Cross Domain System Specialists

Designing Next-Gen National Security Applications using the CDHA Framework

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.

 

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.

At a Glance:

  • All staff hold SC/DV level National Security Vetting

  • Deep-tech team with real-world defence project experience

  • Active collaborations with UK Government, Defence Primes and Academia

Upcoming Events

We’re excited to be exhibiting at CYBERUK 2026, returning to Glasgow from 21–23 April for the UK government’s flagship cyber security event — and a special year as NCSC marks its 10th anniversary. This milestone edition, themed “The Next Decade: Accelerating Our Cyber Defence”, is set to be one of the most impactful yet.

If you’re attending, come and meet the team on Stand C6, where we’ll be showcasing our Cross Domain Hybrid Application (CDHA) framework.

We looking forward to seeing you!
