For each agent that you install, you must have a license available; if you don't, the machine(s) won't show up on your targets page.

👉 If you're installing the agent on 10 machines, you must have 10 licenses available.

Please note, each machine must have a unique device name; if you use the same name as an existing internal target, it won't work.

Step 1: Download the agent installer

1. Head to the targets page > select Add target > Internal Targets

2. Enter the details for the machine you wish to scan:

👉 Operating System
👉 Operating System version (there is only one option for macOS)
👉 Your device name (this must be unique and contain only letters, numbers or hyphens)
👉 (optional) Add any tag(s)

➡️ Hit 'Download agent'

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.

👉 Open terminal

If you see a prompt for a password, enter your computer's password and hit return. (Don't worry that you can't see any of the characters that you're typing – this is normal).

👉 Once linked, it'll look something like this:
