The term “extremism“ signifies extreme activities and views which oppose democratic order or are aimed at a violent overthrow of Croatia's democratic constitutional order. SOA monitors all types of extremism, regardless of its ideological, political, religious or national background.

Countering extremist activity involves protecting citizens from violence, threats of violence, intimidation, encouraging the violent overthrow of democratic constitutional order and endangering of their constitutional rights and liberties. We are responsible for monitoring persons involved in extremist activities insofar as they encourage or conduct activities that violate Croatian laws or express calls for violence and national, ideological, racial or religious hatred. SOA also makes assessments regarding the activities of extremist groups from neighboring countries which pose a threat to security environment in Croatia or to regional stability.

Cyber space is very significant for extremist and similar types of activities as it allows individuals to exchange information and spread extremist views. Thus, the Internet has become one of the most important media tools for spreading extremist ideas.
