Co-managed IT services in Tulsa — for the business that has an IT person and needs an IT department
Your IT person is good. They are also the only phone that rings, the only one who knows how the server is set up, and the reason nobody wants them to take a vacation. You should not have to choose between overloading one person and outsourcing the whole thing.

One person cannot be a department — and should not have to be
A business of 30 to 100 people usually has more IT than one person can carry and less than justifies three. So the one person carries it: first-line support, servers, network, security, Microsoft 365, backups, vendors, projects, and the strategy nobody has time to think about. It works until they are sick, on vacation, or hiring elsewhere — and it never leaves room for the work that would actually move the business.
Co-managed IT is the middle option. NSN Management becomes the rest of the department: the desk that answers so your IT lead can think, the second line to escalate to, the specialists for the things a generalist rarely owns, and the coverage that makes a week off just a week off. Your IT person keeps the parts of the job that need someone in the building who knows the business. The split is written down, so nothing lands in the gap.
You might need co-managed IT if
- Your IT person’s projects keep sliding behind password resets and printer calls
- Only one person knows how the network, the server, or the tenant is set up
- Vacations get planned around IT, or nobody has covered the desk when your IT lead was out
- Security, Microsoft 365 governance, or backup testing is “on the list” and has been for a year
- You are weighing a second IT hire and are not sure the work is really a full role
- Your IT person is great with the business’s applications and would rather not be the security team too
How the split usually works
There is no single co-managed model. These are the three shapes we see most often — and every engagement is written down as its own version.
Your team leads, we cover the desk
The most common shape. Your IT person owns the strategy, the line-of-business applications, and the relationships; NSN Management takes first-line support so they stop being interrupted forty times a day, and steps in for escalations, after-hours, and time off.
We run the platform, your team runs the business
NSN Management owns infrastructure, security, Microsoft 365, backup, monitoring, and patching; your team owns the applications only your business understands — the ERP, the practice-management system, the custom software — and the people side.
Escalation and specialties only
Your team handles day to day. NSN Management is second and third line — the security stack, the tenant, the servers, the network — plus projects and the vacation and turnover gaps. Lightest touch, still with the split written down.
What you get
The same platform, security stack, and process as our fully managed clients — with the responsibilities divided to fit the team you already have.
- A written division of responsibilities — who owns the help desk, escalations, servers, network, security, Microsoft 365, backup, vendors, and projects — agreed before day one and revisited as your team changes
- Help desk coverage at whatever level fits: first-line for your people so your IT staff can work on projects, overflow only, or escalation and second-line behind your own first line
- Backup for your team’s vacations, sick days, and turnover — the environment is documented and known to us, so a week without your IT person is not a week without IT
- Monitoring, patching, and documentation on the same platform we run for fully managed clients, with your team given visibility into tickets, alerts, and the documentation
- The specialties a one- or two-person team rarely has time to own: layered security and managed detection and response, Microsoft 365 and Entra ID governance, tested backup and recovery, business phones, cloud migration, and AI and Copilot readiness
- Project capacity — server and network refreshes, office moves, migrations, acquisitions — scoped and delivered alongside your team, not around them
- A vCIO seat at the table: budgeting, roadmap, and vendor decisions with your IT lead, so strategy is not one person’s spare time
- Monthly reporting your IT lead and your owner can both read, and regular meetings so nobody is guessing who owns what
Built for businesses of roughly 30 to 100 people with one IT person or a two- or three-person team — including firms whose IT lead is strongest on the line-of-business applications and would rather hand off infrastructure and security, organizations that outgrew fully managed IT and hired internally but want to keep the depth, multi-site or growing businesses where one person cannot be everywhere, and owners who want a real second opinion on IT spend and strategy.
What a one-person department exposes you to
- Everything stops — or nobody answers — the week your IT person is out
- Knowledge that lives in one head, and leaves with it
- Security, backup testing, and Microsoft 365 governance that never make it off the list
- Projects that slide for a year because the desk never stops ringing
- A second IT hire made — or not made — on guesswork
How it starts
A low-pressure way to find out what a shared IT department would look like for your business — with your IT lead in the room.
Book a Discovery Call
A focused conversation — ideally with your IT person — about what they carry today, what keeps sliding, and where coverage is thin. No obligation, no hard sell.
Agree the split
We document your environment, propose a division of responsibilities, and put it in writing with your team: who owns what, how escalation works, and how coverage runs when someone is out.
Onboard alongside your team
Monitoring, documentation, and the security baseline go in; your people learn where to call; your IT lead gets their projects back — and the split is revisited as the business changes.
What changes for you
Your IT lead gets their job back — first-line support handled, escalation available, and the projects they were hired for actually moving. Coverage stops depending on one person: a documented environment, shared tools, and a desk that answers whether or not your IT person is in. And you get depth without the headcount — security, Microsoft 365, backup, phones, cloud, and AI readiness from specialists, without hiring five people.
All of it from a team your IT person will actually want to work with. NSN Management is a Tulsa-owned managed IT provider that has worked alongside internal IT people since 2012 — as the department behind them, not a replacement for them. Co-managed clients get the same platform, security stack, and process as our fully managed clients, the same measured responsiveness (9-minute median first response, Feb–Jul 2026 — a measurement, not a promise; your standards are agreed up front and reported monthly), a truly local team that can be in your building, and regular meetings where your IT lead and your owner both see the same report.
Co-managed IT is the sibling of managed IT services; it draws on cybersecurity, Microsoft 365 management, and backup and disaster recovery for the specialties most internal teams hand off first. Curious how the two models compare? Start with what managed IT services are, or book a Discovery Call.

Your co-managed IT questions, answered
What is co-managed IT?
Co-managed IT is a managed IT service shared between an internal IT person or team and an outside provider, with the responsibilities divided and written down. Instead of replacing your IT staff, NSN Management works alongside them — typically covering the help desk, after-hours and vacation gaps, security, Microsoft 365, backup, and projects — so a small internal team gets the depth, tools, and coverage of a larger department without hiring one.
How is co-managed IT different from fully managed IT?
In fully managed IT, NSN Management is the IT department. In co-managed IT, you have one, and we extend it. The tools, the monitoring, the security stack, and the process are the same; what changes is who owns which responsibilities, which is agreed and documented at the start. Businesses move between the two as they grow — a company that hires its first IT person often shifts from fully managed to co-managed without changing providers.
Who owns what in a co-managed arrangement?
Whatever you and we agree, in writing. The usual split has NSN Management on the help desk, monitoring, patching, security, Microsoft 365, backup, and after-hours coverage, and your internal team on strategy, the line-of-business applications only your business understands, on-site hands, and the relationships with your people. But the split can run the other way, and it can change — the point is that both sides know, and nothing falls in the gap.
Will co-managed IT replace our internal IT person?
No. Co-managed IT exists so you do not have to choose between an overloaded one-person department and an outsourced one. Most internal IT people we work with are relieved: they stop being the only phone that rings, they get colleagues to escalate to, and they get time for the projects they were hired to do. If a business ever decides to change its structure, that is its call, not something the arrangement is designed to cause.
Does our IT person get access to your tools and documentation?
Yes. Your team gets visibility into the monitoring, ticketing, and documentation for your environment, and we work in shared systems rather than parallel ones. Documentation of your environment lives where both teams can reach it — which is also what makes covering a vacation or a departure straightforward.
How does after-hours and vacation coverage work?
It is written into the agreement. Because we already know and document your environment, your IT person can be off — planned or not — and your people still have somewhere to call. Coverage is defined as part of the split rather than assumed, so everyone knows what is handled and how.
How much does co-managed IT cost?
Co-managed IT is priced per person per month like fully managed IT, and it generally sits below the fully managed range because your team carries part of the load — how far below depends on the split. Projects are scoped separately. We quote after a short look at your environment and a conversation about who will own what; our managed IT cost guide covers the Tulsa market ranges for the fully managed service so you have a reference point.
Can co-managed IT start with one thing, like security or Microsoft 365?
Yes. Many co-managed relationships start with a single specialty the internal team wanted off their plate — managed detection and response, Microsoft 365 and Entra ID, backup and disaster recovery, or a project — and grow from there. Starting narrow is a good way for both teams to learn how the other works.
Do you provide co-managed IT outside Tulsa?
Yes. NSN Management works with internal IT teams across the Tulsa metro, including Broken Arrow, Jenks, Bixby, Sand Springs, Sapulpa, and Owasso — remotely for most of the work, and on-site when your team needs another pair of hands in the building.
