Demand for trusted and resilient communications is growing rapidly as organisations seek to protect critical data against emerging cyber threats. While Quantum Key Distribution (QKD) offers a path to future-proof security, uncertainty around integration, performance, cost and operational risk can make investment decisions challenging.
The Craft Prospect QKD Space Network Emulator is designed to help organisations evaluate quantum-secure communications in a realistic operational environment. By emulating key elements of a space-enabled QKD network, it supports service validation, stakeholder engagement and technology assessment before deployment.
This approach enables organisations to validate business cases, assess network integration, reduce deployment risk, and build confidence in service readiness, accelerating the path from concept to operational capability.
