Yokogawa presents a managed IT/OT security operations center with continuous monitoring, incident tickets, workflows, and service levels. Buyers need a site-specific handoff matrix showing who owns triage, when the plant team takes control, how operating state changes escalation, and which evidence closes the service-customer loop.
TXOne's registered products URL currently resolves to a deployment-architecture page that identifies Stellar as endpoint protection for OT and ICS environments. Endpoint security can support a defense layer, but only authorized operations, control engineering, and safety processes can establish whether the physical process is in a defined safe state.
Dragos documents OT asset visibility, vulnerability management, threat detection, and response capabilities. An observed inventory and communication map can inform architecture review, but it cannot decide the approved security zones, conduits, trust boundaries, safety constraints, or change plan for a live industrial system.
Claroty documents a platform that uses cyber-physical-system visibility to define and recommend network policies that teams can monitor, refine, and enforce through existing firewalls, switches, or network-access controls. The recommendation is security analysis; production change authority remains a separate operational decision.
Microsoft documents Defender for IoT for cyber-physical asset discovery, vulnerability management, and threat detection. An alert can support investigation, but isolating an operational asset still requires verified process context and the site's engineering, safety, operations, and change authority.
Dispel documents zero-trust remote access, vendor session control, identity controls, isolation, and audit records for industrial environments. Those controls can govern how a person reaches an OT asset, but they do not approve the maintenance task, establish a safe plant state, or transfer engineering and operating authority.
Tenable documents asset inventory, exposure prioritization, configuration-change detection, network monitoring, and remediation guidance for cyber-physical systems. In an operating environment, the finding still has to pass asset-owner, engineering, safety, production, vendor, change-control, and recovery review before anyone changes the device or network.
