The field of Preventing and Countering Violent Extremism (P/CVE) has witnessed significant growth in empirical research over the past decade, particularly in the identification of risk and protective factors associated with violent extremism. However, the rapid expansion of the literature across disciplines such as psychology, criminology, and public health, coupled with access barriers like paywalls, has created challenges for integrating evidence into P/CVE practice. To address these issues, the Horizon 2020 project INDEED launched an online repository in 2022, providing a freely accessible, regularly updated database of studies on risk and protective factors related to violent extremism. This article examines how the INDEED repository supports evidence-based practices in P/CVE by offering an accessible tool for researchers and practitioners to consult and integrate relevant studies. It specifically explores the repository's potential to strengthen P/CVE programme development, and to facilitate evidence-based policing in P/CVE through advanced trainings and professional support. Finally, the article discusses the strengths and limitations of the repository, and reflects on future directions for advancing the repository’s contributions to evidence-based practice in P/CVE.
