Arqit and nLighten Demonstrate Sovereign Cloud Data Control in Public Cloud Environments — Arqit Quantum Inc.

Event summary

Arqit and nLighten completed a proof of concept demonstrating how organizations can use public cloud services while maintaining control over sensitive data and cryptographic assets.
The POC was conducted between nLighten's Geneva data center and one of the largest hyperscalers in the world.
Arqit’s Symmetric Key Agreement Platform (SKA-Platform™) extends a trusted environment securely into the cloud, while Intel TDX isolates VMs or containers from unauthorized access.
The solution addresses concerns for regulated organizations in financial services, pharmaceuticals, and the public sector about maintaining sovereignty when sensitive workloads move beyond environments under their direct oversight.

The big picture

The successful POC addresses a growing challenge for regulated industries seeking to balance the advantages of public cloud platforms with the need for data sovereignty. As regulatory scrutiny around digital sovereignty increases across Europe, this joint solution provides a technical assurance-based approach that could set a new standard for secure cloud computing.

What we're watching

Regulatory Compliance: How the joint solution will support organizations in meeting emerging EU Cloud Sovereignty Framework requirements while continuing to benefit from cloud technologies.
Market Expansion: The pace at which the model will be replicated across nLighten's network of more than 30 edge data centers spanning seven European countries.
Technological Integration: Whether organizations can effectively integrate confidential computing and cryptographic controls into their existing cloud environments without compromising innovation.
