Why CIOs must pivot to post-quantum cryptography now

Post-quantum cryptography is shifting from a long-range research topic to an urgent enterprise risk issue, because encrypted data captured today may be exposed later by quantum-capable attackers. For CIOs, the business impact is significant: protecting long-lived sensitive data, avoiding future compliance and reputational fallout, and modernizing cryptographic infrastructure will require crypto-agility, hybrid migration strategies, and close attention to performance in high-throughput environments. IT organizations should treat this as a cross-platform architecture program, not a simple security patch, and begin inventorying cryptographic dependencies across apps, infrastructure, and third-party services now.
