Wordfence Security is a free enterprise class security and performance plugin that makes your site up to 50 times faster and more secure.
Works beautifully, I've been a user for over a year without a single problem and my site is secure.
Provides a whole whack of extremely useful functionality.
We recommend that this plug-in be installed on every site that we are involved with. As a security plug-in, it is fantastic in its own right, but now they have created their own caching engine inside Wordfence. It is called Falcon, and it's easy to setup and works great. We have not seen any problems with it thus far, after enabling it on several dozen websites. Nice work, Wordfence!!
The new performance (caching) controls are great! No longer have to use a third party caching plugin, this one does it all.
Thank you for this important plugin.
This is a great plugin for all websites to have. Stops the "bad guys" from accessing your site. A must have for anyone running WordPress!
. . . and (just as importantly) doesn't create conflicts.
Great protection. Blocks bad behavior on my sites regularly.
