I was a little bit apprehensive - what with yet another WP security plugin - but you know what: it does exactly what it says on the label! The default values are reliable, safe and good enough to start off taking care of most security issues. Also, if you worry about the free version being little more than a stripped version to foist payment for the premium ("pro") version, rest assured: the free version is absolutely great. Of course you get your extra money's worth for justa little extra, but there's no urgent necessity to pony up. All in all, a well-rounded, feature-rich, very useful security plugin to add to your arsenal.
