Google Cloud Targets 2027 for First Post-Quantum Security Milestone

What happened

Google Cloud announced in August that it aims to complete mitigating store-now-decrypt-later (SNDL) risks in its first major risk domain by the end of 2027. The company has already deployed quantum-safe key exchange using NIST-standardized ML-KEM in hybrid mode across Cloud API endpoints.

Why it matters

This addresses the 'store-now-decrypt-later' threat where data harvested today could be decrypted by future quantum computers. Google notes that while software timelines may reach 2027, hardware upgrades for physical components could extend beyond 2029 depending on replacement cycles.
