For this episode of the Digital Trust podcast, Host Christian Redshaw welcomes CISO Neal Mullen of the HSE (Ireland). Neal details his evolution from a biomedical electrical engineer to a Global Head of Operational Resilience and ultimately, a CISO. His journey highlights the critical need for technical experts to acquire business acumen (pursued through diplomas and Master’s degrees) to shift from technical tasks to strategic leadership. Influenced by a protective ethos, Neal’s focus shifted from technical fixes to operational risk and business continuity. His key advice for IT professionals entering security today: avoid jargon, learn to speak the language of business risk, and utilize clear control frameworks.
