Thierry Lempereur from Sopra Steria announced the integration of hybrid post‑quantum encryption technology into Datasphere, the company’s data‑centric security solution. The new layer combines classical cryptographic algorithms with quantum‑resistant primitives, thereby ensuring sustainable protection of sensitive data against future threats while maintaining compliance with NIST recommendations for hybrid post‑quantum schemes and interoperability with NATO and other international security standards. This development represents a decisive step forward for organisations in the defence, industrial and civil sectors, allowing them to continue using existing infrastructures while preparing for the inevitable arrival of quantum‑powered attacks.
Sopra Steria Integrates Hybrid Post Quantum Encryption into Datasphere
On 9 September 2025 in Paris, Sopra Steria announced that its Datasphere platform now incorporates hybrid post‑quantum cryptography at its core, blending conventional cryptographic algorithms with quantum‑resistant primitives to deliver a continuous, quantum‑proof protection regime that can be applied directly to documents and data within familiar office suites such as Microsoft Office.
The update satisfies the latest National Institute of Standards and Technology (NIST) guidance on transitioning to post‑quantum encryption schemes and aligns with NATO’s security standards. Datasphere’s architecture couples data labelling, attribute‑based access control and the new quantum‑resistant algorithms, enabling organisations to maintain existing infrastructure while preparing for the inevitable arrival of quantum computing. The solution offers a pragmatic, interoperable pathway to long‑term data security, with a flexible transition period that allows users to continue operating with current systems while gradually integrating the new cryptographic layer and reinforcing digital sovereignty across civil, industrial and defence sectors.
Thierry Lempereur, Director of Defence & Security at Sopra Steria, said the integration “anticipates tomorrow’s threats today” and positions the company as a strategic partner for entities that must safeguard critical information against future cyber risks. Datasphere is already adopted across civil, industrial and defence organisations, underscoring a broader industry trend toward proactive adaptation to quantum threats.
