Managed vs Co-Managed vs In-House IT
An honest comparison of the three ways to run IT for a business or public body: a fully managed provider, a co-managed arrangement alongside your own staff, and an entirely in-house team, and when each one is the right choice.
Overview
There is no best model. There is a best model for the team you have.
Fully managed IT means a provider runs the whole function: help desk, devices, security, backups, vendors and planning, for a monthly fee. It suits organizations with no IT staff, or with IT staff they would rather point at other work. The trade-off is that the people who know your systems best work for someone else, which is why the documentation, the accounts and the decisions must stay in your hands.
In-house IT means you hire, manage and keep the team yourself. You get people who know the business closely and sit in the building. The costs are less visible: salaries for every specialty you need, the tools and licenses a provider would otherwise bring, cover for holidays and departures, and the difficulty of hiring a security specialist who stays. For a large organization with the budget and the management attention, it can be the right answer.
Co-managed IT is the middle path. Your IT staff stay in charge of the environment and the business relationships, and a provider supplies the platform, after-hours monitoring, security operations, overflow and specialists, with the split written down. It is often where organizations with one to a handful of IT people end up, because it removes the single point of failure without replacing anyone.
We offer the first two and work alongside the third, so we have no reason to push one. The comparison below is how we explain the difference to buyers.
Capabilities
What's included
- Who answers the help deskFully managed: our technicians. Co-managed: your team first, with our help desk taking overflow and whatever you hand over. In-house: your team, and nobody else when they are busy or away.
- Coverage outside business hoursFully managed and co-managed: monitoring and security operations around the clock from the provider. In-house: only if you staff an on-call rotation, which a small internal team struggles to sustain.
- Security specialistsFully managed and co-managed: detection and response analysts, vulnerability management and compliance work from people who do only that. In-house: the skills your team has, or a separate security vendor to manage.
- Cost structureFully managed: a flat monthly fee per device. Co-managed: a lower fee for a narrower scope, plus your staff's salaries. In-house: salaries, benefits, training, recruiting and every tool and license, paid by you.
- Control and knowledgeIn-house: everything sits with your people. Co-managed: shared, with your team in charge and documentation in a common system. Fully managed: the provider does the work, so insist that accounts and documentation are yours.
- Continuity when someone leavesIn-house: knowledge can leave with the person. Co-managed: the provider and the shared documentation cover the gap. Fully managed: the provider's bench absorbs staff changes, which is part of what you pay for.
- Best fitFully managed: no IT staff, or a team you want focused elsewhere. Co-managed: one to a handful of stretched IT staff. In-house: a large team with security specialists, on-call cover and the budget to keep them.
How It Works
How we fit each model
Fully managed and co-managed clients run on the same management platform, the same documentation system and the same security services; the difference is who does which work, and that is written into the agreement. For organizations keeping IT entirely in-house, we can still take on a defined project or a specialist service, such as managed detection and response or a compliance readiness program, as a standalone engagement.

Common Questions
Questions we get asked
Is co-managed or fully managed IT cheaper?
Co-managed usually has the lower monthly fee because your staff do part of the work, but your total cost includes their salaries. Fully managed has a higher fee and fewer internal salaries. The honest comparison is total cost for the coverage you need: count the people, the tools, the after-hours cover and the security specialists each option provides, not only the invoice. We will walk through that comparison with your own numbers.
Is in-house IT ever the better choice?
Yes. A large organization with enough staff to cover every specialty, hold an on-call rotation and absorb departures can run IT well in-house, and it gains people who know the business deeply. Organizations with unusual systems, such as production lines or specialist clinical equipment, also benefit from internal expertise. Even then, many bring in a provider for specific layers such as 24/7 security monitoring.
Will co-managed IT make our IT staff feel replaced?
It should do the opposite. The arrangement exists because one or two people cannot be the help desk, the security team and the project lead at once. They stay in charge and decide what we take on; we take the after-hours alerts, the overflow and the specialist work. Most internal IT leads find the job becomes more sustainable, because they are no longer the single point of failure.
Can we switch from one model to another later?
Yes, and organizations often do as they grow or change. A company that starts fully managed may hire an IT manager and move to co-managed; one that loses its IT lead may move the other way while it recruits. Because the documentation and the platform are shared, the change is a revision to the agreement rather than a new provider and a fresh start.
How do we decide which model fits us?
Start with three questions. Do you have IT staff, and are they stretched? Who handles a security alert at 2 a.m. today? What would happen if your most knowledgeable IT person left next month? The answers usually point to one model. Our free IT assessment also documents your current environment and its gaps, which makes the choice clearer whichever model you pick.
What should be in writing whichever model we choose?
Who owns each responsibility, including after-hours response, security alerts, backups, vendor management and projects; which devices and systems are covered; how changes are approved; what reporting you receive; and the exit terms, including that accounts, documentation and admin access stay yours. With an entirely in-house team, the same list belongs in job descriptions and an on-call policy.
