Attackers are no longer targeting Web and email servers. Today, they are attacking enterprises from the inside out, by first compromising end-user systems and then leveraging them to gain access to confidential data. As such, it is imperative that organizations have an understanding of what is happening on the Web. As a cloud-based security vendor, Zscaler has a unique perspective on Web traffic. With millions of end users traversing the Web through Zscaler’s global network of Web gateways, they are able to understand both how users are interacting with Web-based resources and how attackers may be targeting end users. This slideshow highlights finding from their “State of the Web” research report.

More than 25 percent of corporate users are running old, insecure versions of popular browser plug-ins — such as Java, QuickTime, and Adobe Reader — creating an easy target for attackers.

Seven in ten enterprises block at least some Web content based on category, with social networking being the most common category blocked.
