What co-managed IT includes

Co-managed IT services combine an internal IT team with an external managed service provider (MSP) to share technology responsibilities. The MSP typically handles 24/7 monitoring, cybersecurity, after-hours support, escalation triage, and strategic planning, while the internal team manages day-to-day operations, user support, and business-specific applications. This model fills skill and coverage gaps without replacing existing IT staff.

TL;DR

A co-managed IT model pairs your internal IT team with an external MSP to fill coverage gaps—typically after-hours monitoring, cybersecurity, escalation support, and strategic planning. Fusion Computing’s co-managed practice augments internal IT departments with 24/7 NOC coverage, CISSP-certified security expertise, and vCIO advisory—without replacing your existing staff.

Co-managed IT includes monitoring, security, vendor management, and on-call support. It’s a hybrid IT support model that fills the depth gaps a single IT person can’t cover. Businesses report better IT stability after implementing these layers of managed support.

How we split the work: clearly, from day one

A business should choose co-managed IT when it has an internal IT person who handles day-to-day operations but needs help with cybersecurity, after-hours monitoring, cloud management, or strategic planning. The model fills skill gaps without replacing your existing team. It’s ideal for companies with 50–200 employees outgrowing a single IT hire.

According to ISC2’s 2025 Cybersecurity Workforce Study, the global cybersecurity workforce gap stands at 4.8 million unfilled positions, with 59% of organizations reporting critical skills shortages. Fewer than 15% of companies are confident they have the people they need. Co-managed IT bridges this gap without the cost and delay of full-time hiring.

Clear role definition prevents costly gaps. Without clear ownership, tickets fall between teams and nobody owns the outcome. With a documented split, your team and Fusion both know exactly where responsibility starts and ends.

“Co-managed works best when the internal IT person is good but overwhelmed. They know the business, they know the users, but they’re drowning in tickets and can’t get to the projects that actually move the needle. We take the reactive work off their plate.”

— Mike Pearlstein, CISSP, CEO of Fusion Computing

The split is flexible. Some clients hand Fusion most of the operational load. Others keep most support in-house and use Fusion for security, after-hours, and overflow.

Co-managed, fully managed, or staff augmentation: what fits

According to Sophos’s 2025 Cybersecurity Burnout report, 76% of IT and cybersecurity professionals experienced burnout in the past year, with 85% saying they expect to leave their role because of it. Internal teams are stretched past capacity. Co-managed IT shares the operational load so your best people stay engaged instead of heading for the exit.

Co-managed IT divides responsibility: your team handles daily operations, Fusion owns strategy, security, and escalations. Best for 60+ person teams. Fully managed suits smaller companies. Staff augmentation fills skill gaps temporarily. Co-managed IT augments your existing team with operational depth.

A controlled first 90 days: integration, not disruption

According to BetterCloud’s 2024 research, the average IT-to-employee ratio has reached 1 IT person for every 108 employees—meaning internal teams manage more endpoints, apps, and security threats than ever. That workload creates blind spots. Co-managed IT adds specialized capacity exactly where your team is thinnest, without adding headcount.

Smooth transitions matter. Fusion’s phased approach ensures zero downtime for critical systems while your team learns new processes. Done right, the transition is invisible to end users.

Your IT person stays involved the entire time. The goal is to make their job better, not to replace them.

What co-managed IT costs

According to ISC2’s 2024 Cybersecurity Workforce Study, 33% of organizations lack the budget to adequately staff their security teams, and 25% reported cybersecurity layoffs in the past year. Budget-constrained companies face a double bind: they can’t hire, but they can’t go unprotected. Co-managed IT provides enterprise-grade coverage at a fraction of full-time cost.

Co-managed IT typically ranges from $120–$250 per user per month. Most clients find they’re getting more coverage than a comparable hire would deliver, without the overhead of salary, benefits, and onboarding.

Co-managed IT in practice

According to Canalys’s 2025 MSP Trends report, the managed services industry is shifting toward MSP 3.0—a co-managed, cloud-first model where partners augment internal teams rather than replace them. Global managed services revenue will reach $595 billion in 2025. The future of IT isn’t outsourced or in-house. It’s both, working together.

Your team owns day-to-day troubleshooting; Fusion owns firewall management, security patch deployment, backup integrity, and capacity planning. You’re each working in your lane. Weekly syncs keep both teams aligned, and monthly strategy reviews adjust the roadmap.

Who co-managed IT works best for

Co-managed IT works best for businesses between 30 and 500 employees that already have an IT person but don’t have enough depth for security, after-hours, and escalations. Think of it as augmented IT support: Fusion extends your internal team’s reach without replacing them. If your IT lead is the only person on call, they’re carrying a weight the business can’t sustain.

How co-managed IT augments your internal team

Co-managed IT services are designed for businesses that already have internal IT staff but need to fill coverage gaps. The most common gaps are after-hours monitoring, cybersecurity expertise, escalation support, and strategic planning. Co-managed IT doesn’t replace your team—it gives them the depth and backup they need to operate at a higher level.

Hybrid IT support models let your internal team focus on business-specific projects and user relationships while the MSP handles the operational workload: 24/7 monitoring, patching, backup verification, and security tooling. This augmented IT support approach is typically 40–60% less expensive than hiring additional full-time staff, while providing broader skill coverage and eliminating the single-point-of-failure risk of a small internal team. Fusion’s co-managed practice works alongside your existing IT staff to supplement internal IT team capabilities without the politics of a full outsourcing transition.

What is co-managed IT?
Co-managed IT is a model where Fusion works alongside your internal IT team rather than replacing them. Your IT staff keeps ownership of projects and priorities. Fusion handles monitoring, patching, security, after-hours coverage, vendor management, and overflow support. It’s a good fit for businesses in the 30–150 employee range that have a small IT team or a single IT generalist who’s stretched thin.
Will Fusion try to replace our IT person?
No. Co-managed IT exists specifically to support internal IT teams, not replace them. Your IT person keeps ownership of strategy, projects, and the relationships they’ve built. Fusion handles the operational load so your internal team can focus on work that’s actually moving the business forward.
How do we decide who handles what?
During the first two weeks, Fusion builds a shared responsibility matrix with your IT lead. Common splits: Fusion takes monitoring, patching, security, backups, and after-hours. Your team keeps projects, user-facing support, and business app administration. It’s documented and adjustable at regular reviews, so you’re not locked into the initial scope.
Can Fusion work inside our existing ticketing and support tools?
Yes. Support tooling follows the client environment. Fusion documents the service stack and can work within platforms like ConnectWise, NinjaOne, Huntress, and zofiQ when they fit the operating model. Documented escalation paths and SLA tracking are established regardless of platform, so we don’t force a tool swap.
What happens after hours and on weekends?
Fusion provides after-hours monitoring, escalation, and support as scoped during onboarding. For co-managed environments, this typically covers critical system alerting, triage, and resolution so your IT person isn’t the sole point of contact outside business hours. Expectations and escalation paths are defined during the first 90 days.
What security tools does Fusion bring to a co-managed engagement?
The documented co-managed security stack follows CIS Controls v8.1 baselines and can include Huntress managed detection and response, Fortinet firewall management, endpoint protection, and automated patch management. Fusion also handles security awareness training delivery, backup verification, and compliance-supporting documentation for private-sector PIPEDA and cyber insurance renewals. If you’re pursuing cyber insurance, we’ll document what’s in place so the process doesn’t stall.
How much does co-managed IT cost?
Co-managed IT pricing depends on how much Fusion owns: after-hours coverage, helpdesk overflow, patching, security tooling, vendor coordination, number of users and endpoints, and number of sites. Because co-managed scopes vary widely, Fusion doesn’t apply a generic per-user number. We price the engagement after assessment so you’re not paying for coverage you don’t need. Book an IT assessment for a scoped estimate →
What if our IT person leaves?
It’s one of the strongest reasons to have a co-managed partner. Because Fusion already knows your environment, has documentation, and manages core infrastructure, a departure doesn’t become an emergency. Fusion can expand coverage immediately while you decide whether to rehire or move to fully managed, and you don’t have to make that call alone.
What is the difference between co-managed IT and fully managed IT?
With fully managed IT, Fusion acts as your complete IT department. With co-managed IT, Fusion works alongside your existing internal IT team to supplement internal IT team capacity and fill specific gaps: typically security, after-hours coverage, vendor management, and escalation support. Many Fusion clients start with co-managed and transition to fully managed as their needs grow, so they don’t have to guess at the handoff. See fully managed IT services →
