<p>Online crime prevention is difficult and contemporary strategies have largely failed to produce appreciable effects. The internet is expansive and haphazardly constructed, rendering it difficult to engage in crime control practices that mirror terrestrial environments. This essay reviews prominent classical and neo-classical crime prevention strategies, their application to cybercrimes, as well as why these efforts have largely failed online. It then details a vision for cybercrime prevention policy focused on a democratic, transparent, and public-sector drive to integrate the multitude of online actors into a robust and cohesive security agenda. While such an agenda may be out of reach (for now), criminologists have an instrumental role in answering vital policy-related questions and helping map out the blueprint for online security.</p>
