Post-Quantum

Post-Quantum is a quantum-safe cybersecurity company founded in 2009 that protects critical infrastructure against both present-day threats and future quantum-computing attacks. Its platform spans Identity Protection, a hybrid post-quantum VPN standardized by the IETF as RFC 9370, and quantum-safe messaging, built on a crypto-agile modular architecture and NIST-round cryptography such as Classic McEliece. The company authored RFC 9370, delivered first-in-world quantum-safe drone communications, and its technology is deployed in NATO and active defense environments. The public web presence is a marketing and platform-overview site; no public developer API, SDK, documentation portal, or sign-up surface is published as of this enrichment pass.

Post-Quantum is profiled on the APIs.io network. Tagged areas include Company, Security, Cybersecurity, Quantum, and Post-Quantum Cryptography.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/post-quantum: open an issue to ask a question, or submit a pull request to add artifacts.
