The Quantum Readiness Challenge: Protecting Digital Trust and Preparing for Q-Day

How prepared are organisations for the arrival of quantum computing, and what does it mean for the future of cybersecurity and digital trust?

 

In this episode of CXO Secrets, David McClelland speaks with Arvid Vermote, CISO at GlobalSign, about the growing quantum threat, the reality of Q-Day and why organisations need to start preparing for the post-quantum era now.

 

Arvid explores the risks of harvest now, decrypt later attacks, the importance of post-quantum cryptography and how businesses can build a Cryptographic Bill of Materials (CBOM) to understand their exposure.

 

Topics covered include:

  • The reality of quantum computing and how close we are to Q-Day.
  • The risks of harvest now, decrypt later attacks.
  • Why digital identity, certificates and trust are vulnerable to future quantum threats.
  • Post-quantum cryptography and the role of Merkle Tree Certificates (MTC).
  • Building a Cryptographic Bill of Materials (CBOM) to map organisational exposure.
  • How technology leaders can prioritise quantum readiness and secure board-level investment.
  • Leading through major cybersecurity incidents and protecting your team under pressure.
  • How AI is changing organisational structures and the future of leadership.

 

Arvid also shares his personal leadership philosophy, explaining why a leader should be the first to step forward during a crisis and take responsibility so their team can focus on what matters.
