Child rights advocates, parents, governments, and children themselves are increasingly calling for digital safety by design, so that children can be protected online, and also benefit from positive digital experiences. However, the exact meaning of digital safety by design can be unclear. This report explores the concept, considering how it is addressed at international and national levels. Internationally, there are common calls for the proactive integration of safety measures into digital products and services, as well as for transparent, accountable and child-friendly service delivery. National laws prescribe practical tools and measures such as age assurance and accessible complaint mechanisms. Focusing on actions for digital service providers, the report suggests eight key components for digital safety by design for children, including practical tools, measures to foster a culture of safety, and harm mitigation strategies. These components are illustrated through case studies, highlighting a need for diverse and tailored approaches.
