Web 2.0 trends—from social and business networks to user-generated content—create both opportunities and challenges for today’s organizations. Users are no longer just the consumers of web content; they are now the creators. This provides marketing opportunities and increased productivity. However, without the appropriate controls, this can also create liabilities for organizations when their employees publish inappropriate or confidential content on blogs and social networks. Furthermore, the use of rich multimedia applications, such as audio and video streaming technologies, can negatively impact the network performance of the entire office—instantly affecting productivity.
Zscaler’s high-speed, dynamic content classification improves resource utilization by providing granular control of Web 2.0 applications.
Using both URL databases and patent-pending Dynamic Content Classification (DCC) technology, Zscaler offers URL filtering. Organizations can mitigate the legal liabilities associated with sites such as gambling and adult content, cut bandwidth costs by preventing access to audio and video streaming, and eliminate the security risks of embedded malware.
Zscaler provides a unique solution to manage access to Web 2.0 applications. The answer is not to block access completely, nor is it to allow unrestricted access. The solution lies in providing managed access. Zscaler allows organizations to create flexible and granular web access policies by action, location, and group.
For example, organizations may choose to:
  • Allow selected Webmail applications, but block users from attaching files, which usually risks data leakage.

  • Allow all employees to access and view social networks for an hour a day, with the exception of marketing, which can view & publish on social networks such as Facebook to promote communities of interest.

  • Allow employees to view videos & listen to audio on streaming media sites for a maximum of 50 Mbs per day, but prohibit uploading content during office hours.

  • Allow certain instant messaging applications for chat, but prevent file transfers.
Traditional products that allow organizations to control bandwidth by protocol are no longer useful: over 70% of today’s traffic is HTTP. Zscaler enables organizations to control bandwidth by different HTTP applications. Policies can be created for specific HTTP web applications. For example, one organization may decide that financial applications such as NetSuite.com should be allocated a minimum of 10% and a maximum of 50% of the network bandwidth. Similar policies can be defined for sales applications (Salesforce.com), VOIP (Skype), and other web applications. This allows the most efficient allocation of bandwidth.
Zscaler allows organizations to leverage Web 2.0 access to promote sales and increase customer satisfaction while eliminating Web 2.0 liabilities and challenges. It improves the utilization of network resources, by minimizing the use of bandwidth-hog applications, and of human resources, by limiting time-wasting activities and improving employee productivity.
