Curated Supplier · OT / IoT · Agentless Discovery

Armis — agentless visibility across every device you can't put an agent on.

Armis discovers and secures managed, unmanaged, IoT, OT, and medical devices without agents — its strength is breadth, seeing the whole connected estate including the things traditional endpoint tools miss. For healthcare, retail, and enterprise teams whose real problem is "we don't even know what's on the network," Armis's discovery reach is the lead story.

What Armis actually does.

Armis builds a real-time inventory of every connected device — managed endpoints, unmanaged IoT, OT, and medical devices — using passive, agentless collection and a large device knowledge base for identification and risk context. The differentiator is breadth: instead of going deep on one device class, Armis aims to see everything connected across IT, IoT, OT, and IoMT in a single platform. For organizations whose biggest gap is visibility, that span is the value.

Capabilities · A short list

Who this fits.

Best Fit

Healthcare, retail, or enterprise needing broad device visibility

If the core problem is "we don't know what's connected" across many device types, Armis's agentless breadth is built for that.

Strong Fit

Mixed IT / IoT / OT estates wanting one platform

Organizations that don't want separate tools per device class. Armis's single-platform span is the consolidation value.

Mixed Fit

Heavy industrial OT environments

Armis covers OT, but for deep industrial protocol parsing and segmentation, an OT-native platform like Claroty may go deeper. Worth comparing.

Less Likely

Teams needing NAC enforcement as the lead

If active network access control and device quarantine drive your requirements, Forescout is shaped for that. Brief Forescout instead.
