You never know how good a security suite will be until it saves you from a security issue or you have to find a way to deal with it.
That said, like other reviewers, I was disappointed to find out that the software I purchased is hobbled in that there is no central dashboard except for a separate paid plugin to tie WP Security Ninja to MainWP.
So if you use a different site management tool than MainWP, you're SOL.
Well good thing I use MainWP. So I follow the directions to install the plugin and WHOA, what, I have to pay for it??? The only time I figured out that it was a separately paid plugin was AFTER I installed it on my MainWP site and on my satellite site. What a waste of time! Just state in your deal terms: "This deal DO NOT INCLUDE any way to monitor or control your security from a central location. (and you will have to log into every site to run it or see the results.) (yes you can get email reports on failure - that doesn't count).
Apparently, they've released some free features in that plugin but we'll have to see when they revoke them - apparently after they are done building it.
Other than that, it's actually quite pleasant to work with. It caught some minor things that other software missed. Bravo.
