Conclusion
No organization can afford to treat post‑quantum migration as a future problem to be solved in 2028. Every piece of encrypted traffic captured today is a potential liability —. nation‑state adversaries and well‑funded criminal operations are already harvesting encrypted sessions with. the explicit intent of decrypting them once quantum hardware matures. The “harvest now, decrypt later” attack strategy means that sensitive data encrypted. today with RSA‑2048 or ECC could be open within the operational lifetime of that data’s classification level. For healthcare records, financial transactions, and intellectual property, that lifetime can exceed 20 years. The window between now and when quantum‑safe cryptography becomes mandatory is the. period of maximum risk — and it closes faster than most organizations. realize.
