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.

Trade Finance
Prove every clause of a letter of credit is satisfied — without exposing the trade.
EXA11
Healthcare
Clinical Trials & Personalised Medicine
Combine trial results across hospitals worldwide — without a single patient record crossing a border.
EXA12
Healthcare
Encrypted Medical Records
Encrypt every patient record once. Doctors see only what they need — enforced by maths, not policy.
EXA17
Healthcare
Federated Hospital Analytics
Aggregate clinical statistics across hospitals — without sharing a single patient record.
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.

Threat Intelligence Sharing
Sector ISACs exchange STIX 2.1 indicators over TAXII 2.1 — Polymonial wraps the bundle so cross-correlation runs across every member without exposing any single contributor's customer list, network map, or detection method.

Bitcoin Wallet Protection
Migrate your Bitcoin to quantum-safe cryptography — no hard fork, no new address, no protocol change.
EXA31
Universal
Certificate Migration
Move 10,000 TLS certificates to post-quantum cryptography without re-issuing through every CA. Code unchanged.
EXA33
Universal
Cross-Chain Bridge
Move value between blockchains with cryptographic proof — not validator trust.

Federated BI
Self-service BI tools today connect directly to the warehouse and see raw rows — Polymonial wraps the OData feed so analysts get aggregates, not row access.

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.

Customer Support Ticket Privacy
Customers paste credentials into support tickets — Polymonial detects and seals before tier-1 sees them.
