A managed service provider (MSP) is a third-party company that remotely manages a customer’s information technology (IT) infrastructure and end-user systems. Small and medium-sized businesses (SMBs), nonprofits and government agencies hire MSPs to perform a defined set of day-to-day management services. These services may include network and infrastructure management, security and monitoring.

MSPs often handle management services on a daily basis so customer organizations can focus on improving their services without worrying about extended system downtimes or service interruptions.
