.

    For more information, see Operational Technology (OT) Manager Foundation.
    OT Asset Management (com.sn_otam) A specialized offering within the suite of Enterprise Asset Management solutions for managing OT and Operational Equipment (OE) assets. With OT Asset Management, you can effectively manage the lifecycle of OT and OE assets.

    For more information, see OT Asset Management.
    Operational Technology Change Management (sn_ot_chg_mgmt) Enables your team members to work collaboratively on changes to OT devices or industrial equipment configurations.

    For more information, see Operational Technology Change Management.
    Recommended Actions for Operational Technology Service Management (OTSM) (sn_otsm_ra) Enables you to set up and apply real-time actionable recommendations for speeding up the triaging process and resolving issues quickly across various records in the Industrial Workspace, including OT incidents.

    For more information, see Recommended Actions for Operational Technology Service Management (OTSM).
    ServiceNow Otto for Operational Technology (OT) Service Management (sn_otsm_gen_ai) Enables teams to summarize OT incident details and generate incident resolution notes to share with other users.

    For more information, see ServiceNow Otto for Operational Technology (OT) Service Management.

    OT vulnerability management

    For a full view of your OT vulnerability data and its tracking, you need the applications and features in the following table.

    Application/Feature Description
    Operational Technology Vulnerability Response (sn_otvr) Enables effective prioritization and remediation of OT device vulnerabilities at the site level. By using the CMDB relationships of OT devices, vulnerable devices or items can be prioritized based on the criticality of the production process they automate.

    For more information, see Operational Technology Vulnerability Response.
    Hardware Vulnerability Assessment (sn_otvr_pro) Enables you to assess the firmware vulnerabilities of the OT devices in inventory and create vulnerable items (VIT) against the impacted OT devices.

    For more information, see Operational Technology Hardware Vulnerability Assessment.
    Vulnerability Solution Management (sn_vul_solution) Automates the correlation of vulnerabilities in your environment with the solutions that can remediate them. It identifies the patches, configuration updates, and controls with the highest impact for your organization, eliminating the need for manual research.

    For more information, see Vulnerability Solution Management.
    Operational Technology Manager (sn_ot_foundation) Creates the foundational data and relationships that enable your enterprise to use the Operational Technology Management solution.

    For more information, see Operational Technology Manager.
    OT Enhanced Access Control (sn_ot_enhanced_acl) Implements data filters, deny unless access control rules (ACLs), and ACL query rules to help improve system security.

    For more information, see Enhanced Access Control for Operational Technology.
