I'm a big fan of Wordfence. I have been using it for several years and I am very happy with it. It's available as both a free (probably good enough for most sites) and a paid version.
On top of the quality of the product, they participate in the WordPress community and host a podcast covering computer security and WordPress.
Have to say I agree, WordFence is a good one.
Any one that changes your login URL. It’s a simple thing to do that makes all the difference in the security of your WP.
Nice. Definitely a good and simple measure to take.
