Great Free & Pro Version

This is a great plugin for securing and monitoring your WordPress website. I have the free version installed on around 20 sites and the Pro Firewall through custom Name Servers on a handful of other sites (Pro costs around $199/year per site at the time of this review). I most often use the default version of the plugin for monitoring and logging with my own custom .htaccess rules and .htaccess firewall for hardening.

NOTE: Be careful when setting up functionality and hardening your settings through the plugin. Most of the 1* reviews are from people breaking their sites and getting themselves locked out by not understanding what the plugin settings do/affect and how to properly use the plugin’s settings. When in doubt, don’t enable every single security setting and just use the bare minimum until you back test your own site.
