There are various challenges regarding the development and use of cybersecurity standards for SMEs. In particular, SMEs need guidance in interpreting and implementing cybersecurity practices and adopting the standards to their specific needs. As an empirical study, the workshop Cybersecurity Standards: What Impacts and Gaps for SMEs was co-organized by the and SMESEC Horizon 2020 projects with the aim of identifying cybersecurity standardisation needs and gaps for SMEs. The workshop participants were from key stakeholder groups that include policymakers, standards developing organisations, SME alliances, and cybersecurity organisations. This paper highlights the key discussions and outcomes of the workshop and presents the themes, current initiatives, and plans towards cybersecurity standardisation for SMEs. The findings from the workshop and multivocal literature searches were used to formulate an agenda for future research.
