Arqit announces strategic investment in Sirius to strengthen quantum-safe communications for defence and government

Paul Feenan, General Manager for Defence & Government at Arqit

“Defence organisations face a difficult balance between getting critical information to the people and platforms that need it, while keeping it out of adversaries’ hands. When forces operate alongside allies, that challenge extends across national boundaries and different technologies. Security needs to support that cooperation without adding complexity for personnel on the ground. It also needs to protect information whose sensitivity will outlast the operation itself. Investing in Sirius will help us build on our existing partnership to make quantum-safe communications easier to deploy and extend to more defence users.”

Jason Van der Schyff, Co-Founder and Chief Executive Officer of Sirius

“We've built Sirius around the belief that secure communications shouldn't depend on complex, expensive infrastructure that is difficult to deploy and maintain. Our partnership with Arqit has already demonstrated what's possible when advanced encryption enhances lightweight, adaptable networking technology. This investment is a significant vote of confidence in our team and our technology, and gives us the resources to accelerate development, expand our capabilities and bring these solutions to more defence and government customers around the world.”
