An IT firm with no Google reviews scores zero on rating, review volume and recency; other factors we cannot measure are left out.

Yes, if they are within 50 mi of the Castle Rock city center, our service radius for managed IT service providers. Each listing shows where the IT firm is based and how far away it is. Proximity is 5% of the IFR Score, so a nearby IT firm gets a small edge.
Can managed IT service providers pay to rank higher on ITFirmsRanked?
No. The IFR Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured IT firms may appear above the list, labelled Sponsored and showing their honest rank.
What does a managed IT service provider do?
Managed IT service providers (MSPs) run a business’s computers, servers, network, Microsoft 365 or Google accounts, backups and help desk for a monthly fee, or provide IT support by the hour.
How are managed it service providers in Castle Rock ranked?
By IFR Score: Google rating and review volume, recent reviews, opening hours, how clearly the firm does managed IT services and IT support, distance, a claimed profile, our badge and verified client reviews. Sponsored placements never change the order.
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.
How long are managed IT contracts?
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.
