⚠️ Important: For each agent that you install, you must have a license available, or the machine(s) won't show up on your targets page. (eg. If you're installing the agent onto 10 machines, you must have 10 licenses available.)
ℹ️ Note: Each machine must have a unique device name. If you use the same name as an existing internal target, it won't link.
Step 1: Download the agent installer
1. Head to the targets page > select Add target > Internal targets:
2. Choose between a Single agent deployment (providing instructions and a link to download the agent for the machine) or Mass deployment (providing the parameters you need for your installation script):
If choosing Single Agent deployment
3. Enter the details for the machine you wish to scan:
👉 Operating System
👉 Operating System version
👉 Your device name (this must be unique and contain only letters, numbers, or hyphens)
👉 Tag(s) (optional)
➡️ Hit 'Download agent'
You should see something similar to this:
Step 2: Install the agent
Double-click on the .dmg file and then double-click the "Install Nessus Agent.pkg" installer. Follow the steps on the machine to complete the installation process.
Step 3: Install the agent
👉 Open Terminal
👉 Copy the command and run it
If you see a prompt for a password, enter your computer's password and hit return. (Don't worry that you may not be able to see any of the characters that you're typing – this is normal).
When the linking command has run successfully, you'll see this 👇 :
👉 Once linked, it'll look something like this:
