Yes, FireWall Script is encoded using ioncube. In most cases your server will already be setup to run ioncube-encoded scripts, or uploading the included /ioncube/ folder will allow the scripts to be run, without any configuration on your part. In some cases, however, you will need to have your server admin "install" ioncube (*installing ioncube involves editing the php.ini file, and usually restarting Apache afterwards).

Please be aware of this before purchase. No refunds will be issued on the basis that you do not wish to (or are unable to) run ioncube-encoded scripts.
