Building a practical path to post-quantum cryptography

Quantum computing threatens to break current cryptography, but post-quantum cryptography (PQC) is a manageable evolution, not a crisis. The mathematics behind today’s encrypted digital transactions is vulnerable to quantum attacks. Business leaders must prepare by transitioning to PQC standards, which are being developed as a practical, step-by-step process. This shift is necessary to secure data against future quantum decryption, but it does not require immediate panic. Instead, organizations should begin assessing their cryptographic inventories and planning migration timelines now, as the transition will take years. The path forward involves updating software, hardware, and protocols to withstand quantum threats—a challenge, but a solvable one.
