About Us

What We Do

At Acubed IT, we design and build solutions that enable secure interoperability across air-gapped classification boundaries using XD-CORE® CDHA Platform and advanced cryptography expertise.

We specialise in cross domain solution 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.

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.
