Quantum computers are on the horizon, but your confidential data must stay private for decades. Orange Quantum Defender merges Quantum Key Distribution (QKD) with Post-Quantum Cryptography (PQC) to deliver immediate and future-proof security.
The quantum threat has already begun
Public-key algorithms that safeguard today’s internet will collapse once large-scale and super powerful quantum computers arrive. Adversaries are already storing your data now to decrypt later, exposing finance, government and critical-infrastructure data to long-term compromise.
A French first: Orange Quantum Defender
On 11 June 2025, Orange Business and Toshiba Europe launched Orange Quantum Defender, the first commercial quantum-secure network service in France. the service unites:
- QKD – hardware that generates and distributes encryption keys using the laws of quantum physics, making eavesdropping instantly detectable.
- PQC – software algorithms endorsed by NIST to resist quantum attacks, ensuring resilience and agility.

“We are thrilled to launch Orange Quantum Defender – a first-of-its-kind service in France. This is a significant step in the Orange multi-layer quantum-safe networking strategy, as we help our enterprise customers respond to the growing and evolving security threats from quantum computing.”
Aliette Mousnier-Lompré, CEO of Orange Business
Why multilayer security matters
Challenge | Benefit with Orange Quantum Defender |
---|---|
“Store Now, Decrypt it Later” attacks | Dual protection: physics-based key exchange plus quantum-resistant algorithms |
Need to evolve without ripping out networks | Seamless overlay on existing fibre; software layer updated as standards evolve |
Long retention obligations | Keys generated by quantum physics; algorithms future-proofed for decades |
Secure the next decade—today
Quantum attacks are a when, not an if. Orange Quantum Defender equips you with the strongest commercially available defence so you can innovate with confidence.
