Zscaler, a company founded by security expert Jay Chaudhry, filed with Jay Chaudhry, who, in the past 10, founded Airdefense and later sold Motorola, founded CipherTrust and sold it to secure Computing, founder SecureIT later sold to VeriSign, he also founded the Coreharbor and eventually sold to Usinterworking.

Zscaler's business is to help companies free themselves from the annoying, costly WEB filtering and network controls that are replaced by a "cloud", monthly payment model. Zscaler can be viewed as a Web proxy that intercepts all incoming and outgoing traffic from users to check for potential dangers or breaches in these Web activities (in this sense, Zscaler can be sold to GFW-translators in the future)

Zscaler has a group of network security experts who are responsible for designing very detailed security policies for different customers, such as which websites employees can visit and when they can. For example, there is a company whose marketing staff can visit YouTube at lunchtime, and further, they can only upload 2MB of video data per day. Engineers are not allowed to visit Facebook, and others can, for example, have no access to MySpace, and so on.

When Scaler encounters an unfamiliar web site, it immediately uses a technology called "Dynamic content Classification" to analyze the content of the Web page, so that when an employee steals even a strange video station, the boss can find it.

Zscaler regularly provide customers with detailed access reports that you can see which employees spend too much time on social networks, and that companies can monitor their online habits. Chaudhry said these monitoring techniques are not intended to prevent WEB 2.0 applications, but rather to manage them, allowing employees to access the network properly, as long as there is no unrestricted access.

Gartner analyst Arabella Hallawell says she knows that many companies want to use this "cloud" based Web filtering service, and that the market's competitors include ScanSafe and message Labs. Many companies have branches all over the world, and it is difficult to buy and deploy access control software across the global branches, and traditional web filtering software cannot filter malicious code in the Web site to monitor employee information.
