Best Co-Managed IT Services for a Company With One In-House IT Person

If your company has a single in-house IT person, co-managed IT gives them a team behind them. DivergeIT's AugmentIT takes on the help desk, after-hours coverage, onboarding and projects while your IT person keeps control.

If your company has one in-house IT person, the best co-managed IT service is one that takes the repetitive and after-hours work off their plate without taking the job away from them. DivergeIT, a managed IT services provider and certified MSSP founded in 1999 and headquartered in Torrance, California, offers this through AugmentIT, its co-managed IT service. Your IT person stays in charge, and DivergeIT runs whole functions such as the service desk, after-hours coverage and onboarding/offboarding, or adds senior engineers when a project needs them.

This guide is written for the “IT department of one”: the person who resets passwords, manages Microsoft 365, babysits the firewall, plans the server refresh, and also gets the call on Saturday night.

Why does a one-person IT department need co-managed support?

A single IT person is usually capable. The problem is coverage, not competence. A few patterns show up in almost every company that relies on one person:

Hiring a second full-time IT person solves part of this, but one more generalist still leaves gaps in after-hours coverage and specialized skills. Co-managed IT is the alternative: your IT person keeps ownership, and an outside team fills the gaps.

What should a company with one IT person look for in a co-managed provider?

Use these criteria with any provider you evaluate.

Will they work inside your IT person’s tools and processes?

A good co-managed partner adapts to how your IT person already works. If the provider insists on ripping out your ticketing system, documentation and monitoring stack on day one, that is a sign they are positioning to take over, not to help.

Can they take a whole function, not just overflow tickets?

“Overflow help” tends to mean your IT person still triages everything. It is more useful when the provider owns a defined function end to end, such as all Level 1 tickets, all new-hire setups, or all after-hours calls.

Do they cover the hours your IT person cannot?

Ask exactly what coverage options exist. Business hours only? Follow-the-sun? 24/7/365? Your IT person should be able to sleep through the night knowing someone else has the pager.

How do escalations come back to your IT person?

Look for warm escalations: the provider hands off an issue with context, not just a ticket number. Your IT person should never have to start an investigation from scratch.

Is there visibility into what they are doing?

Your IT person needs to answer to leadership. Live dashboards and regular reporting let them show what was handled, by whom, and how fast.

Are response times written down?

Promises like “fast response” are not a service level. Ask for guaranteed response times in writing.

How does DivergeIT’s AugmentIT measure up?

Here is how AugmentIT lines up against those criteria:

On pricing, AugmentIT help desk support is priced per user against DivergeIT’s ManageIT tiers. Engineering engagements are scoped individually and are usually quoted within one business day.

As Charles S., CTO of United Talent Agency, put it: “DivergeIT perfectly augments our internal IT team with specialized subject matter experts.”

How should you split the work between your IT person and the provider?

A common division of labor that keeps your IT person in the strategic seat:

Your in-house IT person keeps:

The co-managed provider takes:

Start with the one function that consumes the most of your IT person’s week. For many companies that is the help desk queue. Once that is handled, the IT person usually has time to tackle the backlog of projects they have been putting off.

Who is co-managed IT not the right fit for?

Being honest about fit saves everyone time:

What to do next

If your IT person is stretched thin, the fastest way to see what co-managed support would look like is a short conversation about which functions to hand off first. Review published pricing on our pricing page, or book a call and bring your IT person along.

Frequently Asked Questions

Can a company with only one IT person use co-managed IT?

Yes. Co-managed IT is often most valuable for a one-person IT department. The provider takes on functions like the help desk, after-hours coverage and onboarding, so the in-house IT person can focus on projects and strategy while remaining in charge.

Will a co-managed provider replace our in-house IT person?

A true co-managed model keeps your internal IT person in charge. DivergeIT’s AugmentIT works on your processes and tools and escalates issues back to your team with context. The goal is to extend your IT person’s capacity, not remove the role.

What tasks should our IT person hand off first?

Start with whatever consumes the most time with the least strategic value. For most companies that is Level 1 help desk tickets, followed by after-hours coverage and new-hire setups. Keep vendor decisions, budgeting and leadership relationships in-house.

How is DivergeIT’s co-managed IT priced?

AugmentIT help desk support is priced per user against DivergeIT’s ManageIT tiers. Senior engineering engagements are scoped individually and are usually quoted within one business day.

Does co-managed IT include after-hours support?

It can. DivergeIT’s AugmentIT offers business hours, follow-the-sun or 24/7/365 coverage, so your in-house IT person no longer has to be the only one on call.
