A Managed Service Provider (MSP) is a company, like SupportWise, who provides IT services, alongside the management of the devices in which they support.
An MSP can help with desktop and server support, helpdesk operations, network operations and VOIP and hosting solutions.
The ‘Managed’ aspect refers to monitoring, updating, securing and proactively supporting devices such as end user PCs, servers, firewalls, switches and other equipment within their remit.
Most companies with a team would benefit from outsourcing support on some or all of these aspects of your IT infrastructure.
