In 2019, Callum joined the Cabinet Office, where he currently serves as Head of Public Sector Cyber Defence. This work holds a particular emphasis on uplifting the cyber resilience of the emergency services, the health sector, the justice sector, the welfare sector, the Devolved Administrations and local government – an issue of increased importance following the Covid-19 pandemic. Alongside this role, Callum serves as the Chair of the Cabinet Office Ethics Network, a forum dedicated to the discussion of practical ethics within central government decision making, policies and programmes. In this capacity, Callum is concerned with creating a safe space for ethical discussion across Government whilst personally specialising in the ethics of cyber security and Government digital strategy.
