Tom Owen

Chief Information Security Officer, iloomi

I believe that success is built on respect, empathy and communication, that if you care deeply about people they will do amazing things. Security is fundamentally a data and visualisation problem. If you want to decentralise security (and you should) then you need to distributed and solve for enablement and accountability.

Able to articulate and engage at all levels of the business, from a SOC analyst or software engineer up to the Board. I believe that success is built on empathy, respect, collaboration and communication. I aim to be an agent of positive change and enable business performance and growth, supporting distributed risk ownership whilst allowing the board to better understand, articulate and address their real risk posture.

A particular interest in fostering conversations around ethics, sustainability, mental health and inclusivity.
