What does a managed IT service provider do?

What should a managed IT agreement include?
At minimum: help desk support for your staff, monitoring and patching of computers and servers, backups that are tested, security tools such as endpoint protection and multi-factor authentication, and a named contact. The agreement should state response times, support hours and what counts as out of scope.
Is managed IT priced per user or per device?
Both models are common, and some firms sell tiered bundles. Per-user pricing suits staff with several devices; per-device pricing suits shared computers. Compare quotes on the same number of users, devices and servers.

Often one to three years, sometimes month to month. Check the notice period, any early-termination fee and how the firm hands over passwords, documentation and data when the contract ends.
