What is a managed service provider? A managed service provider, or MSP, is a company that runs part or all of another business's IT for a recurring fee. Instead of calling someone when something breaks, the customer pays for ongoing monitoring, support and maintenance, and the MSP is responsible for keeping systems working.
That is the short answer. The longer one matters, because "managed service provider" covers a lot of different businesses, from a three-person local shop to a firm that runs infrastructure for hundreds of companies. This guide explains what an MSP does, how the model works, what it costs in structure, how it differs from the alternatives, and what examples look like in practice.
What does a managed service provider do?
An MSP takes responsibility for outcomes, not individual tickets. Most MSPs offer a mix of the following:
- Helpdesk and user support. Staff can phone or message the MSP when something does not work.
- Monitoring and maintenance. Tools watch servers, laptops and networks, and the MSP patches and fixes issues before users notice.
- Network management. Firewalls, switches, wireless and internet connections are set up and watched.
- Cloud services. Email, file storage and business applications are moved, configured and managed.
- Backup and recovery. Data is copied on a schedule and restored when needed.
- Security. Protection, updates, user training and sometimes monitoring, which can extend into a managed security service.
- Vendor management. The MSP deals with software and hardware suppliers on the customer's behalf.
- Planning. Regular reviews of the technology roadmap, risks and budget.
How does the MSP model work?
The model rests on three ideas. First, work is proactive: tools collect signals and technicians act before a failure grows. Second, the relationship is a contract with defined scope, targets and reporting, usually called a service level agreement. Third, pricing is recurring, so the MSP earns a steady income by keeping the customer's systems healthy rather than by fixing breakages.
Most MSPs run on a standard set of software: a remote monitoring and management tool to watch and patch devices, a professional services automation tool to track tickets, contracts and billing, plus security, backup and documentation tools. That stack is also why MSPs are a valuable audience for software vendors, a point we come back to below.
How do MSPs charge?
Pricing differs by provider, but the structures are common:
| Model | How it works | Good fit when |
|---|---|---|
| Per user | A fee for each person supported | Staff numbers drive most of the work |
| Per device | A fee for each laptop, server or network device | The estate is device heavy |
| Tiered bundle | Packages with set services at each level | The customer wants simple choices |
| Flat fee | One monthly amount for a defined scope | The scope is stable and well understood |
| Project plus retainer | Fixed price for a migration, then ongoing support | A big change is planned |
Whatever the structure, read what sits outside it. Projects, after-hours work and special systems are the usual places where an unexpected charge appears.
How is an MSP different from other IT options?
- Break-fix. You call a technician when something fails and pay for the time. It can be cheap in a quiet month and expensive in a bad one, and nobody is watching for trouble.
- In-house IT. You employ your own staff. You get close knowledge of the business, but one or two people cannot cover every skill or every hour.
- Co-managed IT. Your team handles day-to-day work and an MSP adds tools, specialist skills and out-of-hours cover.
- Managed security provider. A provider that focuses on protection and monitoring. Our guide to MSP vs MSSP explains where the two overlap and differ.
What are examples of managed service providers?
Rather than naming companies, here are the main kinds you will meet. The scenarios are illustrative.
- Small local MSP. A handful of technicians supporting local offices, such as a dental practice or an accounting firm, with onsite visits and a personal relationship.
- Regional MSP. A larger team covering several cities, with a service desk, a security offer and project engineers.
- Vertical specialist. An MSP that serves one industry, such as healthcare, legal or manufacturing, and understands its software and compliance needs.
- Cloud MSP. A provider focused on running and optimizing workloads in the public cloud.
- Managed security service provider. A provider centered on monitoring, detection and response. See our managed security service provider list.
- Staffing MSP. A different use of the same letters: a company that manages a client's contingent workforce program, covered in our top staffing MSP providers page.
What is a managed service company?
A managed service company is another name for an MSP. People also say managed services provider, managed IT services company or IT managed service provider. The words differ and the idea is the same: a company that manages technology services for customers under a recurring agreement.
What does the managed service provider industry look like?
The industry is made of three groups. Customers buy managed services. Providers deliver them. Vendors supply the tools providers run, which includes software for monitoring, security, backup and billing. Vendors reach providers through distributors, resellers, marketplaces and direct sales teams, and many join partner programs.
That structure is why a clean list of providers has value. Our database covers about 100,000 MSPs across 60+ countries, which gives vendors a way to find providers by location, size and the tools they run. You can explore it on our MSP database page.
How do you choose a managed service provider?
- Write down what you need covered and what you want to keep in-house.
- Shortlist providers with experience in your industry and size.
- Ask for the service levels in writing, including response and resolution times.
- Ask how security is handled and which standards they follow.
- Speak with current customers of a similar size.
- Read the exit terms before you sign.
Our fuller guide, how to choose an MSP, walks through each step with questions to ask.
When does an MSP make sense?
An MSP is usually a fit when downtime costs more than the monthly fee, when you need skills you cannot hire full time, when security and compliance demands are rising, or when the person who "does the IT" is also doing another job. It is a weaker fit if you have a large in-house team with all the skills and tools you need, though co-managed arrangements can still help.
