In essence, an intranet is a business' own private website. It is a confidential business network that uses the same underlying structure and network protocols as the internet, and is protected from unauthorised users by a firewall.

Intranet vs extranet

The main characteristic of an intranet is that it is closed to the public. Extranets, in contrast, are open to the public and typically offer features external users (such as customers, partners and contractors) can access. See what is an extranet.

Intranets are secure and easily accessible via a web browser. As such, they enable businesses to be flexible and control office overheads by allowing employees to work from almost any location, including their home and customer sites - see benefits of intranets.

Examples of intranet

Intranets typically look like a private version of the internet. They use HTTP/HTTPS or other internet protocols to allow sharing of the organisational information and computing resources among employees. You can also use an intranet to facilitate teleconferencing and working in groups.

Certain types of intranets, known as online offices or web offices, merge regular features of intranets with those often found in software such as Microsoft Office. Creating a web office allows you to organise and manage information and share documents and calendars using a familiar web browser function, accessible from anywhere in the world.

Intranet content and features

Intranets can host far more than just company information and policies. The types of content and features commonly found on intranets include:

• administrative - calendars, emergency procedures, meeting room bookings, procedure manuals and membership of internal committees and groups
