Just a shout out for the Danami support team. We decided to try Juggernaut on a server we were migrating purely in hopes that it would supply some GEO blocking security. Now over a year later it's done everything we hoped, and more. We're now using it to deal with some other security issues, and the Danami support team has been great.
We're not usually big on subscription based products, but this one has proven itself. So much so that when our AV comes up for renewal this year, we will likely be switching to the Danami product for that as well. When first looking at the firewall, it seems to be a bit overwhelming, but I have found that it's really not once you start using it.
If you're looking for a good software based firewall add on for Plesk that will provide GEO Blocking, this is a great product. I hope this helps others who are looking for a solution.
