The service, called Quantum Shield, is available as an additional security layer on euNetworks' Private Connect MOFN product, which provides dedicated fibre-based managed connectivity. The new layer adds quantum-resistant encryption at Layer 1 — meaning traffic is encrypted at the optical transport level before it reaches higher networking layers — alongside continuous fibre monitoring that can detect and locate physical tapping events in real time.
The technical foundation is Adtran's FSP 3000 optical transport platform with S-Flex™ technology for high-capacity encrypted data-centre interconnect services. Post-quantum cryptography follows NIST standards, and the cryptographic design is described as crypto-agile: built for current requirements but structured to track emerging standards as they develop.
euNetworks operates a pan-European network that directly connects more than 600 data centres across 18 metropolitan networks in 53 cities and 17 countries. The launch lands as DORA and NIS2 regulations increase expectations on encryption and crypto-agility for operators handling regulated workloads, and as the EU's coordinated PQC roadmap formally targets migration of critical environments by 2030.
Data centre connectivity sits at the heart of our customers' operations, particularly in environments where security and resilience are non-negotiable
Operators like euNetworks are setting a clear benchmark for how secure data centre connectivity should be delivered
Quantum Shield is available to customers now. euNetworks is headquartered in London and carries services across its pan-European backbone.
