About Us
What We Do
At Acubed IT, we design and build solutions that enable interoperability across air-gapped classification boundaries using our Cross Domain Hybrid Application (CDHA) framework and advanced cryptography expertise.
We specialise in cross-domain integration, helping Government, Defence, and Critical National Infrastructure share information safely across security boundaries. Our unique approach ensures applications can seamlessly span security domains while keeping sensitive data protected at its most vulnerable—at OFFICIAL—using cryptography-based controls.
We integrate High Assurance Gateway (HAG) technology into our systems through trusted partner and reseller agreements. As gateway-agnostic integrators, we work with multiple HAG providers to deliver the best-fit solution for each use case.
