A web site or web site area created for use by a select group. The group is usually the company's employees, clients, and/or select members of the public. An extranet allows for secure exchange of information within the select group - generally about a particular topic. It can also contain forms and applications relevant to the group's needs. For purposes of determining if a website, website area, or application must comply with the Web Site Standard, an "extranet" refers to any online area where access is restricted to a select group of users (by IP address, authentication, VPN, or other technical means). Note that all online material (even extranets and intranets) must comply with the Accessibility Standard.
