I am impressed with the ease at which I could configure the security of my wordpress site with this tool. I especially liked the 2-factor Auth support, specifically the support for hardware tokens (yubikey) was what set this plugin apart for me. I am new to wordpress, but not to internet security so I really can see the effort that has been put into Shield Security.

I understand there is really no way to make your site be immune to hacking or spam, but this plugin really helps lower your attack surface. So now I just have to worry about my site content, and not the constant threat of bad actors.
