Defender for IoT
Agentless security and threat detection for OT, ICS, and IoT networks.
Microsoft Defender for IoT provides agentless network detection and response for operational technology (OT), industrial control systems (ICS), and IoT — discovering assets, identifying vulnerabilities, and detecting threats across environments where agents cannot be installed. It integrates with Microsoft Sentinel and Defender XDR for unified IT/OT security operations. Faltrox operates it as managed OT/IoT security.
Overview
What Defender for IoT is
OT, ICS, and IoT environments run critical processes but were never designed for security — they cannot take agents, run legacy protocols, and are increasingly targeted as IT and OT converge. Microsoft Defender for IoT secures them with an agentless, network-based approach that sees these devices without disrupting them.
It passively discovers and inventories OT/ICS/IoT assets, identifies their vulnerabilities, and detects threats and anomalies through deep protocol analysis of industrial and IoT traffic. It integrates with Microsoft Sentinel and Defender XDR so OT detections join IT security operations in one SOC, giving unified IT/OT visibility. Faltrox deploys the sensors, tunes the detection, and operates it as managed OT/IoT security.

Works with
Part of the platform
Microsoft products this pairs with, and the Faltrox services that operate it.
Delivery

Managed by Faltrox
Faltrox licenses, deploys, and tunes Microsoft Defender for IoT for your environment, then runs it as part of a managed service, so you get the protection without staffing another security console.
FAQ
Common questions
01Why can’t we just use endpoint security for OT and IoT?
Because OT, ICS, and IoT devices generally cannot take agents — they run legacy or embedded systems and critical processes that agents would disrupt. Defender for IoT uses an agentless, passive network approach to discover and secure these devices without touching them.
02How does it discover devices without agents?
Network sensors passively monitor traffic and use deep protocol analysis to discover and inventory OT/ICS/IoT assets, identify their vulnerabilities, and detect threats — all without installing anything on the devices or disrupting operations.
03Does it unify IT and OT security?
Yes — it integrates with Microsoft Sentinel and Defender XDR so OT detections join IT security operations in one SOC, giving unified visibility across the IT/OT boundary that is increasingly where attacks cross.
04Can it run in air-gapped OT environments?
Yes — it is deployable on-premises for air-gapped OT environments as well as cloud-connected, so it fits the data-residency and isolation constraints common in industrial settings.
05How does Faltrox operate it?
We deploy the network sensors, tune the detection, and run OT/IoT security operations — feeding detections into Microsoft Sentinel and the SOC we operate, delivering managed OT/IoT security alongside your IT defence.
