infrastructure such as VPNs and hardware security modules to automate key generation, distribution, and rotation. Quantumspace also builds compact satellite QKD transmitter modules, optical ground stations, laser communication terminals, and PQC modules to harden classical links. These products are intended for governments, enterprises, financial institutions, telecom operators, and operators of critical infrastructure that require long-term protection of sensitive communications. Solutions are designed to plug into current networks while enabling a migration path toward future quantum-secure architectures.
