enQase QMesh distributes quantum-derived symmetric key material to Palo Alto Networks Next-Generation Firewalls (NGFW) over the ETSI GS QKD 014 interface. Your existing security architecture stays as it is. What changes is that a physics-based layer of key protection sits underneath it, independent of traditional key exchange.

Hub and spoke
Several sites keyed from a central receiver, for concentrated campus or data centre estates.
Trusted node
Reach extended past a single fibre span by relaying key material through a trusted intermediate node.
Multi-hop
Metro and wide area key distribution networks spanning many sites under one orchestrated fabric.
