Blue Coat's WebFilter uses a dynamic database which is superior to competing static databases. Traditional filtering requires the customer to download a static list of URLs. This list becomes outdated as soon as it is downloaded. New websites are created continuously and dynamic sites change constantly, therefore if the customer does not have access to continuous and instant updates, the static database will be insufficient on reception. WebFilter is capable of handling dynamic content due to its proprietary WebPulse community which continously updates the database with signatures for new URLs, content and malware. Furthermore, traditional content control filters per destination IP and hostname are, not being able to distinguish different content within the same host. WebFilter from Blue Coat is much more granular and filters per domain, host directories and files.
Dynamic Real-Time Rating (DRTR) is a proprietary technology, which is able to categorize web pages instantly. Any new website that isn't already in Blue Coat's database is analyzed in real-time.
If the DRTR mechanism is able to rate the content with a high level of confidence, it is automatically pushed to the master database to incorporate the new content. Blue Coats service points, running the WebFilter service, are updated instantly to deliver the new updates to all customers. If the DRTR service isn't able to categorize the content automatically in one of the existing categories, the content is manually reviewed by humans, who are able to categorize it properly. This system assures that Blue Coat's database is the most accurate and relevant database in the industry. While competitors may brag about the size of their database, they conceal the fact, that most of this data may be outdated or irrelevant, which is not going to deliver effective results to customers.
End-users instantly benefit from Blue Coat's growing database instantly. With DRTR and Blue Coat's manual rating system, end-users will benefit from the activity of all of Blue Coat's customers. End-users that access unrated URLs will automatically direct those URLs through WebFilter to Blue Coat's service points, where they will become rated, thus other customers that access those sites later, will be served the rating instantly and accurately from the database. The database will also grow bigger and more accurate as more and more customers use the system. Customers all over the world are using WebFilter and thus, taking part of building the largest, most accurate database available in the industry.
Reporting allows customers to receive "Violation Reporting", that will provide company-wide to user-specific reports on the sites that end-users tried to access and were blocked. This is a feature of the system and will require no additional hardware. Reports are web-based and real-time. They can be viewed by administrators anytime and from any location.
