In the wild.
70+ examples. One primitive. Across industries and data flows.
Polymonial does a lot. These use case examples show how — across the flows your business already runs (a CSV, an API, an EDI feed, a healthcare record exchange etc) and the problems it already faces (proving compliance, sharing data with partners, migrating off legacy crypto etc). Filter by your sector, the data flow you have today, the theme you care about, or the problem you’re trying to solve.

Embedded Device PQC Readiness
Hundreds of millions of embedded devices — smart meters, connected vehicles, medical devices, industrial sensors, payment terminals — were deployed with classical cryptography baked into firmware. NIST has finalised the PQC standards (FIPS 203/204) and the migration runway has started. Polymonial is crypto-agile by design: each device migrates on its own schedule, and yesterday's signed reading still verifies tomorrow.

Manufacturing
Industrial IoT Vendor Telemetry
PLC sensors stream telemetry to vendor clouds for predictive maintenance — and accidentally expose your production secrets.
