What is Co-managed IT?
Co-managed IT is a hybrid service model in which a business's in-house IT team continues to run day-to-day support while an outside Managed Service Provider (MSP) provides after-hours coverage, tier-3 escalation, security tooling, and project delivery — without replacing the internal team.
Quick answer
Co-managed IT is a hybrid service model in which a business's in-house IT team continues to run day-to-day support while an outside Managed Service Provider (MSP) provides after-hours coverage, tier-3 escalation, security tooling, and project delivery — without replacing the internal team.
Overview
Co-managed IT emerged as a middle path for businesses with 1–3 internal IT staff who couldn't cover 24/7 alone but weren't ready (or willing) to fully outsource IT to an MSP. The internal team keeps the roadmap, the client relationships, and the ticket queue; the MSP contributes bench depth — usually a security stack (EDR, MDR, backup), after-hours P1 coverage, tier-3 escalation for hard tickets, and delivery capacity for major projects like M365 migrations. As of 2026, co-managed is one of the fastest-growing segments in MSP service delivery, especially among mid-market firms with 50–200 employees.
What Co-managed IT includes
- Alignment agreement
- A documented scope defining who owns what — internal IT vs the MSP.
- Shared tooling
- The MSP's security stack (EDR, MDR, backup) deployed to the client's environment; internal IT gets console access.
- Escalation runbook
- Documented criteria for which tickets flow from internal IT to the MSP for handling.
- Coverage window
- Defined after-hours support boundary — typically P1 (critical) only overnight, wider coverage on weekends.
- Project bench
- MSP capacity to deliver scoped projects (migrations, hardware refresh) that would otherwise consume internal IT time.
Common misconceptions
Claim
Co-managed will make our internal IT person obsolete.
Reality
The opposite. Co-managed makes internal IT more effective by removing the 24/7 burden and providing bench depth for specialized work.
Claim
Co-managed is more expensive than fully-managed.
Reality
Usually less. Co-managed retainers are typically 20-40% of fully-managed pricing, since you're only paying for the parts the internal team doesn't cover.
Claim
Co-managed only works for big companies.
Reality
It works particularly well for businesses with 50–200 employees and one to three internal IT people. Under 50 users usually goes fully managed; over 300 usually builds a full internal team.
