What Are the Challenges of PQC Readiness in Cybersecurity?
Post-Quantum Cryptography (PQC) is quickly becoming one of the most important long-term priorities in cybersecurity. As quantum computing advances, organizations are under pressure to prepare for a future where traditional cryptographic systems may no longer provide adequate protection. The urgency is not only about future quantum attacks. It is also about the complexity of transitioning existing infrastructure, protecting long-lived sensitive data, and managing uncertainty while standards and technologies continue to evolve. For many organizations, PQC readiness is far more complicated than replacing one encryption algorithm with another. It is a large-scale transformation that affects architecture, governance, vendors, operations, compliance, and business continuity. This guide explores the major challenges organizations face when preparing for PQC adoption. Why PQC Readiness Is Difficult Most enterprise environments have built cryptography into systems over decades...
