For the price and for the features – the number one WP security plugin out there.

Guides you very nicely through the maze of WP security and hardening options, which to non-experts can be bewildering.

The recommended settings will get you a very long way, but as always, the best results only come if you actually put an effort into understanding what goes on behind the scenes in terms of how Shield is protecting your site, what counter-measures to enable and where to back down a bit.

Security is hard – Shield makes it easier – highly recommended.
