Orange Business and Toshiba Digital Solutions have jointly launched the first commercial quantum-safe network service in France, combining quantum key distribution (QKD) with post-quantum cryptography (PQC). The solution, called Orange Quantum Defender, is now available to enterprise customers in the greater Paris area and is already securing critical data for a major French financial services firm.
The system leverages Toshiba’s QKD technology across Orange’s commercial fiber infrastructure, integrating a defense-in-depth strategy that pairs hardware-based quantum key exchange with software-based cryptographic algorithms resistant to quantum attacks. This architecture addresses the growing threat of “store now, decrypt later” tactics, in which sensitive data is exfiltrated today and held for future decryption by quantum computers. The multi-layered approach is designed to provide long-term confidentiality for sectors including finance, public infrastructure, and healthcare.
The launch follows years of collaborative testing between the two companies. Previous joint demonstrations validated the scalability and performance of Toshiba’s QKD across conventional fiber networks, showing that high secret key rates could be maintained over long distances and in co-existence with classical data signals. The new offering also contributes to France’s broader national quantum strategy, positioning Orange as a leading operator of quantum-resilient infrastructure.
