Sopra Steria, one of Europe’s leading technology providers, has enhanced its Datasphere data-centric security platform by embedding hybrid post-quantum cryptography. This upgrade brings together advanced data labeling, attribute-based access control, and next-generation quantum-resistant encryption to strengthen the protection of sensitive information against emerging cyber risks.

The move represents a significant step in safeguarding critical data at a time when the rapid rise of quantum computing is reshaping the cybersecurity landscape. Conventional cryptographic methods, long relied upon for data confidentiality and integrity, are expected to lose effectiveness as quantum capabilities expand. In response, the adoption of post-quantum encryption has become essential for organizations handling sensitive information.
