What is Intranet

An intranet, or internal network, is a locally available web network that is not accessible via the public Internet.  An intranet is a private network that is contained within an enterprise. It may consist of many interlinked local area networks and also use leased lines in the wide area network. The main purpose of an intranet is to share company information and computing resources among employees.

Many companies provide web services that are relevant only to internal employees and not to the public or the company’s customers. Web-enabled applications for internal use can also be created, giving employees access to internal services via a web browser.

The intranet lets only internal employees access these web pages because the information they provide can be confidential and shouldn’t be accessed by the public, especially by rival companies.

The web servers that host intranet services are located on the private internal LAN in the overall security zone model to prevent access from the public zone.
