Cloud-delivered quantum entropy works for most organisations. But some environments demand absolute sovereignty over their cryptographic material. Defence agencies operating in classified networks. Financial institutions with co-location mandates. Telecom operators building 5G core infrastructure. Certificate authorities issuing millions of certificates daily. For these operators, entropy must be generated locally, consumed locally, and never traverse a network boundary.

The QCoreSecure Appliance houses our powerful silicon-photonics QRNG chip in a compact, rack-mountable enclosure. It generates NIST SP 800-90B certified quantum entropy at >200 Mbps - continuously, locally, with zero network dependency. The appliance connects directly to your HSM clusters, key management systems, certificate authorities, and network security infrastructure via Ethernet, USB, or SFP+ interfaces.

Deploy the appliance in your data centre, SCIF, or secure facility. Connect it to your cryptographic infrastructure using standard interfaces and the provided SDKs for C/C++, Python, or Java. The appliance runs continuous NIST SP 800-90B health tests on every entropy block in real time. If any anomaly is detected, output halts until validation is restored - the same zero-compromise approach as our cloud platform, running entirely on your hardware.
