2014: There was a little blip of trouble when iThemes took over this plugin, but after a difficult few days, the problem was resolved. The Security plugin is performing at least as well as its predecessor. Thus my earlier comments still hold:

This plugin has been working very well. I get regular updates on changes to my site via email. I’ve had a flood of “new subscribers” (that is, addresses that want to log in and do mischief) on the site, and Better WP Security points them to a 404 page; end of problem.
