US-headquartered vendors building the migration off RSA and ECC — PQC libraries and silicon, cryptographic discovery, migration platforms, quantum-safe networking, QKD hardware and quantum entropy. Filter by the control you actually need.
Scope: US-headquartered vendors only. Significant PQC and quantum-safe suppliers based in the UK, Canada, the EU and Asia are out of scope here, so an empty category means no US independent on this map — not no supplier.
Inclusion is not endorsement: this is an independent reference map, not a shortlist, ranking, or investment advice. Funding and founding-year fields are best-effort from public announcements and show as “—” where unverified. Corrections welcome.
