Agents Overview

What is a Liongard Agent?

Liongard gathers information about your Environments, customer networks, and cloud systems via Agents. Agents run Inspections, which are the individual queries that gather information about various systems (the Active Directory Inspector, the SonicWall Inspector, etc.).

Liongard has two types of Agents. One Agent is used for inspecting devices on your local network, and a Liongard Managed Agent is used for inspecting cloud systems.


Key Concept

Inspectors run on Agents.

Agent Types

Liongard has two types of Agents. A Self-Managed Agent used for inspecting devices on your local network, and a Liongard Managed On-Demand Agent used for inspecting cloud systems.

The On-Demand Agent is managed by Liongard, so we completely manage its setup and maintenance. This Agent runs inspections that do not require privileged access to your customer's networks. We recommend this Agent for most inspectors.

Self-Managed Agents are installed on your customers' network Environments. These Agents are installed on Windows servers "inside the firewall" (preferably on a Domain Controller) to perform inspections that do require access to servers and services that are not available from the public internet.

An Agent will be required per VLAN in order to communicate directly with the system it needs to inspect.

Typically, Agents are installed on the Domain Controller. From there, the Agent will auto-discover the Windows Server Inspector, and once activated, the Windows Server Inspector will auto-discover Active Directory Inspectors. The Agent will also automatically discover a Network Discovery Inspector.

Environment Scope

When configuring an Agent, you can have the option of selecting its Environment Scope. The Environment Scope for an Agent determines the Agent's permission for which Environments it can perform inspections for.

  • Global: Agent can perform inspections across multiple Liongard Environments. This scope is primarily used for Cloud System Inspectors that require a source from a static IP
  • Single Environment: Agent can process inspections for only one Environment

The Admin > Agents screen separates Agents into Self-Managed and Liongard-Managed Agents. Ensure you are selecting the appropriate tab when looking for deployed Agents.

This screen also has clickable buttons to quickly provide insight into Total Agents deployed, Agents Awaiting Configuration, Outdated Agents, and Offline Agents.


For additional information, see our Agent Management documentation.

Installing Self-Managed Agents

You can deploy the Liongard Agent via Liongard's MSI Installer, Command line, or PowerShell script using MSIEXEC, or via an RMM Script.


Agent End of Life

As of April 30th, 2022, Liongard terminated support for Agents older than 3.0.2. Please update your Agents to ensure your Inspectors continue to function properly.


Traffic to your Network/Websites

Please note by enabling Inspections, you will see new traffic from Agent machines depending on the Inspection type. In order to verify traffic you see in your network, or against an external facing entity, is coming from Liongard, check the IP of a specific Agent via the Admin > Agents screen on your Liongard dashboard.
