Are the robotaxi companies quantum-safe?
Is WeRide quantum-safe?
Partly. 2 of 13 public servers under weride.ai use post-quantum key exchange, the protection against traffic recorded today being decrypted once a large quantum computer exists. Grade C. Scanned October 19, 2026.

What this means
NIST has scheduled the key exchange most servers still use for retirement: deprecated after 2030, disallowed after 2035 (NIST IR 8547). Traffic recorded today can be decrypted once a large quantum computer exists. A server that offers hybrid ML-KEM key exchange closes that today; a server that does not is still open to harvest now, decrypt later.
Hostnames come from public certificate logs plus common service names, kept where the name resolves to a public address, and each is tested from the outside with post-quantum-only TLS 1.3 handshakes. A hostname shows what a server is called, not what traffic it carries; internal systems are out of scope. Method.
