PHP Guard Dog gives a website administrator a simple solution to an important problem: security. If you have sensitive information floating around on your website, it is available to any Internet user who stumbles upon it. You probably hope that the wrong people (like hackers) won't happen to find your unsecured data. PHP Guard Dog offers a simple, concise way to protect that information to only one person, or perhaps a handful of internet users. You can protect your content to any combination of users and groups in mere seconds.
