Enterprises are moving toward post-quantum security at uneven speeds, and the gap between organizations that have built crypto-agility into their infrastructure and those that have adopted the label without the underlying capability is widening.

Dr. Tan Teik Guan, CEO of Singapore-based cybersecurity company pQCee, draws a sharp line between the two. Crypto-agility, in his view, requires more than support for multiple algorithms or protocol-level negotiation. It demands the ability to respond with appropriate cryptographic defenses in a cost-effective, timely, and non-disruptive way. That means intelligence, governance, and mitigation working together across a layered defense architecture to maintain a quantum-safe…
