What does running 68 kilometres through snow at night teach you about business, risk, and resilience?
For Mathew Breuillac, it’s everything. A former chemical engineer turned cybersecurity leader, Mathew has spent his career at the edge of danger, from nuclear sites in France to ethical hacking in Perth. Today, as the Managing Director of Cyber Node, he helps organisations stay one step ahead of the invisible risks that threaten modern business.
In this conversation, we explore the psychology of endurance in marathons, in entrepreneurship, and in managing risk when the stakes are high. We talk about why most leaders still underestimate cybersecurity, how trust is the missing layer in protection, and what happens when you push beyond limits, physical or professional.
If you’re a business owner who’s navigating uncertainty, leading with grit, or wondering if you’ve got more in you, listen carefully.
