A new company is offering a security filter in the cloud. Zscaler, a Santa Clara, Calif.-based company headed by a veteran security entrepreneur, unveiled its hosted filtering service on Monday.
With the Zscaler service, companies don't need to maintain their own Web filtering and security software on their servers. Instead, as with many other areas of business software, the filter is based "in the cloud" -- that is, on the Internet.
Enforcing Company Policies
Zscaler said its service "will change the way businesses allow users to access the Internet by providing the right access to the right users, from any place and on any device."
As with a Web proxy, the globally-based infrastructure screens all HTTP traffic incoming and outgoing, looking for malicious software. It can also scan for activity that could run counter to a company's stated policies.
A company's IT department can use Zscaler's network controls to enforce its policies, such as limitations on the kinds of sites, the times when they can be visited, and the kinds of bandwidth-clogging things users might do. Web 2.0 applications, such as social networking, blogging, Webmail and IM, can be identified and managed.
The software-as-a-service approach also addresses what Zscaler said is the insufficient effort many companies have instituted to deal with user-initiated traffic, as well as the coverage problems offered by on-the-road service and sales people.
The Zscaler service redirects traffic to and from a company to one of its data centers, and Web pages are returned after they have been inspected by the software. The service provides protection against bots, malicious content, phishing and peer-to-peer networks.
Zscaler said its software performs inspections at 40 times the speed of most of its competitors, thus avoiding major delays. The company said each of its gateways can process 250,000 transactions per second, up to 100 times faster than other...
