This chapter merges theories of digital criminology and vulnerability to contribute to conceptualisations of digital vulnerability. It explains digital criminology as a critical criminological theory that builds on sociological literature to examine the reciprocal relationships between law, justice, society and technology. The chapter then surveys vulnerability theories to show how understandings of vulnerability are varied and contested. A merger of digital criminology with vulnerability theories gives rise to digital vulnerability as a framework for asking: what new social solutions or harms arise when vulnerable people, who seek access to justice, are remote from court?
