Your Website is Already Halfway to Being an Intranet: here's how and why to close the gap with Umbraco

Nearly all companies with over 10,000 employees use an intranet. Fewer than 20% of small businesses do. The gap isn't down to need, it's down to cost, complexity, and the assumption that an intranet means an entirely separate platform but here’s the catch: It doesn't have to. 
For many organisations, the answer is already sitting inside their existing website.

The challenge: Your website is doing too many jobs

We hear a version of this story regularly. A company's website was built for prospects. To tell the brand story, showcase services, convert leads. But over time, colleagues started using it too. To look up a teammate's expertise or to find recent thought leadership. To remind themselves what the company actually offers (you would be surprised how many times we hear this).

Nobody planned for this. And now the site is quietly becoming something it was never designed to be: an internal resource, a de facto knowledge base, a place colleagues go when they can't find information anywhere else. The result, as one client put it, is a "Frankenstein's monster": a public-facing website increasingly tangled up with internal needs it can't properly serve.

A full intranet feels like the logical next step. But a full intranet is often a significant investment one tied up in a new platform, new licences, new training and new ongoing maintenance. For many organisations, the cost simply doesn't stack up against the problem they're trying to solve.

The idea: Same platform, private door

The insight here is simple: a website and an intranet don't have to be two separate things. They just need to serve two different user journeys and with the right architecture, one platform can do both.

We identified that Umbraco's multisite functionality makes it possible to build a lightweight internal hub directly inside an existing template. Colleagues can log in through a dedicated portal, access a separate internal navigation, and interact with content that's completely hidden from the public-facing site but, importantly, it has the same functionality and look and feel of the site. From the outside, nothing changes. From the inside, the organisation gains a functional intranet without touching a second platform.

The technology: Building on what’s already there 

The solution runs entirely within Umbraco, no new infrastructure, no additional CMS to learn, no separate agency to manage. A gated multisite section of the site restricts access to authenticated users only, keeping internal content completely separate from the public website while sharing the same underlying platform.

Role-based permissions control who sees what. Single sign-on integrates with Microsoft 365 or Azure AD so colleagues can use their existing work credentials. Document libraries, member profiles, and internal navigation all sit within the same content management environment editors already know.

Key features: What the platform actually does

• Gated login portal: colleagues access internal content securely, separate from the public site
• Role-based permissions: managers, HR, and general staff each see only and update what's relevant to them
• Internal document libraries: centralised storage for policies, PDFs, and HR documentation
• Reusable content components: the same blocks that power the website work inside the intranet
• Single sign-on: log in once with existing Microsoft 365 or Azure AD credentials
• Member profile management: colleagues can update their own details and preferences
• Separate internal navigation: a distinct menu structure that doesn't interfere with the public site

Efficiency gains: Less searching, less duplication and less overhead

The operational case for this approach goes beyond saving on software licences. When internal information lives in one place, and that place is already part of the platform teams use every day, the hidden costs of fragmentation start to disappear.

• Colleagues stop hunting through email threads, Teams chats, and shared drives for documents that should be easy to find
• Content editors manage both the public website and internal resources in a single CMS: no duplicate training, no context switching
• IT teams avoid the overhead of maintaining a separate intranet platform, its licences, security, and its integrations
• New starters get up to speed faster when internal knowledge is structured, searchable, and accessible from day one
• Knowledge sharing improves naturally: services, expertise, and updates are visible to everyone who needs them

Wider applications: Right-sized for the right organisations

This isn't a replacement for enterprise intranet platforms like Staff Base and it doesn't try to be. It's a right-sized solution for organisations that need more than a shared drive but less than a full digital workplace. This kind of solution is great for growing professional services firms, mid-sized agencies, charities, and membership organisations that already have a well-built Umbraco website and want to get more from it without a significant new investment.

The same approach applies beyond internal communications too. Member portals, client-facing resource hubs, partner extranets or any scenario where a defined group needs access to content that shouldn't be publicly visible would make a worthy candidate for this pattern.

Closing thought: The smartest intranet might be the one you already own

The assumption that internal and external digital tools have to be separate has a cost. In money, in complexity, and in the quiet friction that builds up when colleagues can't find what they need. For organisations already running on Umbraco, the infrastructure for a lightweight intranet is already in place. Sometimes the best technology decision isn't buying something new, it's making better use of what you've already built.
