LONDON, UK – October 3, 2024 : Defence Holdings PLC (LSE: ALRT), a leading UK software-led defence company, today announced it has selected Google Cloud as its hyperscale provider for Project Ixian. This initiative marks the company’s inaugural sovereign AI product, developed under its Defence Technologies division, and is focused on enhancing information integrity and resilience against information warfare.

Project Ixian will be built natively on Google Distributed Cloud air-gapped, a platform specifically designed for the most stringent data residency, security controls, and operates fully disconnected from the internet.
 

"Information has become critical infrastructure, and its protection is paramount," said Andy McCartney, Chief Technology Officer of Defence Holdings. "By selecting Google Cloud, we are establishing sovereign AI capability on the same technology, aligned with UK Government investments. Project Ixian exemplifies how infrastructure translates into capability – sovereign by design, scalable from inception, and directly addressing one of the most urgent areas of focus of our time: information operations. Project Ixian is just the first in a multi-product pipeline we intend to bring from concept to operational use over the next 18 months."

Project Ixian is specifically designed to address critical focus areas of the UK’s Strategic Defence Review 2025 (SDR25), countering challenges such as disinformation, digital vulnerabilities, and narrative manipulation by malicious actors. Its development has been deeply informed by Defence end-users and includes co-development with Whitespace engineers to embed sovereign standards, resilience, scalability, and compliance from inception.

John Abel, UK Managing Director, Office of the CTO, Google Cloud , commented: "This initiative brings together our sovereign infrastructure with Defence Holdings’ focus, ensuring that the UK can benefit from technologies that are both operationally relevant and sovereign by design."
