This article describes how to manually install the agent on a Linux device. If you wish to individually install the agent on your devices, you can use the installation wizard inside the platform.

🚨 IMPORTANT 🚨

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.


Step 1: Download the agent installer

  • Search for the relevant .dmg installer file (i.e. NessusAgent-X.X.X.dmg) and download it.

Step 2: Install the agent

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

Step 3: Configure and link the agent

To configure: Open the Targets page > Add Targets > Internal targets

Click 'View configuration keys'

Copy the 'Prefix'

Your DeviceName is comprised of your Prefix and your TargetName
(what you'd like the target to be named in the portal).

👇
DeviceName = Prefix_TargetName (eg. DQEGBQUAAAc_paul-laptop).

To link:

  • Open the Terminal app

  • Run the following command, making sure to update:

    • DeviceName (see above)

    • Key (see above)

sudo /Library/NessusAgent/run/sbin/nessuscli agent link --name=[DeviceName] --cloud --key=[Key]

Note: Internal vulnerability scanning is only available to Pro and Vanguard customers.
