The Two Models

Fully Managed vs Co-Managed, Defined

Fully managed IT means the MSP is your IT department: help desk, infrastructure, security, projects, and strategy at a per-user flat rate, with nobody internal owning IT day to day. Co-managed IT means your internal person or team stays — and stops drowning — while the provider carries monitoring, security operations, after-hours coverage, and overflow.

Both models are legitimate, both are common in Los Angeles, and choosing wrong wastes money in opposite directions. We run both every day, so this comparison includes the trade-offs the sales decks leave out.

  • Fully managed replaces the function; co-managed multiplies your existing team
  • Pricing differs by roughly 40% — but so does what you’re buying
  • The 50–150 employee range is where co-managed usually shines
  • Either model should include documented security — no exceptions

What We Carry — So Your Team Can Build

In a co-managed arrangement, the load divides cleanly. Here’s our side of it.

📡
24/7 Monitoring & SOC
Round-the-clock infrastructure monitoring and security operations — the always-on layer one internal person can never staff alone.
🛡️
Security Operations
EDR triage, patching, vulnerability management, and incident response — carried by a team that does nothing else.
🌙
After-Hours & Weekends
Nights, weekends, and vacations covered. Your IT manager takes a real vacation for the first time in years.
🎧
Overflow Help Desk
Ticket surges, onboarding waves, and the routine resets that eat your team’s project time.
📚
Documentation
Environment documentation built and maintained in systems you own — institutional knowledge that survives turnover.
🗺️
Roadmap Partnership
Your IT lead and our Technical Account Manager plan budgets and projects together — two perspectives, one plan.
Which Model Wins

Six Scenarios, Called Honestly

Match your situation — the answer usually declares itself.

01
No Internal IT At All
Fully managed, almost always. Under ~75 employees, a full internal hire is hard to justify and impossible to cover 24/7.
02
Your “IT Person” Wears Five Hats
Fully managed. An office manager doing IT part-time is a risk posture, not a strategy — free them to do their real job.
03
1–5 Good, Buried IT Staff
Co-managed. Keep the institutional knowledge, add depth and coverage. This is the classic 50–150 employee answer.
04
Projects Keep Slipping
Co-managed. When tickets eat every day, strategic work dies. We absorb the interrupt load; your team ships projects.
05
Compliance Outgrew One Person
Either model — but the security operations and evidence maintenance move to us. HIPAA, SOC 2, and Safeguards are team sports.
06
150+ Employees
Internal team plus co-managed security and after-hours. Staffing a real internal SOC starts around $500k/year — few need to.

Six Questions Before You Blend Teams

Co-managed only works with a provider who genuinely backs your staff. Test for it.

01
Will You Replace My IT Manager?
The wrong provider quietly competes with internal staff. Ask how many co-managed clients they serve — then call one.
02
Who Owns Documentation?
You do, in systems you can access — non-negotiable. Anything else is a hostage situation in progress.
03
How Does the Boundary Flex?
Scope should shift as your team grows or shrinks — without a renegotiation battle each time.
04
Can We Change Models Later?
Co-managed to fully managed (or reverse) should be a scope change, not a new contract. Companies shift as they grow.
05
How Do Escalations Work?
Your team and theirs need one queue, one severity language, and no “not our ticket” gaps. Ask to see the workflow.
06
Who Gets Credit?
Small question, big tell. Providers who make internal IT look good keep co-managed clients for a decade.
Frequently Asked Questions

Co-Managed IT Questions, Answered

What IT managers and owners ask when weighing the blend.

Will a co-managed MSP try to replace our IT manager?
The wrong one might. Ask how many co-managed clients they serve, talk to one, and read the contract: ours defines the internal team as the client we support, not the competition.
Can we start co-managed and go fully managed later — or the reverse?
Yes — it’s a scope change, not a new relationship. Companies commonly shift as they grow or as internal staff change.
Who owns documentation and passwords in a co-managed setup?
You do, in systems you can access. Any provider who resists is building a hostage situation.
Is co-managed cheaper than hiring another IT person?
Usually. A second engineer costs $110k+ loaded for one person’s skills and business hours; co-managed adds a whole team with 24/7 coverage for less. Full math: in-house vs managed IT costs.
How fast can a co-managed arrangement start?
Monitoring and security typically deploy within two weeks; help desk integration follows as documentation builds — fully running inside 30 days.
What does co-managed cost?
Typically $75–$150 per user per month depending on the split. Market context in our LA pricing guide.
