Ultimate Security Checker


#1 SECURITY PLUGIN for WordPress! We’re the only plugin that gets updated regularly to protect against the latest threats! Why trust your work to a plugin which hasn’t been updated in months or years?

Every day, hackers take over WordPress installations and delete the user’s data and blog posts and use their servers for illegal activities. Don’t be a victim – we’ll help you prevent getting your thousands of hours of hard work on your blog taken over by a hacker and deleted.

Our plugin identifies security problems with your WordPress Installation. It scans your blog for hundreds of known threats, then gives you a security “grade” based on how well you have protected yourself. You can fix the problems yourself, or you can use our help to do it for you automatically.

Our plugin and service is designed to be used by anyone from a complete newbie to an advanced PHP engineer.

Appears to be abandoned by the author. This is a good plugin when it was fully functional, but I’ve found that it has aged out and is identifying issues that don’t exist. The concept was excellent when it was being maintained, but the author has abandoned it.

My client site suddenly broke for no apparent reason. Digging in to the logs, voila! this plugin was the culprit!!! I tried to update our WordPress version but this plugin is stopping us… finally i found an alternative solution!
