O que (quem) é extranet$501371$ - definição

An extranet is a controlled private network that allows access to partners, vendors and suppliers or an authorized set of customers – normally to a subset of the information accessible from an organization's intranet. An extranet is similar to a DMZ in that it provides access to needed services for authorized parties, without granting access to an organization's entire network.

<World-Wide Web> The extension of a company's intranet out onto the Internet, e.g. to allow selected customers, suppliers and mobile workers to access the company's private data and applications via the World-Wide Web. This is in contrast to, and usually in addition to, the company's public website which is accessible to everyone. The difference can be somewhat blurred but generally an extranet implies real-time access through a firewall of some kind. Such facilities require very careful attention to security but are becoming an increasingly important means of delivering services and communicating efficiently.
