 GLOSSARY · General IT 

#  Managed Service Provider MSP 

 A company that proactively manages a client's IT infrastructure and end-user systems for a recurring fee, instead of charging hourly when things break. 

## Detailed definition

A **Managed Service Provider** (MSP) is a third-party firm that takes responsibility for the day-to-day operation of a client’s IT environment under a recurring contract — typically a flat monthly fee per user or per device. Rather than charging the client by the hour every time something breaks (the “break-fix” model), an MSP is on the hook for keeping things running.

## What an MSP typically covers

The exact scope varies, but most managed-IT contracts include:

* **Patching and updates** for operating systems, third-party software, and firmware
* **Endpoint monitoring** — uptime, disk health, performance, security alerts
* **Helpdesk** — a phone number and email address users can actually reach
* **Backup verification** — proving the backups would actually restore if needed
* **Security management** — MFA, EDR, identity, access reviews
* **Vendor coordination** — talking to ISPs, hardware vendors, SaaS support so the client doesn’t have to

## Why businesses pick managed over break-fix

The economic argument is incentive alignment. Under break-fix, the IT provider only makes money when something goes wrong — there’s no profit in stopping fires before they start. Under a managed contract, the provider eats the cost of every after-hours emergency, so they’re motivated to prevent them. Patching gets done. Monitoring gets watched. Backups get tested.

The trade is **predictability versus variability**. Managed clients pay a known monthly number; break-fix clients pay nothing in good months and very large numbers in bad ones.

## What an MSP is _not_

* **Not a cloud provider.** An MSP manages your AWS / Azure / Google Cloud accounts, but doesn’t own the underlying infrastructure.
* **Not a software vendor.** Most MSPs resell Microsoft 365, Google Workspace, SonicWall, Bitdefender, and similar through partner programs — but they’re not the maker of those products.
* **Not a staffing firm.** MSPs are outcome-based; staff augmentation firms place individuals into your team and bill by the hour.

## When an MSP fits and when it doesn’t

The model fits best for organizations that:

* Don’t have or need a full-time internal IT person (typically under \~50 employees)
* Want predictable IT costs as a line item
* Have compliance requirements (HIPAA, PCI DSS) where consistency matters
* Want a single throat to choke when something breaks

It fits less well for:

* Very small shops (under 5 people) where ad-hoc support is cheaper
* Large enterprises with a real IT team that just needs specialist help on demand
* Anyone whose tech stack is so unusual that no MSP has credible expertise in it
