Quantum-Safe Security
QKD transceiver, QRNG entropy and Q-KMS key management deliver provably secure keys.
Quantum-safe security for critical infrastructure
QUANSHIELD™ combines QKD, post-quantum cryptography and edge threat detection in rugged gateways for grid, telecom, finance, space and defence deployments.

The threat
The quantum threat isn't the future. It's harvest now, decrypt later.
Adversaries are recording encrypted traffic today, including grid telemetry, financial transactions and defence comms, to decrypt when cryptographically relevant quantum computers arrive. The data you send now has a shelf life measured in decades.
- Classical public-key crypto (RSA/ECC) breaks under Shor's algorithm.
- OT and critical infrastructure run on long-lived, hard-to-patch systems.
- Migration deadlines are arriving, and quantum-readiness is becoming a mandate.
What's at stake
A single compromised substation gateway, satellite link or core-banking channel can cascade into national-scale disruption. Bolt-on encryption is not enough; the cryptographic foundation itself must change.
Quanshium closes that window now by combining quantum key distribution with NIST post-quantum cryptography so your infrastructure is protected against both today's and tomorrow's adversaries.
The flagship
One gateway. Quantum security, post-quantum crypto, and edge AI.
QUANSHIELD™ is a rugged security gateway that secures communications, hardens endpoints and detects threats at the edge.
Post-Quantum Crypto
NIST-standard ML-KEM & ML-DSA in a hardware crypto accelerator with secure boot.
Edge AI Threat Detection
On-device NPU runs anomaly detection and predictive analytics without a cloud round-trip.
Rugged & Industrial
Fanless, -40 to +85 °C, IP65/67, with IEC-61850, Modbus, DNP3 and OPC-UA.

How it works
Hybrid QKD and post-quantum key flow
A hybrid QKD + post-quantum flow that never leaves a gap: quantum keys when the link allows, post-quantum cryptography always.
Generate
QRNG seeds true entropy; the QKD transceiver establishes quantum keys over fibre or free-space.
Fallback
Where QKD is unavailable, ML-KEM post-quantum keys are negotiated so protection does not drop.
Enforce
Q-KMS manages keys; secure boot, TPM 2.0 and ML-DSA signatures verify every component.
Detect
Edge AI monitors traffic and OT behaviour, flagging anomalies and acting in real time.
Defence portfolio
Electronic warfare, drones and secure comms
Beyond QUANSHIELD, Quanshium develops indigenous systems for national security programmes.
- Electronic warfare: SIGINT, jamming and spectrum control.
- Drone systems: autonomous platforms for ISR and logistics.
- Counter-drone: detection, tracking and neutralisation.
Defence & national security
