Co-Managed IT Services: How an MSP Works With Your Internal IT Team

A business does not have to choose between handling IT entirely in-house and handing everything over to an outside provider.

For companies that already have an internal IT employee or department, co-managed IT services provide a third option.

In a co-managed arrangement, your internal team remains involved in managing the business’s technology while an outside IT provider helps with specific responsibilities, expertise, projects, or capacity gaps.

That could mean additional network support, cybersecurity assistance, infrastructure management, help desk coverage, project support, or specialized technical expertise.

The important part is that the external provider does not automatically replace the internal team.

Instead, the two sides work from an agreed division of responsibilities.

For a growing business, this model can answer a practical question:

How can we give our IT team more capability without completely replacing the people who already understand our business?

What Are Co-Managed IT Services?

Co-managed IT services are a partnership between an internal IT team and an external managed service provider (MSP).

The internal team continues handling the responsibilities it is equipped to manage, while the MSP takes on specific areas where additional resources, expertise, tools, or coverage are needed.

The exact arrangement can vary significantly from one business to another.

For example, an internal IT team might continue handling:

• Employee support
• Day-to-day troubleshooting
• User accounts
• Application support
• On-site technology needs
• Internal IT projects

The external IT provider might support:

• Network monitoring
• Cybersecurity
• Infrastructure management
• Advanced troubleshooting
• Backup and recovery
• Network projects
• After-hours support
• Specialized technical work

The key is not the number of tasks assigned to each side.

The key is that responsibility is deliberately divided instead of duplicated or left unclear.

NewCom’s Managed IT Services offering covers areas such as network monitoring, administration, security updates, help desk support, and remote and on-site support. That type of capability can complement an internal IT function when a business needs additional capacity or specialized assistance.

How Does Co-Managed IT Work?

The process usually starts by identifying what the internal team already handles well and where gaps exist.

Consider a company with three internal IT employees.

The team may be capable of handling everyday employee support and maintaining business applications. However, the same team may struggle to provide continuous network monitoring, manage security tools, complete a large infrastructure project, or respond to complex issues while also keeping up with daily tickets.

Instead of replacing the team, the business can assign selected responsibilities to an MSP.

A simple structure might look like this:

Internal IT Team

→ Users and applications
→ Day-to-day support
→ Business-specific systems
→ Internal priorities

External MSP

→ Network monitoring
→ Specialized expertise
→ Security support
→ Escalation assistance
→ Infrastructure projects

Shared Responsibilities

→ Planning
→ Troubleshooting
→ Technology changes
→ Documentation
→ Strategic improvements

The exact division should be agreed upon before work begins.

That prevents one of the biggest problems with co-managed IT: two teams assuming the other team is responsible for the same issue.

Co-Managed IT vs. Fully Managed IT

The biggest difference is who retains primary responsibility for the IT environment.

With fully managed IT, the external provider takes responsibility for a much larger portion of the organization’s IT operations.

With co-managed IT, the business keeps its internal IT function and uses an external provider to supplement it.

Area	In-House IT	Co-Managed IT	Fully Managed IT
Internal IT team	Yes	Yes	Usually limited or none
External MSP	No	Yes	Yes
Internal control	High	High	Depends on agreement
Specialized expertise	Limited to internal resources	Added through MSP	Provided by MSP
Project capacity	Depends on team size	Can be expanded	Provided by MSP
After-hours coverage	Depends on staffing	Can be supplemented	Can be provided
Responsibility	Internal team	Shared by agreement	Primarily MSP
Flexibility	Based on internal capacity	High	Depends on service model

There is no universal model that fits every business.

The important question is whether the company’s current IT structure can consistently meet its operational and technology requirements.

Why Would a Business Need Co-Managed IT?

The need often appears gradually.

An internal IT team may have been perfectly capable when the company was smaller. Then the business adds employees, locations, cloud applications, network equipment, security requirements, and new technology.

The IT team grows more slowly than the environment it supports.

Eventually, the problem is not necessarily a lack of skill.

It is capacity.

Your IT team may know exactly what needs to be done but not have enough hours in the week to do everything.

Common signs include:

Your IT team has too many competing priorities

A network upgrade may keep getting pushed back because the team is busy handling daily support requests.

Important projects are delayed

Cloud migrations, infrastructure upgrades, security improvements, or office expansions may require more technical resources than the internal team can provide.

Specialized knowledge is missing

A business may need expertise in a particular networking, security, backup, cloud, or infrastructure area without needing another full-time employee with that specialization.

After-hours coverage is limited

A small internal team may not be able to provide continuous coverage without creating significant staffing demands.

The business is growing faster than the IT team

New employees, locations, devices, applications, and infrastructure can quickly increase the workload.

Security responsibilities are expanding

Security requires ongoing attention. Monitoring, patching, access controls, endpoint protection, backup planning, and incident response can become difficult to manage alongside everyday IT support.

These situations do not necessarily mean the internal IT team is failing.

They may simply indicate that the business has reached a point where additional IT capacity makes operational sense.

What Can an MSP Handle in a Co-Managed Arrangement?

There is no fixed checklist.

The most useful arrangement is based on the actual gap.

Network Monitoring and Infrastructure

An MSP can help monitor network infrastructure, identify issues, maintain systems, and provide additional troubleshooting expertise.

This can be particularly useful when the internal team has limited time for proactive infrastructure management.

For businesses dealing with network changes, office expansions, or physical infrastructure projects, Structured Wiring may also become part of the wider technology conversation.

The point is to look at the entire infrastructure rather than treating network hardware, cabling, and IT support as completely separate concerns.

Cybersecurity Support

Security is another area where an internal team may need additional depth.

An external provider can potentially assist with security monitoring, updates, vulnerability management, endpoint protection, security processes, or incident support depending on the engagement.

The exact services should be defined clearly because “IT support” and “managed security” are not automatically the same thing.

Advanced Troubleshooting

Internal IT staff often handle first-line support because they understand the company’s users and applications.

An MSP can provide escalation support when an issue requires deeper technical expertise.

This creates a useful structure:

Internal IT → First response → Escalation → MSP expertise

Instead of hiring a full-time specialist for every possible problem, the business can access additional expertise when it is needed.

IT Projects

Projects can create temporary workload spikes.

Examples include:

• Office moves
• Network upgrades
• Server changes
• Cloud migrations
• New location deployments
• Infrastructure upgrades
• Major software deployments

An MSP can supplement the internal team during these projects without becoming responsible for every aspect of daily IT operations.

Business Communications and Network-Connected Systems

IT responsibilities often extend beyond computers.

Business phone systems, network infrastructure, connectivity, and other technology can interact with the same environment.

For example, a company upgrading its communications infrastructure may need to consider its network, cabling, switches, phones, and ongoing IT support together.

NewCom’s Business Phone Systems services cover business VoIP and traditional phone systems as well as installation, maintenance, and related support.

This kind of cross-functional support can be useful when technology projects affect multiple parts of the business environment.

What Should Stay With the Internal IT Team?

This is one of the most important questions to answer before starting a co-managed arrangement.

Not everything should automatically be outsourced.

Your internal team may be the right group to retain responsibility for areas that depend heavily on company-specific knowledge.

For example:

• Business applications
• Employee relationships
• Internal processes
• Department-specific workflows
• Application permissions
• On-site coordination
• Business-specific technology decisions

The MSP can then focus on areas where external expertise or capacity adds more value.

This division can also change over time.

A business might initially outsource network monitoring, then later bring some responsibilities back internally after hiring additional staff.

Another company might keep day-to-day support internally while expanding the MSP’s role in security or infrastructure.

Co-managed IT should be flexible enough to change with the business.

How to Structure a Successful Co-Managed IT Relationship

The technology itself is only part of the equation.

The working relationship needs clear boundaries.

1. Define responsibilities

Document who handles common categories of work.

For example:

Responsibility	Internal IT	MSP
User support	Primary	Escalation
Network monitoring	Shared	Primary
Business applications	Primary	As needed
Security monitoring	Shared	Specialized support
Major infrastructure projects	Shared	Project support
Vendor coordination	Primary	As agreed
After-hours issues	As agreed	As agreed

The exact arrangement should reflect the business.

2. Establish escalation procedures

Everyone should know when an issue moves from the internal team to the MSP.

Without a clear escalation path, employees can end up contacting multiple teams for the same problem.

3. Document the environment

Both sides need access to accurate documentation.

That can include:

• Network diagrams
• Device inventories
• User information
• System configurations
• Vendor information
• Backup information
• Security procedures
• Contact details

Good documentation reduces confusion when responsibilities overlap.

4. Establish communication rules

Determine who communicates with employees, vendors, management, and other stakeholders.

The goal is to make the MSP feel like an extension of the IT function rather than a completely separate organization.

5. Define measurable responsibilities

Avoid vague statements such as “the MSP handles the network.”

Instead, define what that means.

Does the MSP monitor the network?

Does it handle alerts?

Does it maintain switches?

Does it troubleshoot outages?

Does it provide escalation support?

Does it manage specific projects?

Clear responsibilities create better accountability.

When Does Co-Managed IT Make Sense?

Co-managed IT can make sense when a business has an internal IT function but has identified a specific gap that is difficult or inefficient to solve entirely through additional internal staffing.

A useful starting point is to ask:

What is our IT team unable to consistently cover today?

Then break the answer into categories:

Capacity gap:
There are not enough hours to complete everything.

Expertise gap:
The team needs specialized knowledge.

Coverage gap:
The business needs support outside normal working hours.

Security gap:
The company needs additional security capability.

Project gap:
A major project requires temporary additional resources.

Infrastructure gap:
The business needs help with network, cabling, systems, or technology infrastructure.

If one or more of these gaps is persistent, co-managed IT may be worth evaluating.

What Does Co-Managed IT Cost?

There is no universal co-managed IT price because the service is built around the responsibilities the MSP takes on.

Cost can be affected by:

• Number of users
• Number of locations
• Existing IT staff
• Services being outsourced
• Network complexity
• Security requirements
• Monitoring requirements
• Project workload
• Required support hours
• Existing infrastructure
• Required response times

For that reason, comparing co-managed IT based only on a monthly per-user number can be misleading.

A better approach is to first define what problem the service is solving and what responsibilities the provider will actually own.

Then the business can compare the cost of the service against alternatives such as hiring additional staff, purchasing specialized tools, delaying projects, or leaving important responsibilities uncovered.

Co-Managed IT for Businesses in Westlake and the Conejo Valley

For businesses in Westlake Village, Thousand Oaks, Agoura Hills, Calabasas, Simi Valley, and the broader Conejo Valley, IT requirements can change significantly as companies add employees, locations, systems, and network infrastructure.

A business with an established internal IT employee may not need to replace that role.

Instead, it may need additional technical capacity around the existing team.

For example, an internal IT manager could continue managing users and business applications while an external provider helps with network monitoring, infrastructure projects, security updates, or specialized troubleshooting.

Another company may need support temporarily while opening a new office.

The right arrangement depends on the existing team, infrastructure, technology requirements, and business priorities.

How to Evaluate a Co-Managed IT Provider

Before entering an agreement, ask practical questions.

What exactly will you manage?

Get specific.

Avoid an agreement where responsibilities are described only in broad terms.

How will you work with our existing IT team?

The provider should understand that the internal team remains an important part of the environment.

Who owns each responsibility?

Make sure there is no ambiguity around monitoring, troubleshooting, security, projects, vendors, and escalation.

What happens when something goes wrong?

Understand the escalation process and who communicates with whom.

Can the service change as our needs change?

Your requirements may change after six months or a year.

The arrangement should be able to adapt.

How will success be measured?

Consider response times, project completion, system availability, monitoring coverage, ticket volume, security tasks, or other measurable outcomes relevant to the engagement.
