Adtran’s encrypted optical transport technology is helping euNetworks deliver the highest levels of protection for sensitive data moving across Europe.
News summary:
Developed by euNetworks to deliver the highest levels of protection for sensitive data moving between European data centers
Built on Adtran’s solution, euNetworks’ new Quantum Shield service enables quantum-safe encryption across private high-capacity connectivity, with continuous optical and fiber plant monitoring
The new offering supports regulated industries with strong assurance against current and emerging cybersecurity threats
LONDON, May 27, 2026–(BUSINESS WIRE)–Adtran and euNetworks today announced their collaboration on the launch of a new quantum-safe private connectivity service, Quantum Shield. euNetworks has developed Quantum Shield using Adtran’s optical transport technology to augment its broader architecture, which is designed to deliver secure, scalable data center connectivity across euNetworks’ pan-European network.
The new offering is built for enterprises with stringent security, performance and customer-controlled encryption requirements. The deployment combines high-capacity dedicated infrastructure with real-time fiber monitoring and enhanced optical-layer visibility to safeguard critical traffic. By integrating advanced encryption with continuous monitoring across the optical layer, euNetworks can deliver the highest levels of protection for sensitive data moving across Europe.
This comes at a time when organizations across Europe are accelerating plans to secure data in transit in response to evolving cybersecurity regulations and post-quantum security guidance. The EU’s coordinated post-quantum cryptography roadmap* targets migration of high-risk and critical infrastructure environments by 2030, while regulations, including DORA and NIS2, are increasing expectations for encryption, crypto-agility and the protection of sensitive traffic traversing private and third-party infrastructure.
euNetworks will offer Quantum Shield to customers as an additional security layer for their Private Connect MOFN solution, which provides private, managed network infrastructure for organizations seeking enhanced security, scalability and control over their data. The addition of private quantum-safe connectivity provides the security of the organization’s dedicated fiber, plus quantum-resistant encryption at Layer 1, ensuring all traffic is automatically encrypted.
The new infrastructure is built on Adtran’s FSP 3000 optical transport platform, incorporating S-Flex™ technology to support high-capacity encrypted DCI services. euNetworks is harnessing post-quantum cryptography aligned with NIST standards to protect traffic traversing dedicated optical infrastructure. The cryptography is designed to meet current requirements while remaining aligned with emerging cybersecurity standards, supporting a crypto-agile approach as requirements evolve.
