NetSpective WebFilter

NetSpective WebFilter lets corporate managers prevent employees from accessing URLs that contain content the company finds objectionable. Decisions on objectionable content are determined on the basis of legal or ethical concerns, employee productivity, network security, or any other issue. NetSpective WebFilter's robust categorization engine includes millions of potentially objectionable sites in more than 60 URL categories, from pornography to finance/investing; file sharing to online chat.

Comprehensive Web Filtering Methods

Any webfilter is only as good as the way in which URL categorization is performed. Many competing solutions utilize one or two methods of categorization. NetSpective WebFilter maximizes its accuracy by relying on all known categorization techniques, including:

• Manual review - A staff of professional Web surfers scans sites for objectionable content and categorizes URLs manually;
• Licensed contextual URL filtering engine - NetSpective WebFilter relies on commercially available artificial intelligence engine used by leading Web service providers in their parental controls. Sites and keywords are evaluated in the context of surrounding content;
• Internally developed neural net analysis programs - Verso's own proprietary neural net analysis engine automatically determines the appropriate category for URLs based on keyword analysis;
• ICRA Ratings - NetSpective WebFilter recognizes content labels generated by the Internet Content Rating Association which Web developers often put on their sites.

Continual updates to Web Filtering database

For ongoing URL updates, NetSpective relies on it's Adaptive Filtering; a patent-pending technology that provides comprehensive and accurate content review for all sites surfed by your organization. Conventional URL filters are built around keyword or list-based filtering technologies that can cause irritating over-blocks or completely ignore large numbers of problem web sites. In contrast, Adaptive Filtering categorization is driven by actual web usage at NetSpective customer locations. When a user surfs to a site, the URL is immediately compared against NetSpective WebFilter's embedded URL database. Unknown URLs are forwarded to the NetSpective Adaptive Filtering Lab, where they receive both automated and human review. Newly categorized sites are then redistributed to the entire NetSpective user community. This "closed-loop" approach maximizes your filtering accuracy, ensuring that even the most obscure sites receive full content review.
