Quantum Encryption Deadline Forces Real Infrastructure Overhaul

Organizations are shifting from planning documents to actual implementation as 2029 approaches—the year when sufficiently advanced quantum computers could theoretically crack today's encryption standards, forcing a race to adopt quantum-resistant algorithms across banking, government, and critical infrastructure. The National Institute of Standards and Technology has finalized post-quantum cryptography standards, vendors are shipping products, and enterprises face genuine costs and complexity in retrofitting systems that were never designed for mid-lifecycle cryptographic migration. Adversaries are already harvesting encrypted data today with the intention of decrypting it once quantum capabilities mature, compressing the window for transition.
