Solutions / Co-Managed IT
Co-Managed IT Services
Keep your IT person. Give them a team. Co-managed IT pairs your internal staff with ACS's 24/7 monitoring, helpdesk overflow, security stack, and senior engineers — so nothing depends on one person.
What is co-managed IT?
Co-managed IT services supplement your existing internal IT staff with an outside partner's tools, monitoring, security stack, and engineers — you keep control and institutional knowledge, and gain 24/7 monitoring and depth. Fully managed IT replaces the internal role entirely; in-house-only IT carries everything alone. Co-managed sits in between, and it's how a one-person IT department becomes a team.
When co-managed IT is the right model
You don't have to choose between an internal team and an MSP. The strongest setups use both.
One-person IT department
Your IT manager is excellent — and a single point of failure. Vacations, sick days, and 2am alerts shouldn't depend on one phone.
Security has outgrown the team
EDR, SOC monitoring, dark-web watch, and insurer control sets are full-time jobs. We bring the stack; your team keeps control.
Projects keep stalling
Migrations, refreshes, and rollouts die when the day-to-day queue never empties. We absorb the queue or the projects — your call.
Coverage gaps
Nights, weekends, multiple sites, or a growing headcount your team can't reach fast enough.
How we split the work
Co-managed IT services are scoped around your team, not instead of it. Typical splits:
You lead, we cover
Your team owns strategy and day-to-day support. ACS adds 24/7 monitoring, patching, backup management, the security stack, and after-hours + overflow helpdesk.
You run support, we run projects
Your team keeps the helpdesk. Our senior engineers deliver the migrations, refreshes, and compliance work that never fit the week.
You operate, we certify
We own the risk analysis, HIPAA documentation, and insurer control set; your team runs day-to-day with our tooling.
Every co-managed engagement includes the same tooling our fully managed IT clients get — RMM, EDR, immutable backups, documentation — licensed to your environment, visible to your team.
Co-managed vs fully managed vs in-house
The honest comparison, so you pick the right model — even if it isn't ours.

Co-managed IT: questions, answered
Is co-managed IT trying to replace our IT person?
No — the model only works with your internal team in place. We add capacity, coverage, and a deeper security stack around them. Many of our longest engagements started because an IT manager wanted backup, not a replacement.
What does co-managed IT cost?
Flat per-seat pricing, scoped lower than full management because your team carries part of the load. See pricing or book a free assessment for a real number.
Who owns the tools and documentation?
Your environment, your visibility. Your team gets access to the RMM, monitoring, and documentation we maintain — no black boxes, no hostage-taking if we ever part ways.
Can co-managed turn into fully managed later (or vice versa)?
Yes. The scope flexes as your team changes — practices often move between fractional, co-managed, and fully managed as they grow.
Do you co-manage with healthcare IT teams?
Constantly — it's our specialty. We bring the HIPAA compliance layer, EHR vendor coordination, and clinical-urgency response most internal teams can't staff alone.
