Aviz Networks explains network visibility for IoMT and OT device security

Modern hospitals rely on large numbers of networked clinical and facility devices, many of which lack agent support or patching options. The vendor guide argues that network-level visibility is needed to identify and secure these devices across clinical IT and OT environments.

Research Overview

The guide describes connected devices such as infusion pumps, ventilators, imaging and lab systems, badge readers, HVAC controllers, and telehealth endpoints operating on shared networks. It states that many devices cannot run agents and that some are difficult to patch or are based on legacy systems.

To address the visibility gap, the guide explains how network-level visibility can help healthcare teams understand device presence and traffic patterns across clinical and facility environments. It also frames network observability as the traffic data foundation that supports IoMT, OT, and device security platforms.

Key Findings

The guide highlights full visibility across IoMT, clinical systems, and facility OT devices. It also describes improved device discovery when visibility is paired with tools such as Armis, Forescout, and Nozomi Networks.

It further reports a continuous view of device behavior, communication, and encryption status. The guide also describes detection of abnormal traffic and lateral movement between devices.

Technical Breakdown

The document describes the approach as providing packet-level data through Aviz Networks Deep Network Observability. It characterizes this telemetry as supporting device communication understanding and security use cases for IoMT and OT.

The guide states that visibility is consistent across on-premises, cloud, and hybrid environments. It also describes reduced blind spots in unmanaged and agentless devices based on the network visibility approach.

This vendor guide ties connected device security efforts to network-level visibility and states that packet-level traffic data from Aviz Networks Deep Network Observability supports IoMT and OT security across managed and agentless devices.
