Google's Post-Quantum Upgrade Doesn't Mean We're All Protected Yet

The report discusses the ongoing transition to post-quantum cryptography, noting NIST’s standardization efforts and a joint NSA/CISA/NIST call for quantum-readiness, while spotlighting Google’s addition of the Kyber KEM in Chrome as a hybrid TLS enhancement. It emphasizes that true quantum safety remains distant due to server-side adoption lags, pending IETF standardization, and unprotected back-end links (e.g., data center traffic). With harvest-now-decrypt-later threats already present, the piece advises organizations to develop their own end-to-end, quantum-safe architectures and hybrid cryptographic approaches—alongside updated identity and access practices—rather than waiting for public infrastructure to catch up.
