TL;DR: Unmanaged assets create blind spots that attackers exploit through unknown devices, forgotten cloud instances and shadow IT, according to Lansweeper. Security teams need continuous discovery because point-in-time inventories cannot govern fast-changing estates.
Editorial analysis by NHI Mgmt Group, based on content published by Lansweeper: “The Vulnerability You Don’t Know You Have: Unmanaged Assets in 2026”.
Key questions
Q: Why do unknown assets create identity governance risk?
A: Because every unmanaged asset can carry credentials, service access, or delegated trust that sits outside normal review cycles.
Q: How does attack surface management help with unknown devices?
A: Attack surface management helps by continuously finding externally reachable devices, services and cloud resources, then mapping them to known owners and approved inventories.
Q: How do I find unmanaged assets before attackers do?
A: Use continuous discovery across cloud, endpoint, network and DNS telemetry to build a living inventory of hosts, services and external IPs, then compare it with CMDB and cloud account records to flag unmanaged assets.
Practitioner guidance
- Build a continuously refreshed asset inventory Use automated discovery across IT, cloud and OT so that every device, application and system is tracked with current status and ownership.
- Classify unknown assets by exposure and business criticality Prioritise unmanaged systems that are internet-facing, old, or tied to sensitive data and credential stores.
- Extend access review to unmanaged systems Validate whether forgotten servers, SaaS tools and remote endpoints still hold service accounts, tokens or other active access paths.
Bottom line: Unmanaged assets matter because they are invisible to patching, logging and access governance, which turns ordinary systems into quiet entry points.

Unmanaged assets are a visibility failure before they are a threat failure. Security teams often describe the problem as shadow IT or weak discovery, but the deeper issue is that governance cannot operate on assets it cannot reliably enumerate. When discovery is incomplete, ownership, control assignment and risk prioritisation all degrade together. The practical conclusion is that asset visibility has become a prerequisite for every downstream security decision.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should teams do first when an unmanaged asset is discovered?
A: First, isolate the asset from unnecessary network paths and determine whether it carries credentials such as API keys, tokens, certificates or service account secrets. Then identify the owner, scope and business function, because an unmanaged asset with valid credentials can still access data, cloud resources or internal services until it is revoked or re-enrolled.
