Managed IT means an outside IT provider assumes responsibility for most or all of a company's day-to-day technology needs. Co-managed IT combines an existing internal IT team with an outside managed service provider that supplies additional people, tools, expertise, or coverage.

For businesses deciding between the two models, the right choice usually depends on one question:

Do you need someone to be your IT department, or do you need someone to strengthen the IT department you already have?

Here are nine important differences.

Managed IT vs. Co-Managed IT at a Glance

Business Need	Managed IT	Co-Managed IT
No internal IT department	Excellent fit	Usually unnecessary
Existing IT manager or team	Possible	Excellent fit
Day-to-day help desk	MSP handles it	Shared or MSP-supported
Cybersecurity	MSP manages it	Shared responsibility
Microsoft 365	MSP manages it	Internal + MSP
Large IT projects	MSP handles or coordinates	MSP supplements internal team
Vacation coverage	Built into MSP team	Common use case
Strategic IT planning	MSP provides guidance	Collaborative
Staffing shortages	Replaces need for some hires	Extends existing staff

1. Managed IT Can Function as Your Entire IT Department

The biggest difference between managed and co-managed IT is ownership. With managed IT, the outside provider usually becomes the primary IT department. That can include responsibility for:

Help desk support
Employee onboarding and offboarding
Microsoft 365
Cybersecurity
Computers
Servers
Networks
Backups
Vendors
IT documentation
Technology planning

Managed IT is especially useful for organizations that have outgrown relying on an office manager, technically inclined employee, or break/fix IT company but are not ready to build a full internal IT department.

2. Co-Managed IT Works Beside Your Internal IT Team

Co-managed IT is designed for businesses that already have IT employees. Instead of replacing the internal team, the managed service provider acts as an extension of it. For example, an internal IT manager may continue managing:

Business applications
Employee relationships
Strategic priorities
Technology decisions

The MSP may provide:

Help desk support
Cybersecurity
Microsoft 365 expertise
Network monitoring
Backup
Project engineering
After-hours coverage

The exact division of responsibilities can be customized.

3. Managed IT Centralizes Day-to-Day Support

In a managed IT model, employees typically contact the managed service provider whenever they need technical help. The MSP becomes the help desk for issues such as:

Password resets
Computer problems
Microsoft 365 questions
Printer problems
Network connectivity
Software issues
New computer setup

This gives businesses a consistent support process without needing to staff their own help desk.

4. Co-Managed IT Can Take Pressure Off an Overloaded Help Desk

Internal IT teams often spend a large percentage of their time responding to repetitive support tickets. That creates a problem. Highly skilled IT employees may spend their days resetting passwords and troubleshooting printers instead of working on:

Security improvements
Infrastructure upgrades
Cloud projects
Automation
Business systems
Strategic planning

A co-managed IT provider can take over all or part of the help desk function. For example, the MSP may handle Tier 1 support while the internal IT team handles more complex or company-specific issues.

5. Managed IT Provides Access to a Team Instead of One Person

Many small businesses reach a point where they realize they need dedicated IT expertise. The first instinct may be to hire one IT employee. The challenge is that modern IT requires expertise across many areas:

Networking
Cybersecurity
Microsoft 365
Cloud services
Backup
Servers
Endpoint management
Compliance
Business applications

It is difficult for one person to be an expert in all of them. Managed IT gives businesses access to multiple technical resources without building an entire department internally.

6. Co-Managed IT Helps Fill Skill Gaps

The same challenge exists inside larger IT departments. A three-person IT team may be excellent at supporting the company's applications and employees but have limited experience with:

Microsoft Entra
Conditional Access
Cloud migrations
Advanced cybersecurity
Network redesign
Disaster recovery
Major Microsoft 365 projects

Hiring a full-time specialist for each discipline usually doesn't make financial sense. Co-managed IT gives the internal team access to those specialists when they are needed.

7. Co-Managed IT Can Solve the Vacation Problem

Many organizations have a single IT manager or very small IT department. That creates a simple operational problem: What happens when the IT person goes on vacation? Someone still needs to respond if:

An employee can't access email
The internet goes down
A computer fails
A new employee starts
A cybersecurity alert occurs
A critical application stops working

Co-managed IT can provide backup coverage so employees have someone to call without requiring the internal IT employee to remain available during vacations.

8. Managed and Co-Managed IT Handle Cybersecurity Differently

Cybersecurity is a major responsibility in either model. With fully managed IT, the managed service provider may be responsible for deploying and managing security controls across the organization.

That may include:

Endpoint protection
Multifactor authentication
Email security
Microsoft 365 security
Patch management
Security monitoring
Backup
Employee security training

With co-managed IT, responsibility may be divided.

For example:

Internal IT

Company security policies
Application access
Employee approvals

MSP

Security monitoring
Endpoint protection
Microsoft 365 security configuration
Vulnerability remediation

This shared model can be especially effective when responsibilities are clearly documented.

9. Co-Managed IT Can Help Internal IT Become More Strategic

One of the strongest reasons to consider co-managed IT is not a technology problem. It is a time problem. Internal IT leaders often want to work on initiatives such as:

AI adoption
Automation
Cybersecurity improvements
Cloud strategy
Business intelligence
Workflow improvements
Infrastructure planning

Instead, their schedule gets consumed by support tickets and maintenance. By shifting some operational work to an MSP, the internal IT team can spend more time helping the business improve.

When Should a Business Choose Managed IT?

Managed IT is often the better fit when:

You do not have internal IT staff.
Employees rely on multiple outside vendors for support.
Technology problems are handled reactively.
Cybersecurity responsibility is unclear.
No one is consistently managing Microsoft 365.
Backups are not regularly monitored or tested.
Technology planning is not happening.
Your business needs predictable IT support.

For many small and midsize businesses, managed IT provides the capabilities of an IT department without having to build one from scratch.

When Should a Business Choose Co-Managed IT?

Co-managed IT is usually a better fit when:

You already have an IT manager or department.
Your IT team needs additional help desk capacity.
Projects keep getting delayed.
Your team needs specialized expertise.
Cybersecurity requirements are increasing.
Employees need after-hours support.
Your IT staff needs vacation coverage.
Hiring additional full-time employees is difficult.
You want access to enterprise-level IT tools.

Co-managed IT can be as narrow or comprehensive as the internal team needs.

Does Co-Managed IT Replace Internal IT Employees?

It should not. A good co-managed IT relationship is designed to make the internal IT team more effective.

The internal team maintains important knowledge about:

The company
Employees
Business processes
Applications
Leadership priorities

The MSP adds additional scale, expertise, tools, and support. Instead of asking, "What can we outsource?" a better question is: "Which responsibilities make the most sense for our internal team, and which could an outside partner handle more efficiently?"

Can You Switch From Managed IT to Co-Managed IT?

Yes. In fact, this is a natural progression for some growing companies. A small organization may initially outsource nearly everything to a managed service provider. As the company grows, it may hire an internal IT manager. Instead of ending the MSP relationship, the organization can transition to a co-managed model. The internal IT manager gains control of the areas that benefit from direct company ownership while continuing to use the MSP for specialized services, infrastructure, cybersecurity, or support.

What Services Can Be Included in Co-Managed IT?

Common co-managed services include:

Help desk
Microsoft 365 administration
Cybersecurity
Network monitoring
Endpoint management
Backup and disaster recovery
Cloud services
Project engineering
Documentation
Vendor management
After-hours support
Vacation coverage
IT strategy
Compliance support

There is no requirement that an MSP handle everything. The best co-managed relationships clearly define which team owns each responsibility.

Frequently Asked Questions About Managed and Co-Managed IT

What is managed IT?

Managed IT is an outsourced technology model in which a managed service provider handles most or all of a company's ongoing IT support, management, security, and technology operations.

What is co-managed IT?

Co-managed IT is a partnership between an internal IT department and an outside managed service provider. The two teams divide responsibilities based on the company's needs and the internal team's capabilities.

Is co-managed IT cheaper than managed IT?

It can be, but not always. Co-managed IT pricing depends on which services the outside provider handles. A company purchasing only monitoring and cybersecurity may spend less than one outsourcing help desk, cybersecurity, infrastructure, and projects.

Does co-managed IT mean outsourcing our IT department?

No. Co-managed IT is specifically designed to supplement existing IT employees rather than replace them.

Can an MSP work with a one-person IT department?

Yes. Organizations with one IT manager are often good candidates for co-managed IT because the MSP can provide backup coverage and skills that one individual cannot reasonably provide alone.

Who controls IT decisions in a co-managed relationship?

The business does. Responsibilities should be clearly defined, but the internal IT leader and company leadership retain control over technology decisions.
