WP/BP site security


I have a BP site that hackers seem to love to mess with. It seems like it is time to take more serious steps to protect the site.

I wish there was a WPMU solition, but maybe I’m missing something so I’m asking.

I’m also asking for recommendations.

Does anyone have experience with WebsiteDefender or a competator? I don’t see anything specific with this tool for BP tho there is a WP plugin.

Any help would be appreciated.
