An '''extranet''' is a controlled private computer network that allows communication with business partners, vendors and suppliers or an authorized set of customers. It extends [[intranet]] to trusted outsiders. It provides access to needed services for authorized parties, without granting access to an organization's entire network.
It can be implemented securely, either with dedicated links or as a VPN.<ref>See {{IETF RFC|4949}}</ref>
