Quantum Readiness Gap: True Crypto-Agility Defined

Enterprises are currently adopting post-quantum security measures at varying speeds, leading to a noticeable disparity among organizations. A significant gap is emerging between companies that have genuinely integrated crypto-agility into their infrastructure and those that merely claim the term without possessing the underlying capabilities. Dr. Tan Teik Guan, CEO of pQCee, a Singapore-based cybersecurity firm, emphasizes this distinction. He defines true crypto-agility as going beyond the mere support for multiple algorithms or protocol-level negotiation. Instead, it necessitates the robust ability to deploy appropriate cryptographic defenses dynamically and effectively. This fragmentation in defense response occurs even as quantum threats are already considered active, highlighting the urgent need for genuine cryptographic resilience.
