Co-Managed IT vs. Fully Outsourced IT: Which Model Is Right for Your Business?

Most people think the difference between co-managed IT vs fully outsourced IT is pretty clear. With co-managed IT, you keep an internal IT function and bring in outside support. With fully outsourced IT, an outside provider takes on a broader share of IT responsibilities. In practice, there’s a lot of room between those two models. 

A company might outsource its help desk so its internal IT professionals have more time for strategic projects. Another might keep day-to-day support in-house while choosing a managed IT provider to handle cybersecurity, infrastructure, and other specialized IT needs. How those responsibilities are divided depends on your existing resources, where you need additional support, and how much responsibility you want an outside provider to assume. 

What Is Co-Managed IT? 

Co-managed IT combines your internal IT resources with support from a managed service provider (MSP), with responsibilities divided based on what you want to keep in-house. Your internal IT professionals might manage business applications and technology planning while an MSP handles the help desk, cybersecurity monitoring, and infrastructure. Or you might keep user support in-house and bring in additional resources for security, cloud services, major technology projects, and other specialized areas. 

There’s no standard formula for dividing the work. Your internal IT resources stay actively involved, while the provider adds capacity and specialized resources where you need additional support. 

What Is Fully Outsourced IT? 

With fully outsourced IT, an outside provider handles a broader portion of your IT operations, which could include user support, infrastructure management, cybersecurity, system monitoring, and technology planning. Organizations without dedicated internal IT resources may use this model to cover functions they would otherwise have to build and staff internally. It can also work for organizations that have some internal resources but want a provider to handle most IT operations. 

Business leaders still play an important role in setting priorities, assessing risk, and determining where technology investments should support the organization. The provider handles the agreed-upon day-to-day and technical work while staying aligned with those priorities. 

Co-Managed IT vs. Fully Outsourced IT at a Glance 

The responsibilities will vary by organization, but the two IT support models generally compare like this: 

Area	Co-Managed IT	Fully Outsourced IT
Internal IT resources	Remain actively involved	May be limited or absent
Day-to-day support	Divided between internal IT and the provider	Provider handles a broader share
Cybersecurity	Responsibilities can be shared	Provider assumes broader responsibility
Specialized IT needs	Supplements internal capabilities	Primarily provided through the outsourced relationship
IT strategy	Internal IT and the provider collaborate	Provider works with business leadership
Scope	Responsibilities are divided according to your needs	Provider handles a broader portion of the IT environment

Co-managed arrangements in particular can take many forms. You might outsource routine help desk support while keeping technology strategy in-house, or handle user support internally while relying on your provider for cybersecurity and infrastructure. Two organizations using co-managed IT could divide those responsibilities very differently. 

When Co-Managed IT May Fit Your Organization 

If you want to retain your internal IT resources while adding capacity or specialized knowledge, several situations may point toward a co-managed model: 

• Routine support is taking time away from other priorities: Moving help desk requests or other recurring work to an MSP gives internal resources more time for projects and planning. 
• You need additional technical resources: An outside provider can supplement internal knowledge in cybersecurity risk management, cloud infrastructure, networking, or other technical areas.
• Your organization is growing: Additional employees, systems, locations, and technology requirements can increase the workload without requiring you to staff every function internally. 
• You want to retain institutional knowledge: Internal IT stays closely involved while the provider takes responsibility for specific parts of the technology environment. 

The balance can change over time as your internal capacity and technology needs evolve. 

When Fully Outsourced IT May Fit Your Organization 

Organizations that want a provider to handle a larger share of their technology environment may consider fully outsourced IT when: 

• You have little or no dedicated internal IT function: An outside provider supplies resources across the IT areas included in the relationship. 
• Your existing resources cover only part of your IT needs: The provider can take responsibility for areas your internal resources don’t have the capacity or technical background to support. 
• Your IT environment has expanded: More users, locations, systems, and security requirements can change how much support the organization needs. 
• You want to consolidate IT responsibilities: A broader outsourced relationship places a larger portion of ongoing IT operations with one provider. 

Whichever approach you use, responsibilities should be defined from the start. That includes expectations around support, cybersecurity, escalation, strategic planning, and decision-making. 

Questions to Ask Before Choosing an IT Support Model 

Your current IT environment can tell you a lot about which approach fits your organization. As you compare co-managed and fully outsourced IT, consider: 

• Where is your internal IT function spending most of its time? 
• Which technology priorities keep getting pushed aside? 
• Where do you need additional capacity or technical resources? 
• Which IT responsibilities do you want to keep internally? 
• How much responsibility do you want an outside provider to assume? 

Your answers may point toward one model or toward an arrangement somewhere in between. 

Finding the Right IT Support Model for Your Organization 

Co-managed and fully outsourced IT offer different ways to divide technology responsibilities between your organization and an outside provider. Your existing resources, technical needs, business priorities, and plans for growth all factor into where that dividing line should fall.
