Telsy and Fortinet Collaborate for Quantum-Safe VPN

In the era of quantum computing, where what appears secure today may become vulnerable tomorrow, it is essential to adopt solutions designed for the future.

For this reason, Telsy and Fortinet have established a strategic collaboration: by combining Telsy’s QKD (Quantum Key Distribution) technology with Fortinet’s Next-Generation Firewalls, organizations will be able to rely on a VPN resistant to quantum-related risks.

The integrated solution utilizes Fortinet’s industry-leading products and solutions, and the quantum cryptographic key distribution (QKD) technology developed by Telsy and QTI to enable VPNs capable of countering next-generation cyber threats based on quantum computing. This technology is now integrated with Fortinet’s FortiGate next-generation firewalls, showcasing Italian technological excellence capable of competing globally in strategic innovation sectors.

The solution and context

Quantum technologies are advancing rapidly, creating scenarios in which cryptographic algorithms widely used today could become compromised.

Government communications, critical infrastructure, and organizations with high security requirements all demand a forward-looking approach. The risk is real: if an encryption key can be derived using quantum methods—leveraging the immense computational power of quantum computers—communication confidentiality may be compromised.

The partnership between Telsy and Fortinet brings forth a solution with three core elements:

• Telsy’s “Quell-X” QKD system: an ETSI-compliant system that generates and distributes cryptographic keys via photons in an unconditionally secure way between trusted endpoints
• Fortinet FortiGate NGFW (Next-Generation Firewall): FortiGate NGFWs are designed for flexible deployments across physical, virtualized, and cloud environments with consistent and unmatched network and security performance in a single unified and scalable platform
• Standardized API integration: the “Quell-X” QKD system makes quantum keys available to FortiGate NGFW via ETSI-compliant APIs, which then use the keys to establish highly secure IPsec tunnels

In practice, a quantum channel is established between two nodes (“Alice” and “Bob”). Encryption keys are exchanged through Telsy’s QKD system, and then—via API—the generated key is transferred to the FortiGate NGFW, which uses that secured data to initiate an encrypted VPN tunnel.

The integration between the FortiGate NGFW and Telsy’s technology thus enables the generation and distribution of quantum cryptographic keys and their use to strengthen data confidentiality and integrity over the long term.

The solution is designed for plug-and-play deployment within enterprise and public sector environments where Fortinet technologies are already widely used, accelerating deployment time and reducing integration risks.

Value for the Italian and international market

In a world where regulation, compliance, and data protection requirements are becoming increasingly stringent, offering a quantum-resistant solution is no longer a “nice-to-have,” but rather an emerging strategic necessity.

Telsy, which also operates nationally on critical infrastructure, is in a privileged position to support public institutions, telecommunications operators, and critical enterprises on their secure transformation journey.

Thanks to its synergy with a leader like Fortinet, these capabilities can now be extended to broader enterprise environments, combining agility, high performance, and elevated security.

The future of secure communications requires a proactive vision: the integration of Telsy’s QKD and Fortinet’s FortiGate NGFW provides a solution that not only meets today’s needs, but is also capable of withstanding upcoming quantum threats.

Through this initiative, TIM Enterprise, Telsy, and Fortinet promote a model of integrated, future-proof cybersecurity, where cloud, artificial intelligence, and quantum technologies converge to drive digital transformation and security.
