The Shield Security plugin is just excellent. I started with the free version a few years ago. I upgraded to the paid version quite a while ago and I never regretted that decision. I have been using this plugin for quite a while. It has never disappointed me. It has been keeping all my sites safe and sound since I started using it. The free version is excellent and the pro version is worth the subscription fee which is not much at all. I particularly like the extra features that the Pro version offers. It makes my life easy and I always recommend this plugin without any hesitation.
