New suggestion

I am impressed with the simplicity that started this plugin and how you have been adding new options, in addition I have tried others and they have problems with WordPress 3.8, great job, congratulations

I would suggest the inclusion of a SPAM system in the security module as it would have 2 less active plugins on my website

I also wanted to know if the plugin has been tested with Wordfence Thanks
