@starmckel your comment is completely wrong.
The plugin is free, otherwise you wouldn’t be able to install it and use it.
There one single feature that is premium, and this is already explained in the description before the installation process starts. I believe you read the description of every plugin install, right? Are you installing random extensions without knowing what do they do? Of course not, that would open security holes in your website.
In the description of the page you can see this Website Firewall (premium).
And in the FAQ you can find this What is the website firewall (premium).
This is not included as a free option of the plugin, but is integrated so that if purchased you are able to activate. If you prefer to leverage the Sucuri Firewall product by itself, you have the option to operate the Website Firewall WordPress Security plugin in standalone mode.
You can still use the other features without paying for the firewall.
Generating an API for the plugin, not for the firewall, is completely free.
