Agents in Invicti Enterprise On-Premises

This document is for:

Invicti Enterprise On-Premises

To scan a website located on your internal network, you need to install and configure a scan agent on your network. The agent will conduct the actual scan job and then report the results back to Invicti Enterprise.

You can install scan agents in Windows and Linux and use the dockerization version of the scan agent. These agents execute scans and inform the Invicti Enterprise application.
In addition to the scan agent, you can install an authentication verifier agent that will verify the form authentication on your website.

You can find agents’ installer files in the InvictiEnterprise.zip file you were emailed. OR, you can download them from the Invicti Enterprise user interface.

This topic explains how to download scan and authentication verifier agents from the Invicti Enterprise user interface and explains how to manage agents.
