# NATO Selects Quantum-Safe Networking Consortium

Arqit and Sirius Computer have been selected as part of a winning consortium for a NATO secure-networking framework. Arqit also made an undisclosed strategic investment in Sirius to advance the Crux tactical communications platform, combining Sirius’s networking technology with Arqit’s quantum-safe encryption. The framework has a one-year base period and two annual renewal options, but no contract value, solicitation number, procurement schedule, or contact was provided. The companies are pursuing additional opportunities with the UK Ministry of Defence and U.S. Department of Defense, making this a consortium and technology-pipeline signal rather than a published open solicitation.

- The NATO framework is the identified procurement opportunity; its value and the consortium’s specific scope or work allocation are not stated.
- The investment is intended to support engineering and hardware-acceleration work in the United States, United Kingdom, and Germany. Secure-networking, encryption, and integration firms may find potential teaming relevance as the platform develops.
- Companies evaluating this market should distinguish the NATO selection from the separate UK MoD and U.S. DoD pursuits; the signals provide no solicitation details or schedule for those pursuits.
