Wordfence Security is a free enterprise class security and performance plugin that makes your site up to 50 times faster and more secure.
Wordfence starts by checking if your site is already infected. We do a deep server-side scan of your source code comparing it to the Official WordPress repository for core, themes and plugins. Then Wordfence secures your site and makes it up to 50 times faster.
Wordfence Security is 100% free.
