This article describes how to install the agent on a macOS device (we also have installation guides for Windows and Linux):

Step 1: Download the agent installer

Head to the Nessus agent download page:
https://www.tenable.com/downloads/nessus-agents#nessus-agents-7-4-1

Search for NessusAgent-7.4.1.dmg

Download the file and keep a note where you've saved it. 

Step 2: Install the agent

Double-click on the .dmg file and then double-click the "Install Nessus Agent.pkg" installer.

Follow the steps to complete the installation process.

Step 3: Configure and link the agent

To configure each device for scanning you'll need the following two pieces of information:

  1. Device Name:
    To identify your devices as targets for vulnerability scanning in our portal, you'll need to name them according to a specific convention. We provide you with a unique client prefix, which needs to prepend what you want to call your device. So if your device is called paul-laptop and your unique client prefix is DQEGBQUAAAc, the device name should be DQEGBQUAAAc_paul-laptop.
  2. Unique Key:
    A second unique identifier that makes sure your device shows up in the right place - we'll also provide this to you.

Once you have the above information ready, open the Terminal app and run the following command - modifying the placeholders (everything inside [ ] brackets) accordingly:

sudo /Library/NessusAgent/run/sbin/nessuscli agent link --name=[1.Device Name] --cloud --key=[2.Unique Key]
