dolphian Web content filtering and compliance for OEM
printable version

Dolphian's Web content filtering solution offers unparalleled efficiency, performance and flexibility, enabling high efficiency Web access filtering based on content analysis. Web pages are not merely authorized or denied based on their URL classification, but actually analyzed and classified based on what is in them.



Corporations and Network Operators alike require filtering Internet access.
Corporate customers and retail subscribers alike have a need for filters that can efficiently guarantee that they abide by the law, that their computers do not receive malware and that some categories of users are protected against content-borne threats.

Whether corporate customers want to manage Web usage control, or parents want to subscribe to parental controls services, security and network appliances vendors have an opportunity to reduce bandwith usage, increase customer satisfaction and improve revenue and margin.


Filtering Web based on URL databases is not optimal for OEM.


OEM vendors require efficiency and quality. Downloading and upgrading URL databases is both costly in terms of resources and challenging in terms of business model.

Additionally, it Iis far from efficient as 2 major trends have definitely altered the nature of Web filtering:


  • The most interesting content on the Internet is now more and more found on contribution systems, such as Weblogs (blogs) or forums. When researchers or children need information, they know they will probably find the most relevant and up to date contents on sites that cannot be identified by their URL. This content is fresh because it does not have one author and one publisher but many. Therefore, no URL categorization database can properly classify it.
  • On the other side, adult Web sites, hackers repositories, digital rights hackers, know how to hide their addresses, change them on a regular basis, or make sure they cannot be identified properly.


At Dolphian we can analyze Web contents fast enough to enforce real policies
Dolphian's Web Content Analyzer (WCA) is a one of a kind HTTP session content analyzer, fast enough to execute pattern matching on a Web page on-the-fly without altering the user experience.

Based on Dolphian's proven pattern matching engine, already deployed on over 5,000 network appliances and protecting hundreds of organizations of all sizes, WCA takes an average of 3 milliseconds to make a classification decision on a Web page based on the content. This means accurate analysis even when page content changes, or when page URL address changes.

Additionally, Dolphian maintains URL and IP addresses knowledge bases to supplement WCA when content analysis is not the only interesting technique.

Fully manageable and lightning fast, Dolphian WCA classifies HTTP session content (Web pages, but also embedded protocols) and connects to infrastructure applications via industry standard i-CAP protocol.

Dolphian WCA natively supports personalized filtering as content and context information are analyzed at once.


Deployment is easy and riskless.

Dolphian WCA is deployed as an add-on feature on existing or new proxy servers provided they are compatible with industry standards, which includes carrier-grade commercial products as well as open-source servers.

Dolphian WCA can also be deployed on independent interception servers specifically equipped to avoid SPOF* with load-balanced servers fitted with by-pass network cards.

Log management is handled by the existing log analysis or event analysis equipment or ad'hoc solutions.


With Dolphian WCA, add value to your solutions, and retain the revenue.
