Summary

The purpose of this guide is to help you install a Nessus Agent on a Windows operating system and link it to your Tenable.io account. This guide covers the prerequisites, Nessus Agent installation process, and configuration of a Nessus Agent scan. Tenable does not recommend using this guide for larger Nessus Agent deployments, but rather for one-off testing scenarios against a small subset of assets.

Prerequisites

First, you need to download the Nessus Agent, which is available on our Tenable Downloads site. There are many supported operating systems, but this guide focuses on a Windows installation.

You also need to know how to locate your Tenable.io linking key. You can find your linking key in your Tenable.io account in the Sensors section. For more information, see the Tenable.io User Guide.
