CSF allows you to modify your iptables rules within WHM interface. As a comprehensive security siute, Cloudlinux has an imunify360 product that needs to be subscribed separately.
By default, there isn't any different firewall tool with CloudLinux as that uses whatever you were using with CentOS. I do like CSF as that lets you do things through WHM or command line, but there are many other tools such as Imunify like @kodeslogic mentioned.
