CSF firewall is available free and most cPanel users might have a copy because it is free? Today, I’m sharing my experiences. Not on how you install CSF or what are the items but opinions on hows the firewall serves its purposes.
For the last decade, CSF has been the part and parcel of cPanel users. However, I’m not actually fond of installing CSF. It is not that CSF has not served its purpose, it is all about individual perception and expectation. why? Let me shares;
a. I have seen CSF in test mode since day one. If you have installed CSF, you will know CSF is in TEST mode by default.
b. Block everyone in the office, cannot send and receive emails. So if your coworkers are sharing the internet through the same router, shared public IP address will be blocked if someone has entered the wrong password a few times.
c. No or non-optimised settings on CSF. Users have left the settings by default or minimum settings were done because they are difficult to understand in layman terms.
So, my experiences are never good with CSF installed. 90% of the time, require troubleshooting if someone has installed CSF. If you have a fully managed hosting service or you have planned to sacrifice your personal time (as they can be very time consuming) to adjust and tweak it.
