We realized there was a gaping hole in existing Web security products. While traditional security companies had gotten relatively good at addressing technical threats like viruses, they were failing to prevent a new breed of "social engineering" tricks like spyware infections, identity theft scams, and sites which send excessive e-mail.

To address this challenge, we built a system of automated testers which continually patrol the Web to browse sites, download files, and enter information on sign-up forms. We document all these results and supplement them with feedback from our users, comments from Web site owners, and analysis from our own employees.

Our easy to use software for Internet Explorer and Firefox summarizes our safety results into intuitive red, yellow and green ratings to help Web users stay safe as they search, browse and transact online. Our goal is to pioneer a new approach to Web safety and make the Internet safer for everyone.
