Cyber Security Governance & Culture - Enterprise Risk & Capability Transformation
"Dena designed and delivered a complete culture change programme at GSK. She changed the way people think about cyber security and their behaviours. She took advice from academics in the fields of psychology, sociology and criminology and undertook rigorous scientific experiments to demonstrate the effectiveness of different types of intervention, before rolling out interventions to the 150K employees and contractors at GSK. I am sure that I will work with Dena in the future and I would welcome the opportunity."
