About WHMCS Firewall

WHMCS itself is a secure platform. However, it always helps to add some extra security, auditing capabilities, secure offsite backups (Amazon S3 + DropBox) and a web application firewall to your WHMCS install by using a security module that enforces good security practices. WHMCS manages your customers, income from products/services and company reputation so it is easy to see the need to make your WHMCS installation secure as possible!


WHMCS Firewall is compatible with WHMCS v5.x and v6.x - select your WHMCS version during checkout and install the matching module.


1. Web Application Firewall + IDS * Htaccess based firewall, pre-loaded rules and notifications to keep your updated on the latest threats to your WHMCS website.

2. Amazon S3 Backups * Allows secure offsite backups (manual or scheduled) to your Amazon S3 file storage account.

Bought it. It is not supported with the most recent version of Firewall. Just wasted $70 dollars. They won't even respond to me.

If you operate a WHMCS environment, WHMCS Firewall is a must have utility. The system automates many of the task that an administrator would validate and verify.

The application has been flawless and support have been timely and insightful. I highly recommend WHMCS Firewall for those who are serious about security!
