This document describes requirements, as identified by the stakeholders of CyberSec4Europe, for the seven vertical areas that have been defined in the project: Open Banking, Supply Chain, Privacy-preserving Identity Management, Security Incident Reporting, Maritime Cybersecurity, Medical Data Exchange, and Smart Cities. The findings and recommendations are based on the works of Task 4.1, which focuses on engaging the vertical stakeholders of the project, so as to collect their needs, the problems they face, and the challenges they will be forced to meet in the near future. A combination of methods was used for eliciting the requirements from the stakeholders, and receiving their feedback on important cybersecurity problems and approaches needed to deal with them for their respective economic sectors. These methods comprised online questionnaires, structured interviews, a number of brainstorming workshops, and desk research. The conclusions of our analyses, presented in this document, show that the stakeholders envision resilient systems, infrastructures, and societies as their common objective. It emerges from this task that their needs will only be fulfilled by an environment that wisely encompasses regulation, incentives, structural reorganisations, and capacity building, along with research and deployment of new technologies, as detailed in the text.
