Intranet: Definition and Features

- An intranet is a closed network specific to one organization: only authorized people can reach it, unlike the internet, and it is not open to customers or partners, unlike the extranet.
- Born in the 90s as a single page of internal information, it has become in thirty years a cloud workspace, reachable from anywhere and from mobile.
- Its main features: internal documents, news, surveys, directory, org chart, knowledge base, shared calendar and search engine. Its secondary features: email, chat, videoconferencing, project management, HR area.
- According to the Arctus 2023 study (377 companies), one intranet in two offers a collaborative workspace, 46% electronic document management, 40% co-editing and 37% instant messaging.
- It is deployed first to keep internal information flowing (the primary digital challenge for 69% of the companies surveyed), then to capture knowledge and improve operational efficiency (59% each).
- The installed base has grown younger: two companies out of three run an intranet that is three years old or less, against 20% in 2009.
If you work in a large company or a large group, you are probably familiar with the term intranet. Since the 90s, the intranet has earned a central place in organizations. It has of course been modernized along the way, following trends and technological innovations.
It has become a social and collaborative tool. According to the 2023 study by the Observatory of the Intranet and Digital Communication, run by Arctus among 377 companies, one intranet in two offers a collaborative workspace, 46% include electronic document management, 40% allow co-editing and 37% have instant messaging.

1) Definition
The early intranet
An intranet is a local network specific to one organization (a company, a university, an institution) that lets employees access internal information and communicate with each other. It works like a website: it requires a web server and the associated protocols. Unlike the internet, which is open to everyone, an intranet stays closed: only the people the organization authorizes can reach it. It should not be confused with the extranet either, which is intended for external use: a network made available to customers, suppliers and partners.
Initially, the intranet was only accessible from workstations connected to the local network. To connect, users needed a login and a password. In its early days, it served internal communication, with a simplified interface, often a single page gathering a lot of information.
Over the years, this internal network has evolved, integrating more and more features and offering interfaces that are easier and more pleasant to use.
The intranet today
In thirty years of existence, the intranet has been transformed, enriched and modernized. It has gradually incorporated technologies (business chat, videoconferencing, news feeds) until it became a real workspace.
Companies now use the "cloud" intranet, which removes the limits of on-premise servers by letting authorized people connect from anywhere. Today’s intranet often comes with a search engine, a calendar, a mobile application and a whole set of tools that keep users effective even when they are on the go.
The installed base has also grown younger: according to the same Arctus study, two companies out of three run an intranet that is three years old or less, whereas in 2009 only 20% of intranets were under three years old.

2) Intranet features
An intranet makes the documents and information needed to run the company available to employees, while reducing the risk of data leaking outside. It centralizes information and provides permanent access to it.
As mentioned above, it is increasingly common, and this is a natural extension of the initial uses, to see collaborative work features integrated into intranets.
Main features:
- Access to internal documents (procedures, forms)
- Sharing of important internal news (replacing the internal newsletter)
- Internal surveys
- Employee directory
- Organizational chart
- Knowledge bases
- Shared calendar (gathering important internal events)
- Search engine to find documents and files easily
Secondary features:
- Chat
- Videoconferencing and audioconferencing
- Project management
- HR area (to book leave, submit expense reports)

3) Why set up an intranet?
An intranet is not deployed for the technology, but to solve specific organizational problems. The Arctus 2023 study sets out the priorities companies address with their internal digital platform.
- Keeping internal information flowing. Internal communication is seen as the primary digital challenge by 69% of the companies surveyed.
- Capturing and passing on knowledge. This comes next, cited by 59% of respondents, at the same level as operational efficiency.
- Building social bonds between employees. 59% of respondents see it as an opportunity of internal digital, ahead of engaging and retaining talent (36%) and supporting remote work (34%).
- Keeping sensitive documents inside. A closed space with access rights avoids files circulating as attachments outside the organization.

4) What comes after the intranet?
As digital habits changed, the intranet went through major shifts and now brings many services to organizations and their employees. With the rise of the digital workplace, it will once again have to redefine its role and its contribution to the company community. Many software publishers have already repositioned themselves, starting with Talkspirit.
