Sexual exploitation, abuse and violence against children is not a new phenomenon but today it takes on a new dimension. The Republic of Croatia strives to protect children with its legislative framework, and as a member of the UN, it is a signatory to the Convention on the Rights of the Child, as well as relevant international documents that additionally protect children's rights and interests. With the rapid advancement of technology, life is largerly taking place in the virtual world, and with the emergence of the COVID-19 pandemic, the world became isolated, which resulted in an increase in the number of sexual exploitation of children and violence in general. Considering that the signs of sexual exploitation are difficult to recognize, the education of experts, the timely response of competent authorities and the harmonization of the use of terminology are essential. Likewise, children should be warned of potential dangers, educated in computer literacy and sex education. As children are the most vulnerable group of society and are unable to defend their rights themselves, all competent bodies are there to advocate for their well-being and best interest.
