Results of the survey on the perception of terrorist and sabotage threats among the experts of the EU Protective Security Advisors

This article presents the results of a survey on the perception of terrorist and sabotage threats by experts participating in the European Commission’s (DG Home) initiative EU Protective Security Advisors (EU PSA). The survey was conducted in February 2025 on a sample of 50 individuals representing EU PSA, EU institutions, and strategic project partners. The questionnaire covered several key aspects of terrorist and sabotage threats, including the types of potential targets, attack methods, and expected developments in hybrid threats. Respondents were also asked to assess which critical infrastructure systems require the highest priority in resilience-building efforts, as well as which counter-terrorism measures should be prioritised at the EU level. Additionally, the survey explored factors that could improve the security of protected facilities and identified the most likely perpetrators of attacks on EU critical infrastructure. The survey results provide valuable insights for shaping counter-terrorism and counter-sabotage policies at the EU level. The authors emphasise the necessity of standardising physical security measures and developing educational initiatives to build a security culture.
