About IT Guardian

IT Guardian works with a narrow and clearly stated client profile. It supports internal IT departments managing roughly 100 to 1,000 computers with fewer than five staff, which is exactly the size where a team is too big for ad hoc tools and too small to build its own operations practice.

Rather than supplying bodies, the firm supplies systems. Its delivery includes a virtual CIO function, IT management, network operations, engineering, cybersecurity, regulatory compliance, service management, help desk support and on-site services, together with the RMM platform, helpdesk ticketing and alerting and monitoring stack behind them. The company states plainly that it is not a staffing firm.

Its published alignment covers ITIL and ISO 20000 for service management plus NIST, CMMC and HIPAA on the compliance side, which maps directly onto the defense supply chain and healthcare clusters that define Nashua. IT Guardian shares ownership with CIS Technical Services, which also lists it as the delivery arm for co-managed engagements.
