Why CIOs must pivot to post-quantum cryptography now

The digital bedrock of the modern enterprise—the encryption that secures every financial transaction, medical record, and state secret—is approaching an expiration date.

For today’s CIO, post-quantum cryptography (PQC) is no longer a futuristic research project; it is a critical pillar of contemporary risk management and infrastructure resilience.
