An external Web site for an organization; usually secured so that only authorized users can gain access to it.

An intranet with extended access, generally behind a firewall. For example, a company may give the public access to certain parts of its intranet and restrict access to others. This can be done by using firewall programs or routers, via a proxy, or by specialized software.

An intranet that has been extended to include access to or from selected external organizations such as customers or suppliers, but not the general public.
