The choice between an internal IT team and an external provider is often presented as all-or-nothing. It is not. A third model — co-managed IT — blends the two, and for many growing businesses it is the best fit. Here is how co-managed and fully outsourced compare, and when each makes sense.
Fully outsourced IT
The provider handles everything — helpdesk, monitoring, security, projects, and strategy. You have no internal IT staff; the provider is your IT department. This suits businesses that want to hand IT off entirely and focus on their core operation. It is the model most people mean by managed IT services.
Co-managed IT
You keep an internal IT person or team, and a provider works alongside them — filling gaps, adding specialist depth, covering after-hours, and taking on the work your internal team does not have time or expertise for. Your team keeps control and context; the provider brings scale and specialism.

When co-managed wins
- You have capable internal IT, but they are stretched thin.
- You need specialist expertise (security, cloud) your team lacks.
- You want after-hours and 24/7 coverage without hiring a night shift.
- You want to keep strategic control internally while outsourcing execution depth.
When fully outsourced wins
Full outsourcing fits when you have no internal IT and do not want to build it, when IT is not core to your business, or when you want a single accountable partner for everything. It is the simplest model — one team, one number to call.
Not sure which fits? It often comes down to the same factors as the broader in-house vs outsourced decision. Talk to us and we will help you map it.
