List of the Top 4 Operational Technology (OT) Security Software for Aruba ClearPass in 2026

Ongoing asset identification, vulnerability assessment, threat monitoring, and continuous discovery are essential for your Internet of Things (IoT) and operational technology (OT) devices. To foster innovation within IoT and OT, it is crucial to implement robust security measures across all devices in these categories. Microsoft Defender for IoT offers a solution that operates at the network level without requiring agents, allowing organizations to deploy it swiftly. This tool is compatible with a wide range of industrial machinery and can seamlessly integrate with Microsoft Sentinel and other security operations center (SOC) tools. It supports deployment in both on-premises settings and Azure-connected environments. The lightweight nature of Microsoft Defender for IoT enables it to provide device-layer security, which is particularly beneficial for new IoT and OT projects. Utilizing passive, agentless network monitoring, this solution generates a thorough inventory and detailed analysis of all IoT and OT assets without disrupting network operations. Furthermore, it can analyze various industrial protocols to extract crucial device information, such as the manufacturer, device type, firmware version, and IP or MAC address, thereby enhancing overall security visibility and management. This comprehensive approach not only safeguards devices but also strengthens organizational resilience against potential threats.
