This feature is under construction – v4.0 target release
The Data Feeds in WHMCS Firewall will be a dynamic way for extracting data from the WHMCS Firewall module for use on the pages of your website.

They will allow you to get information out of WHMCS Firewall such as current Security level, Alert descriptions and IP sources (without having to do a manual IP lookup), Historical data into charts, etc. onto the static pages of your site, so that if ever make a change inside WHMCS it will auto update on your website.

*Think monitoring multiple WHMCS websites security status from one location.
