Database of Quantum Security Companies (2025)
This living catalog maps the quantum‑security landscape end‑to‑end: post‑quantum cryptography (PQC) vendors (crypto libraries, TLS/QUIC/IPsec/SSH, code‑signing, PKI/CA, HSM/KMS integrations, crypto‑agility orchestration), quantum cryptography (QKD over fiber/satellite, DV/CV stacks, network gear and managed services), QRNG (chips, modules, cloud entropy), as well as consulting, testing, and compliance specialists who deliver migrations, audits, and training.
The goal is practical discovery: who builds what, how it deploys (SDK/appliance/managed service), where it fits (datacenter, cloud, edge, telco), and which standards it aligns to.
How to use it. Filter by capability (PQC library vs. crypto‑agility platform vs. PKI/CA vs. QKD/QRNG), integration target (TLS, QUIC, X.509/PKI, IPsec/SD‑WAN, HSM/KMS, code‑signing), deployment model (SDK, hardware module, appliance, managed service), standards/compliance (FIPS 203/204/205, FIPS 140‑3, IETF drafts, ETSI QKD, ISO/IEC), sector focus (gov/defense, finance, telco, industrial/OT), geography/regulatory, and maturity (research → pilots → production).
Notes & caveats. Real‑world categories overlap – many firms span multiple layers. Where that happens, I tag the dominant role to keep the directory readable. The taxonomy is my own attempt to bring order to a fast‑moving space – not a standard.
This database is under development; entries may change without notice. No warranties: I aim to keep it current, but updates aren’t guaranteed. Feedback and corrections are very welcome.
