Device Types Reference

The full taxonomy of devices that AlloyScan can place in Inventory. Categories mirror the sections shown on the Inventory landing page (Inventory) and the type-specific grids reachable from each card.

Preview: AWS, Azure, and Google segments are Preview features. Behaviour and supported subtypes can change between releases.

Computers

Physical or virtual general-purpose computers can be audited agentlessly through an Audit Service or by an Audit Agent installed on the endpoint.

Subtype Audit method Notes
Windows computer Audit Service (WMI / WinRM) or Audit Agent Agentless audit uses credentials of the Windows type.
macOS computer Audit Service (SSH) or Audit Agent Agentless audit uses credentials of the Linux and macOS type.
Linux computer Audit Service (SSH) or Audit Agent Agentless audit uses credentials of the Linux and macOS type.

For credential fields, supported versions, and platform requirements, see Credential Types Reference and Supported Targets.

Hypervisors

Hypervisors are hosts that run virtual machines. AlloyScan supports full hypervisor inventory collection for VMware ESXi through an Audit Service.

Subtype Audit method Notes
VMware ESXi Audit Service (ESXi API) Uses credentials of the Hypervisor type and collects host and virtual-machine information.
Microsoft Hyper-V Audit Service (WMI / WinRM) Uses credentials of the Windows type.

For credential fields, supported versions, and platform requirements, see Credential Types Reference and Supported Targets.

Linux-based hypervisor hosts, such as Xen hosts, can be audited as Linux computers through SSH or an Audit Agent.

SNMP devices

Network devices managed through SNMP v1, v2c, or v3, with SHA-2 authentication available for SNMPv3.

Subtype Audit method Notes
Printer Audit Service Agentless audit uses credentials of the SNMP type. The device form shows a Printer supplies tab in place of Details.
Switch Audit Service Agentless audit uses credentials of the SNMP type. Network Map is available for switches.
Other Audit Service Agentless audit uses credentials of the SNMP type. Generic SNMP device that does not fit the Printer or Switch subtypes.

For SNMP credential fields and target requirements, see Credential Types Reference and Supported Targets.

How devices are categorised

The category and subtype assigned to a device are derived from the audit snapshot's data and from the segment that scanned it. Computer subtype (Windows / macOS / Linux) follows the audited OS. Full hypervisor inventory collection is supported for VMware ESXi. SNMP subtype follows the SNMP sysObjectID and the matching keywords in the Manufacturer registry. Cloud subtype follows the cloud provider and resource type returned by the cloud API.

Constraints

  • Manual device add is not implemented. Devices appear in Inventory only after they are discovered and audited.
  • Mobile device audit (iOS / Android) is not implemented.
  • The Inventory landing page hides empty categories by default. Toggle Show empty to display every category regardless of count.
