The study of the effectiveness of the case studies of the project “Enhancing the capabilities of law enforcement agencies in combating violence against children on the Internet” aims to assess and analyze the use of best practices implemented in Kyiv, as well as in Vinnytsia and Lviv regions. The use of experience and dissemination of products developed during the project will contribute to strengthening the effectiveness of management in the field of combating violence against children on the Internet and their protection in cyberspace. Raising awareness of partners and implementing effective tools for responding to violence will contribute to the safety of children. The publication highlights the best approaches, methods and tools created to strengthen the capacity of key stakeholders in this area. Based on the assessment of cases and the experience of the project, recommendations were developed that are useful for key partners in their work in all regions of Ukraine. The publication is based on the results of a study conducted by the NGO “Social Initiatives for Occupational Safety and Health” (LHSI).
