More updates to deal with web threat

Blue Coat has increased the frequency of updates from the WebPulse service to the ProxySG appliances from 20 minutes to every five minutes because of rapidly spreading Web-based threats. In less than six months, requests to the WebPulse service have increased by 50 percent to more than 150 million per day. With faster update cycles, ProxySG appliances can more quickly recognize and block malware hosts and attempted attacks that have been identified by the Blue Coat WebPulse service.

"As threats proliferate across the Internet, it is important that enterprises have a multi-pronged defense strategy that both identifies the threats and rapidly protects against them," said Bethany Mayer, senior vice president of Worldwide Marketing at Blue Coat. "Blue Coat delivers that protection to its customers by utilizing the community power of WebPulse to rapidly root out malware and other threats."

WebPulse continuously updates Blue Coat WebFilter with detected malware hosts and new content ratings based on inputs from ProxySG appliances, ProxyClient and K9 Web Protection, the company's free Web-based security service for families and individuals.  With over one billion user requests per week, the WebPulse service analyzes a large volume of traffic on popular and unrated sites using multiple threat engines, machine analysis and human raters to detect malware and rate new Web content. As a cloud-based service, WebPulse is a cost-effective way to build a large community of users that shares information on detected malware.
