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.

Finance
Multi-Jurisdiction Compliance
One dataset. Many regulators. Each gets their proof — no data crosses any border.
EXA15
PublicSector
Sovereign Training Data Provenance
Prove your sovereign model was trained on cleared, in-country data — without revealing the corpus.
EXA25
Utilities
Smart Metering
Accurate billing without revealing when you're home, when you wake, when you leave.
EXA26
Insurance
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.

Utilities
Smart-Meter Telemetry
Smart-meter telemetry crosses utility brokers, ISP backbones, and third-party aggregators in plaintext. Polymonial seals each message so the granular pattern never leaves the meter.

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.
EXA57
Universal
Mobile App Telemetry
Your app uploads everything the user touches — Polymonial seals events so the backend gets analytics, not behavioural fingerprints.

Cross-Border Data Transfer
Schrems II says assume hostile foreign surveillance — Polymonial says the surveiller finds nothing usable.
EXA70
Healthcare
Confidential Diagnostics
Run the diagnostic model in the browser — the patient scan never leaves the device.
EXA71
Logistics
Aviation Data Authenticity
Prove a data feed is genuine and unaltered — from the source, not the middleman.
