Co-Managed IT Services in Chicago: Strengthen Your Internal Team Without Replacing It

Co-managed IT means CTI Technology works alongside your internal IT staff instead of replacing them. Your IT person or small team keeps the work that depends on knowing your business, and CTI adds help desk capacity, 24/7 threat monitoring and incident response, patching, backup, Microsoft 365 administration, and IT planning. It is built for Chicago-area organizations with 20 to 250 employees that have one to three internal IT staff.

If you have an internal IT person or a small IT department, you already know the problem: one or two people can’t cover help desk tickets, security monitoring, vendor calls, projects, and long-term planning at the same time. Something always slips, and it’s usually the proactive work that prevents downtime and data loss. Co-managed IT fills that gap without asking you to give up the people who know your systems best.

How Co-Managed IT Works

Co-managed IT is a shared support model with a clear split of responsibilities. Your internal team keeps the work that needs someone close to the business: onsite needs, line-of-business applications, special projects, and day-to-day priorities. CTI takes on the work that is hardest to staff and hardest to do consistently with a small team.

Every arrangement is different. Some clients keep an internal IT person for onsite and specialized work while CTI provides remote help desk support, cybersecurity, monitoring, patching, backup, and planning. Others bring CTI in for specific gaps, such as security operations or Microsoft 365, while their team handles the rest. We agree on the split with you at the start, so nobody has to guess who owns what.

When Co-Managed IT Makes Sense

• Your internal IT person is covering too much, and proactive work keeps getting pushed aside.
• You need around-the-clock security monitoring but can’t staff it internally.
• A cyber insurance application, client audit, or compliance requirement calls for controls and documentation your team doesn’t have time to build.
• You’re growing and need more support before you’re ready to hire another full-time IT employee.
• Your IT staff needs backup coverage during vacations, leave, or unexpected turnover.
• You want senior-level IT planning without the cost of a full-time CIO.

Co-managed IT isn’t only a stopgap. Many organizations keep the arrangement long term because it gives a small internal team depth, security coverage, and a predictable monthly cost.

What Co-Managed IT Costs

CTI publishes its pricing. Our managed IT plans run $200 to $400 per user per month, depending mostly on compliance requirements. A co-managed arrangement is scoped to the work CTI takes on, so it is quoted based on your users, systems, and which responsibilities stay with your internal team. See CTI’s managed IT pricing for details.

Frequently Asked Questions

What is co-managed IT?

Co-managed IT is an arrangement where an outside IT provider works alongside a company’s internal IT staff. The internal team keeps the work that depends on knowing the business, and the provider adds help desk capacity, security monitoring, patching, backup, and planning.

Will co-managed IT replace our internal IT person?

Does CTI provide 24/7 support in a co-managed arrangement?

CTI provides 24/7 threat monitoring and incident response. Help desk support is available Monday through Friday, 8 a.m. to 5 p.m. Central.

How do we decide who handles what?

At the start, CTI and your internal team agree on a clear responsibility split covering help desk, security, patching, backup, Microsoft 365, vendors, and planning, and adjust it as your business changes.

Is co-managed IT a good fit for law firms?
