The WHMCS Firewall security meter feature is a numeric score that gives you an average of how secure your WHMCS install is at any current time.

View your security score by following the steps below:

Login to your WHMCS > hover over the menu tab ADDONS > click on FIREWALL MANAGEMENT > you now see your Security Meter score on the top left of the firewall dashboard > hover over and click on your SCORE > view the list of all items required to increase your security and score.

Resolving active “Critical” and “Warning” alerts are the best way to increase your score.
