PQC gateway pattern
qREK at the IT/OT boundary terminates legacy crypto and re-wraps in PQC.
Industry · OT.04
Critical Infrastructure
Quantum resilience across grids, pipelines, water, and transport.
Bring PQC to operational technology environments where uptime is non-negotiable and the cryptographic estate spans decades of vendors.
The challenge
What we hear from critical infrastructure leaders.
Long-lived OT devices with no native PQC support
IT/OT convergence widening the cryptographic attack surface
IEC 62443 and NIS2 obligations on rapid timelines
Our approach
How we deploy.
Operator identity
QAuth for workforce, contractor, and machine access across plants.
Sovereign telemetry
Encrypted, jurisdictionally bounded telemetry pipelines via QSE Storage.
