There are some plugins that get installed on every new WordPress site I build, and this is definitely one of them.
– It protects your site from brute force login attempts
– It screens incoming data to prevent hacking attempts
– It prevents spam bots submitting comments on your site
– It keeps a log of actions and changes made to your site for analysis
And more! and what’s great is it does all this without any affect of site performance.
Just install it, turn it on and forget about it.
