Just installed it after the worldwide warning today.
The tour is quite a read out for dummies like me...
But even I managed to understand the beautiful secrets of Wordfence.
Well, now we are more than a year further. And I can tell you this plugin is a GEM!! It works axactly like you want it.
In april 2016 with a big upgrade to a FANTASTIC firewall, some of us (me too) had some trouble with a blanc display (while WF worked perfectly - only not visible), but the support was SO GREAT!!!
It turned out to be a conflict with other plugins who were not compatible with the newest WordPress.
So be SURE all your plugins are compatible with your WordPress version.
