Managed ICT Systems Administration for Government and Business

Calexi provides Managed IT Services for organisations that need reliable operations, controlled change, and defensible security outcomes. We operate across Windows, Linux, Microsoft 365, cloud, on-prem and hybrid environments with a focus on availability, repeatability, and assurance.

If you need a Managed Service Provider (MSP) that can handle day-to-day IT operations and security uplift without drama, we’ll stabilise your environment, document it properly, and keep it running.
