DISP experiencedDefence obligations change how IT must operate.
Your technology provider needs to understand what your Defence customers expect, not just how to resolve a support ticket.
Technical data, contract security conditions and supply chain requirements create responsibilities for how information is stored, accessed, managed and evidenced. Calexi builds those obligations into day-to-day operations.

What Defence businesses ask us.
Can Calexi replace our existing IT provider?
Yes. We manage a structured transition covering access, systems, documentation and responsibilities to avoid gaps during handover.
Do you manage both IT and cyber security?
Yes. Managed IT and cyber security operate as one coordinated service, with clearly defined responsibilities and escalation pathways.
Can you assist with DISP and Essential Eight?
We implement, maintain and document relevant technical controls. DISP membership decisions remain with the Defence Industry Security Office and formal compliance outcomes remain with the relevant authority or assessor.
What size businesses do you support?
Our managed service model is best suited to small Defence industry businesses, particularly those with around 10 to 60 staff who want a complete outsourced IT function.
