Cyber Threat Intelligence (CTI) getting prominent in complimenting organisations' cybersecurity armoury. Many proposed standards and shared intelligence platforms are closely related to the organisations that can be able to afford the potentially required skills and the investment to orchestrate the intelligence prioritisation process. Despite its significance, Small and Medium Enterprises (SMEs) endured obstacles in realising the advantages of threat intelligence sharing.
This qualitative study investigates the challenges endured by SMEs in sharing CTI. Through semi-structured and written interviews, the study focuses on Digital Enablers and Digitally based SMEs in Europe to draw upon perspectives and experiences of policymakers, specialists, CTI experts and researchers in the field of cybersecurity. The study contributes to a deeper understanding of the complexities surrounding CTI sharing to enhance SMEs cybersecurity resilience, highlighting factors distinctively attributed to SMEs- lack of skilled resources, affordability, usability, confidentiality concerns, security awareness, integration conflict and poor management support. The study also sheds light on the SME threat landscape and proposes recommendations to enhance CTI sharing among SMEs. This study intends to contribute SME community by enabling a CTI-driven ecosystem for cybersecurity resilience.
