The locksmiths finished. Most organizations have not started changing the locks 🔓 The quantum migration is not blocked by missing cryptography. NIST standards are final. Quantum-safe signatures exist. Hybrid key exchanges are already protecting a large share of real-world TLS traffic. The new locks are standardized and on the shelf The hard work is operational and unglamorous: 📝 Inventory every cryptographic dependency. 🔍 Find every system, certificate, and long-lived data store that will outlive its current protections Replace, test, and build the ability to replace again without redesigning the whole estate Crypto-agility is the lasting outcome. Waiting for a clearer “Q-Day” simply shortens the window for orderly change Next week: why some of those locks must move considerably faster than others. Keys and long-lived secrets run on two very different clocks #PostQuantum #PQC
