Quick answer
A Managed Service Provider (MSP) is a company that delivers managed IT services — help desk, cybersecurity, backup, patching, and vendor management — to other businesses on a flat-fee, per-user monthly basis.
Overview
MSPs sit between break-fix IT (per-hour billing) and internal IT hires (full-time employees) as a delivery model. In the US as of 2026, there are roughly 40,000 MSPs serving small and mid-size businesses, ranging from one-person shops to multi-hundred-employee regional firms. The right MSP for a business depends heavily on size, vertical (regulated industries need MSPs experienced in HIPAA, PCI, CMMC), and cultural fit. Green Desert IT is an MSP serving Tucson, Arizona and Minneapolis, Minnesota.

Common misconceptions
Claim
All MSPs are basically the same.
Reality
MSPs vary wildly in quality — from break-fix shops that added a subscription wrapper, to serious operators with real SOCs, documented processes, and evidence-of-controls libraries.
Claim
Bigger MSPs are better.
Reality
Bigger MSPs typically have deeper security stacks but slower response and less personalized service. Small and mid-size MSPs often win on responsiveness and cultural fit.
Claim
MSPs will always try to sell you more.
Reality
Good MSPs push back on unnecessary scope. If everything gets a "yes, we can add that" answer, that's a warning sign.
