Adtran and euNetworks launch quantum-safe connectivity service

Adtran and euNetworks unveil Quantum Shield, a quantum-safe private connectivity service aiming to enhance data centre connectivity across Europe.

Adtran and euNetworks have announced the introduction of Quantum Shield, a quantum-safe private connectivity service. Built using Adtran’s optical transport technology, the offering is part of euNetworks’ pan-European network and is designed to support secure and scalable data centre connectivity.

The service is intended for organisations with requirements for security, performance and customer-controlled encryption. It combines high-capacity infrastructure with real-time fibre monitoring to improve optical-layer visibility and support the protection of data traffic. The integration aims to provide encryption and continuous monitoring for data transmitted across Europe.

The announcement comes as European organisations respond to evolving cybersecurity regulations and the EU's post-quantum security guidance. European Union directives, including DORA and NIS2, introduce increased requirements for encryption and the protection of traffic across infrastructure.

Quantum Shield is available as an additional security layer within euNetworks’ Private Connect MOFN solution, providing quantum-safe connectivity over private fibre networks. The service incorporates quantum-resistant encryption at Layer 1, enabling automatic encryption of all traffic.

The infrastructure is based on Adtran’s FSP 3000 optical transport platform and S-Flex technology, which support high-capacity encrypted Data Centre Interconnect (DCI) services. It uses post-quantum cryptography aligned with NIST standards to protect traffic across optical infrastructure. The cryptography is designed to align with current and emerging standards and supports a crypto-agile approach.

Adtran’s ALM solution provides continuous monitoring of the optical network, including the detection of fibre-tapping events. Combined with the encryption capabilities, the technologies are intended to support low-latency, high-throughput optical connectivity while providing customers with greater visibility and control over their data.

As demand for secure and resilient data centre connectivity continues to grow, the service is intended to address organisations seeking quantum-safe encryption and enhanced monitoring for private optical networks.
