The aim of the workshop is to identify examples of capacity building efforts that have made a real difference in terms of enabling sustainable changes in criminal justice systems and of increased effectiveness of tools against cybercrime. Over the past decade, governments, international organizations, private sector as well as civil society organizations have been implementing numerous projects to address cybercrime at national, regional and international level. Some actions were more successful than others. It is important to capitalize on those experiences that had an impact and helped criminal justice authorities and societies to address cybercrime more effectively.
