What is co-managed IT and is it right for my business?
Co-managed IT partners an external MSP with your internal IT team. Learn when it makes sense, how it works, and how it compares to fully managed services.
Key Takeaways
- Co-managed IT combines your internal IT team's institutional knowledge with an MSP's specialized expertise and 24/7 coverage
- Co-managed arrangements typically cost 30-40% less than fully managed services while maintaining internal strategic control
- The model works best for companies with 50-500 employees who have some IT staff but need additional depth
- Common co-managed services include cybersecurity, help desk overflow, after-hours support, and strategic planning (vCIO)
- Success depends on clearly defining which responsibilities belong to each team to avoid gaps or overlap
You have an internal IT person (or a small team), and they do solid work. But they’re overwhelmed. They can’t be experts in everything. They don’t have 24/7 coverage. And strategic projects keep getting pushed aside because daily firefighting consumes all their time.
Fully outsourcing IT feels wrong - you’d lose the institutional knowledge and personal relationships your internal team has built. But the status quo isn’t sustainable.
That’s exactly the gap co-managed IT fills.
What Is Co-Managed IT?
Co-managed IT is a hybrid service model that pairs your internal IT team with an external managed service provider (MSP). Instead of replacing your IT staff, the MSP supplements them with specialized expertise, additional capacity, and tools they wouldn’t have access to on their own.
Think of it as adding depth to your roster without the cost of hiring multiple specialists.
How It Differs From Other Models
| Model | Description | Best For |
|---|---|---|
| Break-fix | Call someone when things break, pay per incident | Very small businesses with simple needs |
| Fully managed | MSP handles all IT functions | Companies without internal IT staff |
| Co-managed | MSP supplements your existing IT team | Companies with internal IT that need additional depth |
| Internal only | All IT handled by employees | Large enterprises that can afford full IT departments |
How Co-Managed IT Works in Practice
The beauty of co-managed IT is its flexibility. You and the MSP define which responsibilities each team handles, based on your internal team’s strengths and your business needs.
Common Responsibility Splits
Your Internal Team Handles:
- Day-to-day user support and relationship management
- Business-specific application management
- Internal project coordination
- Institutional knowledge and context
- Strategic priorities aligned with business goals
The MSP Handles:
- Cybersecurity - SOC monitoring, threat detection, incident response, vulnerability management
- Help desk overflow - handling tickets when your team is swamped or unavailable
- After-hours and weekend support - 24/7 coverage without burning out your team
- Infrastructure management - server monitoring, patch management, network optimization
- Cloud management - Microsoft 365 administration, Azure/AWS management
- Strategic planning (vCIO) - technology roadmapping, budgeting, vendor evaluation
- Compliance support - audit preparation, policy development, framework alignment
- Specialized projects - migrations, deployments, and initiatives requiring expertise your team doesn’t have
The split is customized. One company might keep all end-user support internal and outsource security. Another might keep servers and networks internal but outsource the help desk and strategic planning.
When Co-Managed IT Makes Sense
Company Size: 50-500 Employees
At this size, you typically have 1-5 IT staff. That’s enough for daily operations but not enough for comprehensive security, 24/7 coverage, AND strategic planning.
You Have Good IT People
Co-managed IT works when your internal team is competent but capacity-limited. If you don’t trust your internal IT at all, fully managed services may be a better fit.
Specialized Needs Exceed Internal Skills
Your IT generalist handles networking, help desk, and desktop support capably. But cybersecurity requires dedicated expertise. Cloud architecture needs specialized knowledge. Compliance demands framework-specific experience. These are the areas where an MSP supplements effectively.
You Need 24/7 Coverage
Your IT team works 8 AM to 5 PM. Your business operates across time zones, or critical systems need monitoring around the clock. An MSP provides after-hours coverage without requiring you to hire shift workers.
Budget Constraints
Hiring a cybersecurity specialist ($90-130K salary + benefits), a cloud engineer ($100-140K), and a part-time vCIO ($80-120K) would cost $270-390K annually. A co-managed MSP can provide access to all these specialties for a fraction of that cost.
The Cost Comparison
| Model | Typical Monthly Cost (100 employees) | What You Get |
|---|---|---|
| Fully managed IT | $15,000-25,000 | Complete IT outsourcing |
| Co-managed IT | $8,000-15,000 | Supplemental expertise, 24/7 coverage, security |
| Internal only (equivalent capability) | $25,000-40,000 | Salaries for 3-4 specialists + tools |
Co-managed arrangements typically save 30-40% compared to fully managed services while maintaining your internal team’s strategic control and institutional knowledge.
The savings come from precision: you’re not paying the MSP for functions your internal team handles well. You’re paying for specific capabilities that would be expensive and impractical to build in-house.
Making Co-Managed IT Work
Define Clear Boundaries
The most common failure point is ambiguity about who handles what. Without clear definitions, issues fall through cracks or get duplicated.
Create a responsibility matrix:
| Function | Internal Team | MSP | Shared |
|---|---|---|---|
| Desktop support (business hours) | Primary | Overflow | |
| Desktop support (after hours) | Primary | ||
| Server management | Primary | Monitoring | |
| Network management | Primary | Monitoring | |
| Cybersecurity | Primary | Incident response | |
| Microsoft 365 administration | Primary | ||
| User onboarding/offboarding | Primary | Template setup | |
| Strategic planning | Primary (vCIO) | Joint quarterly reviews | |
| Vendor management | Primary | Recommendations |
Establish Communication Protocols
- Shared ticketing system so both teams see the same queue
- Regular sync meetings (weekly or bi-weekly) between your IT lead and the MSP’s account manager
- Clear escalation paths for both teams
- Shared documentation in a common knowledge base
- Defined SLAs for the MSP’s responsibilities
Integrate Tools and Systems
Both teams need visibility into the same systems:
- Shared monitoring dashboards
- Common remote access tools
- Integrated ticketing and documentation
- Shared security dashboards and alerting
Protect Your Internal Team
Co-managed IT should feel like reinforcement, not replacement. Your internal team should:
- Be involved in selecting the MSP partner
- Help define the responsibility split
- Maintain ownership of strategic decisions
- Have their workload reduced in the areas the MSP covers, freeing them for higher-value work
- Grow professionally through exposure to the MSP’s specialized knowledge
Common Co-Managed IT Concerns
”Will my IT person feel threatened?”
They shouldn’t. Frame co-management as giving your IT team superpowers, not replacing them. They get access to specialized tools, 24/7 backup, and expertise in areas they’ve wanted to develop but haven’t had time for.
”How do we handle disagreements?”
Define decision rights upfront. Typically, the internal team has final say on business-specific decisions, while the MSP has authority in their areas of expertise (security configurations, best practices, compliance requirements).
”What if we outgrow the MSP?”
A good co-managed relationship evolves. As your internal team grows, the MSP’s role may shift toward more specialized functions. The flexibility to adjust is a feature of the model.
The Bottom Line
Co-managed IT isn’t about replacing your IT team - it’s about making them more effective. By offloading specialized functions like cybersecurity, after-hours support, and strategic planning to an MSP, your internal team can focus on the work that benefits most from their institutional knowledge and business relationships.
The model works best when responsibilities are clearly defined, communication is structured, and both teams share a common goal: keeping your business running securely and efficiently.
If your IT team is talented but stretched thin, co-managed IT might be the smartest investment you make this year.
