Welcome to the Tenable One Asset Categorization Quick Reference Guide

Last updated: February 02, 2026

Asset categorization is a framework that can be used to classify assets in a network. The first phase focuses on asset classification while future phases will provide richer context about the asset; e.g. asset ownership, administration and location. The framework is designed to be transparent, extendable, and explainable and to produce a holistic (“global”) category of an asset.

In the Tenable Exposure Management user interface, you can view the profile of an asset via the Asset Details page.

Framework

Where possible, each asset is assigned an Asset Category and an Asset Function. A category is meant to answer the question: “What is this asset?”.

In the current framework, each asset belongs to only one of the following categories:

• Cloud

• Compute and Application Server

• Compute and Application Server VM

• Healthcare

• Internet of Things

• Legacy device

• Network Infrastructure

• Network Infrastructure VM

• Operational Technology

• Peripheral

• Personal Computing

• Telecomm

• Undefined

• VM or Workload

A category captures the fundamental similarity between all assets that belong to the category and can be used for clustering. While the category label captures fundamental similarity between the assets in a category, the different asset functions within the category capture the fundamental differences between the assets in the category.

Asset functions answer the question: “What does the asset do? Or what functionality does it provide?”

Each asset can have one or more function labels as assets can be multi-functional. Assets within a functionality label share fundamentally similar attributes. Additionally, each Asset Category includes a set of Asset Function labels. For more information, see Asset Categories and Functions.
