TL;DR: Connected-device vulnerability queues mis-rank risk when severity is treated as a stand-in for exploitability, according to Asimily. IoMT, OT and IoT teams need prioritisation that reflects firmware, reachability and network path before they spend remediation effort.
Editorial analysis by NHI Mgmt Group, based on content published by Asimily: “ATT&CK Analysis: How Asimily Determines Which Vulnerabilities Require Action”.
Key questions
Q: What breaks when vulnerability prioritisation ignores network topology?
A: The queue becomes misleading.
Q: How should security teams decide which connected devices to remediate first?
A: They should prioritise devices where exploitability is confirmed by the combination of asset profile, firmware version, exploit availability, and network reachability.
Q: Why does CVSS mis-rank vulnerabilities in IoT and OT environments?
A: CVSS measures severity in isolation, but connected-device risk depends on whether the vulnerable asset is reachable, which firmware version is running, and whether the network path enables exploitation.
Practitioner guidance
- Replace CVSS-only queues with exploitability-based triage Rank connected-device vulnerabilities by device model, firmware version, exploit availability, and network reachability, then suppress findings that lack a realistic attack path.
- Use topology data to drive remediation order Map which devices can actually be reached from likely entry points before assigning work, so the queue reflects operational exposure rather than generic severity.
- Tie segmentation rules to confirmed attack paths Write isolation policies around devices and flows that have demonstrated exploitability in your environment, not around every high-scoring CVE.
Bottom line: Connected-device vulnerability queues fail when severity is treated as a substitute for exploitability.

Severity-first vulnerability queues create exposure blindness: organisations that sort connected-device findings by CVSS alone are not managing operational risk, they are managing spreadsheet order. A severity score describes the vulnerability in isolation, while connected-device risk depends on reachability, firmware specificity, and network position. For IoT, OT, and IoMT, that difference is the difference between noise and exposure.
A question worth separating out:
Q: How do security teams know if exploitation-based prioritisation is working?
A: Look for a shorter must-fix list, fewer exposed KEV items, faster closure of actively exploited CVEs, and clearer ownership for the devices or applications that stay open longest. Good prioritisation reduces the number of exceptions that survive month to month. If the queue still grows without changing which items get fixed first, the model is not working.
