Definition
An intranet is a private website or network that only an organisation's employees can access, usually after signing in. It holds internal news, policies, documents, staff directories and links to tools such as HR self-service, so people can find what they need in one place.
How an intranet system works
An intranet system uses the same technology as the public web, such as browsers, web servers and standard protocols, but access is restricted to people inside the organisation. Traditionally that meant being on the office network or connected through a VPN. Most modern intranets are cloud-hosted and use single sign-on, so employees log in with their work account from any device.
Behind the pages sits a content management system that lets HR, IT and internal communications teams publish updates, along with a search engine, permissions that control who sees what, and connections to other workplace tools.
Internal vacancies posted on the intranet still need a fair first round, and springhire's candidate screening platform scores internal and external applicants against the same criteria.
Intranet vs internet vs extranet
The internet is the public network anyone can reach. An intranet is a private space for employees only. An extranet opens part of that private space to selected outsiders, such as suppliers, franchisees or clients, who get their own logins and see only what is shared with them.
When people in IT say intranet, they sometimes mean the internal network itself rather than the employee portal. In HR and internal communications, the word almost always means the portal.
What a good intranet includes
The useful core is small: a company news feed, a searchable library of policies and handbooks, an employee directory with roles and contact details, and quick links to everyday tools such as leave requests, payslips, expense claims and the IT help desk. Many organisations also post internal vacancies there, which supports internal mobility.
Onboarding is often where an intranet proves its worth. New starters can find the handbook, team pages and first-week checklists without asking the same questions their predecessors asked.
Choosing intranet software
Organisations can build an intranet on a collaboration platform they already use, buy a dedicated intranet product, or, less often, develop their own. The choice usually comes down to how much structure and branding you need, how well it connects to your existing sign-in and document tools, and who will maintain it day to day.
Whichever route you take, plan the structure around tasks employees actually do, such as booking leave or finding a policy, rather than around the organisation chart.
Why intranets fail
Most intranets fail through neglect rather than technology. Pages go out of date, search returns an old version of a policy, and nobody owns the content. Give each section a named owner and a review date, archive what is stale, and test search with the questions employees actually ask.
Adoption also suffers when the intranet duplicates chat tools. Decide what belongs where: quick conversation in chat, lasting reference material on the intranet.
Frequently asked questions
An intranet is used to share company news, store policies and documents, help employees find colleagues, and give quick access to internal tools such as leave booking or payslips. It acts as a single starting point for work information, which is especially useful for onboarding and for teams spread across sites.
No. The internet is a public network open to anyone. An intranet uses the same web technology but is private, so only signed-in employees can reach it. An extranet sits between the two, giving selected outside partners access to a limited part of the private system.
In IT, an intranet can mean the organisation's private internal network, meaning the servers and connections only staff devices can reach, as well as the employee website that runs on it. In everyday business use, intranet usually refers to that internal website or portal rather than the network underneath.
