Top 10 Best Ot Asset Management Software of 2026

Dragos Platform pipelines OT network data into an asset registry that facilities teams can reconcile against existing CMDB and operational records. Discovery configuration supports narrowing scope to reduce irrelevant unmanaged switch discovery and reduce noise in large plants. Device and protocol attribution supports PLC, HMI, engineering station, and communications path context used for OT CMDB integration.

A key tradeoff is that richer attribution depends on consistent network visibility and correct discovery scope settings. It fits situations where network access allows passive network monitoring plus targeted active scanning during maintenance windows for firmware version tracking and engineering station mapping.

For OT asset inventory, Microsoft Defender for IoT focuses on mapping industrial devices seen on network traffic into a managed registry of assets, with protocol-aware identification rather than generic IP inventory. It supports configuration needed for air-gapped or segmented deployments by operating with collectors inside the OT network and forwarding data to the management service. The platform also adds operational controls like RBAC for administrative access and audit logging for security team governance.

A key tradeoff is that accurate ICS asset visibility depends on where sensors are placed and how much traffic is present, since passive network monitoring undercounts devices that never emit observable signals. It fits environments where engineering and security teams need continuous OT reconciliation and faster triage of unmanaged switch discovery patterns and PLC-facing communications.

Stellar is a fit for facilities and OT security teams that need asset inventory depth from mixed OT segments, including unmanaged switches and engineering station networks that do not advertise inventory cleanly. Discovery output is structured around OT device identity enrichment and ongoing reconciliation so asset records can reflect firmware and endpoint changes. Integration coverage is geared toward OT-specific workflows rather than generic IT CMDB-only import patterns.

One tradeoff is that discovery quality depends on network reachability and protocol visibility, especially when control networks restrict scanning paths or segment lateral routing. Stellar fits best when teams plan an iterative discovery rollout across OT zones, then tune governance rules to control which newly found endpoints become managed records. A common usage situation is onboarding a brownfield site where baseline identification is missing and multiple protocols must be recognized consistently before maintenance planning or security tagging can proceed.

Forescout eyeInspect targets OT asset inventory through continuous visibility, combining passive discovery with active validation to keep industrial endpoint and control-plane records current. The product focuses on enriching a cyber-physical asset registry with device attributes like firmware and role signals, then propagating those results into OT workflows for governance and reconciliation.

Admin control centers on classification and policy alignment for identified assets, including auditability for what was observed and what actions were applied. Automation support is built around discovery-driven enrichment and integrations into downstream systems used for OT CMDB and operations.

Verve by Rockwell Automation maintains an OT asset inventory by pulling device and network signals into a managed registry for facilities and control-system teams. It emphasizes Rockwell-centric operational visibility, including device identity enrichment for endpoints and assets connected to Rockwell environments.

Verve also supports integration-oriented workflows such as synchronization with external systems for downstream CMDB use and operational reporting. Administrators can control access and audit operational changes to the registry as teams expand scanning and reconciliation coverage.

Asimily is an OT asset management system built for facilities and OT teams that need visibility into industrial networks and control-layer endpoints. It focuses on turning observed device data into an asset inventory that can be maintained with ongoing checks rather than one-time imports.

The core value is integration depth through external system hooks like OT CMDB workflows and IT/OT data exchange patterns, plus automation for reconciling inventory changes as the network evolves. Asimily is most distinct when asset attribution and relationship mapping must stay consistent across multi-site environments with mixed device types.

Radiflow iSID is built for OT asset discovery workflows that blend passive network monitoring with active interrogation results. It maps discovered devices into an OT-focused inventory workflow that supports reconciliation against existing asset records and engineering naming conventions.

The product emphasizes automation through integration hooks, including APIs for pulling inventory and feeding downstream systems like OT CMDBs. It also targets governance needs with administrative controls for discovery scope and operational change tracking across repeated scans.

Cisco Cyber Vision is an OT asset management solution that maps industrial networks into an ICS asset inventory by combining passive collection with active inspection when needed. It performs protocol-aware device recognition to derive asset identity signals such as device type and firmware-related details.

The system supports OT discovery workflows across multiple network segments and can reconcile discovered assets into an asset registry that teams can use for governance and remediation tracking. Operational integration is driven through defined export paths and automation hooks that support downstream inventory and control processes.

PAS Cyber Integrity from hexagon.com performs OT asset inventory by combining network visibility with OT-specific identification and enrichment. It focuses on building an auditable cyber-physical asset registry that supports reconciliation workflows against existing inventories.

The solution supports automation through configurable discovery rules and integration hooks for downstream OT CMDB and governance processes. It also tracks key asset attributes such as device identity and firmware-related properties needed for cyber reporting.

Industrial Defender Security Management System targets OT asset inventory and cyber asset registration with security workflows tied to industrial environments. It supports passive and active network visibility to surface unmanaged network endpoints, then maps them into an OT-focused registry for downstream controls.

The product also integrates vendor context and engineering identifiers to improve reconciliation between what exists on the network and what systems expect in operations. Coverage is strongest when governance needs include repeatable scanning cycles and auditable changes to device records rather than ad hoc spreadsheets.
