New epissodes coming soon! Cyber security has rocketed to the top of corporate risk registries in recent years. But few board members attain their place due to any deep subject matter expertise.  In this week's CXO Challenge, we speak to Roger Sharp the founder of North Ridge Partners, and the chair of several large listed companies in the finance and travel sector in Australia. Sharp talks about the need to take an holistic approach to the subject.  We also discuss the challenge generally for directors to stay on top of the topic of technology driven transformation in an age of rapid digital acceleration.
