Applications of Tessera.
Tessera protects site-to-site traffic for critical-infrastructure operators across five sectors.
Energy & SCADA
Substation-to-control-centre links carry commands that must stay authentic and topologies that must stay secret for decades. Tessera protects them beside the existing edge, with no change to the control network. Deployment is sequenced around a single short cutover per site.
Healthcare
Patient records outlive every current encryption standard. Multi-site hospital networks connect through Tessera in days, and traffic recorded today stays computationally infeasible to decrypt later. Existing clinical systems are untouched.
Defense
Field encryption with strict compliance requirements and the highest security context. Tessera pairs continuous hardware attestation with vendor-blind key agreement: no one outside the deployment, including Quantasphere, can read the traffic.
Banking & Finance
Inter-bank settlement and clearing traffic crosses organizational boundaries. Tessera pairs institutions securely because the broker holds no secrets. Each side keeps its keys on its own hardware.
Government
Government networks face the earliest quantum-safe procurement mandates. Tessera deploys onto the networks already in place, and a sovereign on-premise tier keeps every component under national control.
