I would like to suggest a feature I think would be usefull for A LOT of sites. For all my websites I'm using the email address encoder plugin (https://nl.wordpress.org/plugins/email-address-encoder/) A great plugin, it does what it says, scramble the email addresses so that bots can't read them and spam your mailbox.
I think this could be a feature added to the WP Defender plugin? It's not really 'defending' your website from hacks so much. It is however defending you from spam.
I'd like to see a simple checkbox, which would add this feature. This way my websites would need 1 less plugin installed. And it would make your product a little more complete!
