Google Cloud lays out staged post-quantum migration
🔒 Google Cloud published a staged post-quantum migration roadmap on August 12, splitting work into three risk domains from its quantum threat model. The provider targets mitigating store-now-decrypt-later (SNDL) risks by end of 2027, with signature hardening and key management agility running to end of 2028. Several services already support hybrid NIST-standardized ML-KEM and related primitives, while others (Cloud VPN, Private CA, Cloud HSM) phase in through 2028. Google warns hardware replacement cycles may extend some transitions beyond 2029.
