In this episode of CXO Secrets, David McClelland is joined by Darren Humphries, Group CISO & CTO Partner at Acora and Arron Thundercliffe, Cyber Defense & Threat Intelligence at Google for a deep dive into the evolution of cyber defence. Together, they explore the shift from traditional perimeter security to cloud-native, AI-driven strategies, the fragmentation of IT responsibilities, and the growing importance of identity, behavioural analytics, and DevSecOps. From malware in the 2000s to IOT vulnerabilities and smart fridges, this episode uncovers why today’s threat landscape demands a holistic, integrated approach to cybersecurity—and how organisations can start to achieve it.
