Highly configurable, without the bloat of other security plugins

Sucuri strikes a good balance between security features and ease-of-use. I am a recent convert from Acunetix. Very configurable, and much easier to setup than other Plugins, like Better … and Wordfence.

I particularly like the login and content editing monitors, as well as the dashboard hardening checklist. I would give it 5 stars, but only time will tell how effective it is.
