Blue Coat’s WebFilter and WebPulse service provide businesses with a URL filtering solution for a Web 2.0 world. With more than one billion requests per week from more than 54 million users around the world, WebPulse maintains a timely profile of Web content and provides customers with an important new layer of security at the Internet gateway.
Add comprehensive protection from spyware, phishing, peer-to-peer and viral attacks to your proxy gateways.
Blue Coat’s WebFilter analyzes content, categorizing domain names, directories and IP addresses for policy enforcement and security. With a WebFilter subscription, the vast majority of URLs requested by your users are already covered “on-proxy” with ratings returned in less than eight milliseconds.
WebFilter’s Dynamic Real-Time Rating (DRTR) technology uses artificial intelligence to categorize Web pages “on the fly” the first time a user requests access.
The DRTR service reads the context and evaluates each new Web page. If the DRTR service rates the content with high confidence, it automatically populates the master database and keeps all other Blue Coat products current.
WebFilter’s WebPulse community provides enterprises a comprehensive rating service that analyzes newly published and previously unrated Web content.
If DRTR can’t process the site, it rates content as "other" or "unknown." These sites are pushed through the ad-hoc WebPulse community watch cloud service where humans may ultimately review and categorize the information.
The WebPulse service receives real-time intelligence on new sites, including dynamic Web 2.0 content, from a diverse expanding community.
The Blue Coat WebPulse service is the first cloud-based community watch environment to implement Dynamic Link Analysis. It builds a comprehensive profile of the Web as users encounter dynamic new sites and user-generated content. WebPulse receives more than one billion requests per week from more than 54 million users around the world. The discovery of malware by one member is shared with all.
At the enterprise level, the WebPulse service removes the burden of analyzing all Web content from the Web gateway.
Blue Coat ProxySG appliances check for threat updates every five minutes to update 'on-proxy' WebFilter databases. When the WebPulse service detects malware, the identity of the host is sent to the Blue Coat WebFilter master database. Remote clients receive updates immediately. WebFilter can efficiently block dynamic web requests to malware hosts hidden in popular and trusted Web sites.
