Software firewall configuration

[Mick Haller]

Hello

Is there any centralized firewall system that can be installed on a normal hosting account. Currently I have several WordPress sites with RSFirewall components installed and I am constantly receiving notifications that some people are trying to guess user names & passwords to the admin section of the website.

I'd like to be able to log into one location and include the offending IP address and have it to propagate out to all my hosting accounts. I am currently updating .htaccess file on all my hosting accounts, but this is very time consuming. If anybody has suggestions free or paid it would be much appreciated.
