Blue Coat Delivers Inline Malware Protection For Web-Based Content

Blue Coat Systems has made an effort to advance inline malware detection of Web content with a new technology that provides businesses with granular control over open-ended Web-based applications, such as Internet radio or online broadcasts. Defer scan technology enables Blue Coat ProxySG appliances to intelligently defer the processing of these type of applications to ensure they do not impede the performance of business-critical applications on the network.

“The growing adoption of Web-based media applications forces businesses to reconsider how they protect their networks, particularly at the Internet gateway where response times need to be instantaneous,” said Bethany Mayer, SVP of worldwide marketing and corporate development at Blue Coat Systems. “Blue Coat ProxySG and ProxyAV appliances enable network administrators to strike an optimal balance between network performance and Web security by utilising intelligent control to ensure all types of Web-based content are analysed without impacting network performance.”

Blue Coat ProxySG appliances work in conjunction with Blue Coat ProxyAV appliances to provide the intelligence and control required to analyse all incoming Web content without compromising the performance of business applications managed by the Internet gateway. With the Blue Coat defer scan technology, ProxySG appliances process open-ended Web-based applications, such as streaming baseball games or radio, that maintain persistent connections until closed, freeing processing capacity on the ProxyAV appliances for critical malware detection tasks. By processing the open-ended Web stream on ProxySG appliances instead of immediately sending it to ProxyAV appliances, Blue Coat allows administrators to optimise network performance.

Removing Internet radio and other open-ended Web-based applications from the anti-malware processing queue ensures scalable malware detection, enabling network administrators to provide an additional layer of security. Legacy products that do not utilise defer scan technology force administrators to make trade-offs: either block access to Web media content and related websites or skip the analysis of those sites. While blocking Web content frustrates users that require access to Web-media sites, not analysing this Web content and the sites that host it opens a door for malware infiltration. Blue Coat’s defer scan technology provides intelligent analysis to analyse all Web content accessed by users while maintaining performance at the Web gateway.
