What Is a Managed Service Provider (MSP)? Plain-English Guide and IT Glossary
Short answer: A managed service provider (MSP) is a company that takes ongoing responsibility for a business IT environment for a flat monthly fee. That typically includes 24/7 monitoring, help desk support, cybersecurity, backups and technology planning. Unlike break-fix IT, which charges when something breaks, an MSP works to prevent problems. In Charleston, managed IT typically costs $75 to $175 per user per month.
If you run a small business, you may keep hearing the term MSP without a clear explanation. Here is what a managed service provider does, how it differs from other IT options, when it makes sense to hire one, and a plain-English glossary of the IT terms you will run into.
What does a managed service provider do?
- Monitors your systems 24/7 so problems are caught before they stop work
- Provides a help desk so your team has someone to call for support
- Protects your business with cybersecurity tools, patching and email protection
- Backs up your data and tests that it can be restored
- Manages vendors, licenses and hardware so you deal with one contact
- Plans ahead with budgets, roadmaps and upgrades
