Blue Coat WebFilter Controls web access and stops the latest web threats in real time.

Blue Coat WebFilter, with its cloud-connected architecture and inputs from a worldwide community of users, is best-in-class for web threat protection. Blue Coat WebFilter protects user productivity, blocks malware downloads and web threats, and enables compliance. WebFilter is continuously updated by the WebPulse collaborative defense that detects hidden malware and provides reputation and web content analysis.

WebFilter provides deep analysis ratings on more than 300 million daily web requests by leveraging the WebPulseTM cloud defense, which provides more than seven billion ratings per day from 70+ million users. As a result, WebFilter can effectively block malware downloads, web threats, botnets calling home, keyloggers and more. It can also automatically deliver security updates via ProxyClient – no software downloads required. To address web content not classified in WebFilter, each WebFilter license includes Dynamic Real-Time Rating (DRTR), a patented technology that rates and categorizes Web content in real time.

WebFilter, powered by the WebPulse collaborative defense, is available both on proxy appliances and a web security SaaS. It enables businesses to protect their users and networks from web-based malware including APTs, spyware, phishing, P2P, streaming traffic, and other attacks.

WebPulse is 100% user driven for relevance creating an unmatched real-time web content rating service, and uses Dynamic Link Analysis (DLA) to check popular websites for attack injections and search engine results for bait pages, both leading to Web threats via dynamic links. WebPulse provides cloud intelligence to ProxySG appliances, and to ProxyClient and K9 Web Protection remote clients. You can also identify and control popular web applications by setting policies through the WebFilter web application policy engine. WebFilter is the next generation of web filtering by combining URL filtering and anti-malware technologies together in a collaborative defense.
