Liongard Agents

Liongard On-Premises Agent Versions

Liongard will periodically upgrade our On-Premises Agent Version.

As of May 2022, the most up-to-date version of Liongard's On-Premises Agent is Version 3.2.4. This agent has auto-upgrade capabilities built-in, and the details can be found here.

Liongard Agent Service Account Password Limitations

The password applied to the Service Account used with Liongard cannot exceed 128 characters.

Inspector Versions

Latest (Auto-Update) Version

Liongard recommends that all partners set all Inspectors to the "Latest (Auto-Update)" version. This ensures as Liongard improves Inspectors, users get the most up-to-date Inspector version.

Legacy Inspector Versions

In the case that Liongard upgrades an Inspector Version, Liongard will offer support for the older Inspector Version for six months after the updated version is released.

Liongard will cease to push any updates to outdated Inspector Versions once the updated version is released.

Software Versions for Inspectors

Liongard seeks to support all software versions for any System Inspector; however, there are limitations. Please see below for the System Inspectors with known version limitations as well as additional information on the scope of our Inspectors:

System Inspector

Supported Versions

Active Directory

The Active Directory Inspector has limited support when run against domain controllers running Windows Server 2008 R2 or older operating systems.

This Inspector does not support "local inspections" (i.e., when the Liongard Agent is installed on the domain controller itself) for pre-2012 OS versions.

"Remote inspections" where the Agent is installed on another server with a newer OS version are possible but require Active Directory Web Services on the target domain controller. ADWS was not included by default on older versions of Windows Server and must be installed separately and at your own discretion.

For more information, please review this documentation

Barracuda Firewall

The Barracuda Firewall Inspector does not support clusters.

Cisco IOS

The Cisco IOS Inspector does not support the Cisco Small Business Series.

Fortinet FortiGate Firmware Version

Liongard supports Fortinet FortiGate firmware version 6.2 and later. We will support versions less than 6.2 on a reasonable-effort basis

The Linux Inspector is only officially supported for Ubuntu and Red Hat distributions. Other distribution packages may or may not return a full data set.


You must have standalone access to the SentinelOne cloud portal for our Inspector to run. If SentinelOne is integrated with your RMM and has no access to the cloud portal, our SentinelOne Inspector can't be used.
