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.

Top-level taxonomy

Section Categories
Devices Computers · Hypervisors · Hosted hypervisors · SNMP devices
AWS Cloud resources audited from an AWS Segment
Azure Cloud resources audited from an Azure Segment
Google Cloud resources audited from a Google Cloud Segment

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

Computers

Physical or virtual general-purpose computers audited via WMI/WinRM (Windows), SSH (Linux/macOS), or via an Audit Agent installed on the endpoint.

Subtype Audit method Notes
Windows computer Audit Service (WMI / WinRM) or Audit Agent Requires Windows credentials in the Audit Service pool, or an installed Audit Agent.
macOS computer Audit Service (SSH) or Audit Agent Uses the Linux and macOS credential type (single combined type covers both OS families).
Linux computer Audit Service (SSH) or Audit Agent Same Linux and macOS credential type as macOS.

Hypervisors

Hosts that run virtual machines and expose a management API.

Subtype Status Notes
VMware ESXi Supported end-to-end Requires Hypervisor credential.
Microsoft Hyper-V Taxonomy only Appears as an Inventory category and as a chart source class; end-to-end discovery / audit / credential support is not verified.
Citrix Hypervisor (XenServer) Taxonomy only Same caveat as Hyper-V.
Xen Taxonomy only Same caveat as Hyper-V.

Note: Confirm hypervisor end-to-end support per deployment before relying on Hyper-V, Citrix Hypervisor, or Xen subtypes.

Hosted hypervisors

Workstation-class virtualization software running on top of a host OS.

Subtype Notes
VMware Workstation Hosted-hypervisor subtype.
Oracle VirtualBox Hosted-hypervisor subtype.

SNMP devices

Network devices managed via SNMP v1, v2c, or v3 (with SHA-2 authentication available in v3).

Subtype Notes
Printer Supported end-to-end. The device form shows a Printer supplies tab in place of Details.
Switch Supported end-to-end. Network Map (per-switch topology with PDF / PNG export) is reachable for Switches.
Other Generic SNMP device that does not fit the Printer or Switch subtypes.

AWS resources

Cloud resources audited from an AWS Segment via the AWS API. The Inventory landing page exposes the following AWS subtypes:

Subtype Notes
Resources All AWS resource types in scope.
EC2 instances Virtual machine instances. Supported end-to-end.
Amazon Machine Images (AMIs) Images used to launch EC2 instances.
Subnets VPC subnets.
Zones Availability zones in scope.
Database instance RDS instances.
Key pairs EC2 SSH key pairs.
Network interfaces ENIs.
Load balancers ELB / ALB / NLB.
S3 buckets Object storage buckets.
Virtual private clouds VPCs.
Security groups EC2 / VPC security groups.

Azure resources

Cloud resources audited from an Azure Segment via the Azure API.

Subtype Notes
Resources All Azure resource types in scope.
Application gateways Layer-7 load balancers.
Load balancers Layer-4 load balancers.
Network interfaces NICs.
Public IPs Public IP address objects.
Resource groups Logical containers for Azure resources.
Security groups Network security groups.
Subscriptions Azure subscriptions in scope.
Virtual machine instances Azure VMs.
Virtual networks VNets.
Volumes Managed disks.

Google Cloud resources

Cloud resources audited from a Google Cloud Segment.

Subtype Notes
Resources All Google Cloud resource types in scope.
Big table Bigtable instances.
Images Compute Engine images.
Load balancers Cloud Load Balancing.
Public IPs External IP addresses.
Security groups Firewall rules / equivalent.
Subnets VPC subnetworks.
Virtual machine instances Compute Engine VMs.
Virtual private clouds VPC networks.
Volumes Persistent disks.

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. Hypervisor subtype (e.g. ESXi) follows the management API used. 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.
