In this episode, we sit down with Marco Pereira, Executive Vice President and Global Head of Cybersecurity at Capgemini, as he explores the looming risk posed by quantum computing to current encryption standards. Marco breaks down what could happen the day encryption breaks—referred to as “Q Day”—and highlights why the urgency to prepare for quantum threats is so critical, especially given the uncertainty about when this shift might occur. He discusses the widespread reliance on RSA-based encryption, the potential for a sudden cyber ‘Armageddon’ if organisations are not proactive, and the immense challenge of transitioning global digital infrastructure to post-quantum cryptography. Marco also addresses the current lack of urgency and crypto expertise in the industry, emphasises the need for crypto agility, and draws parallels to the rapid adoption challenges seen with cloud computing and AI. Marco is an industry-recognised cybersecurity thought leader and strategist with over 25 years of leadership and hands-on experience. He has a proven track record of successfully implementing highly complex, large-scale IT transformation projects. Known for his visionary approach, Marco has been instrumental in shaping and executing numerous strategic cybersecurity initiatives. Marco holds a master’s degree in information systems and computer engineering, as well as a Master of Business Administration (MBA). His unique blend of technical expertise and business acumen enables him to bridge the gap between technology and strategy, driving innovation and achieving organisational goals.
