Extranets can be used to exchange large volumes of data, share product catalogues, share news with trading partners, collaborate with other companies on joint development efforts, jointly develop and share training programs with other companies, provide or access applications between companies, and much more.
It may sound like a technology for geeks only. But many people use extranets every day without realizing it--to track packaged goods, order products from their suppliers or access customer assistance from other companies.
An extranet is a mechanism based on Internet and Web technology for communicating both privately and selectively with your customers and business partners.
