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.

Accurate billing without revealing when you're home, when you wake, when you leave.

Connected Vehicles
Telematics + V2V data flows under UN R155 / R156, AUTOSAR PKI, IEEE 1609 — Polymonial seals at the ECU so safe-driving proofs reach insurers without the full route, time, or behavioural pattern.
EXA27
Utilities
Critical Infrastructure Telemetry
Telemetry over IEC 61850 / DNP3 sealed at the device. NIS2 + IEC 62443 zone/conduit objectives met without the grid map ever leaving the operator's perimeter.

Media Provenance
C2PA content credentials + JPEG Trust + W3C Verifiable Credentials — Polymonial seals the sensor-to-broadcast chain so authentic footage carries an unforgeable lineage and deepfakes don't.

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.
EXA46
Manufacturing
Industrial IoT Vendor Telemetry
PLC sensors stream telemetry to vendor clouds for predictive maintenance — and accidentally expose your production secrets.
EXA49
Universal
OAuth Identity Token Slimming
Single sign-on tokens leak the full user profile to every relying party — Polymonial wraps the assertion so only requested claims decrypt.
