Wordfence Security Plugin
Excerpt via http://wordpress.org/plugins/wordfence/
Wordfence Security is a free enterprise class security and performance plugin that includes a very fast caching engine, firewall, anti-virus scanning, cellphone sign-in (two factor authentication), malicious URL scanning and live traffic including crawlers. Wordfence is the only WordPress security and performance plugin that can verify and repair your core, theme and plugin files, even if you don’t have backups.
Wordfence Security is 100% free. We also offer a Premium API key that gives you access to our premium support ticketing system at support.wordfence.com along with two factor authentication via SMS, country blocking and the ability to schedule scans for specific times.
With the ever increasing number of website compromises, we are updating our security not only on the server where your site is hosted, but adding precautionary features such as the Wordfence Security plugin to fend off hackers. All Premium Package Hosting Accounts also have the added bonus of being backed-up on a third-party cloud server in the event something were to happen.
