    In today’s digital environment, ensuring cybersecurity has become critically important for businesses, yet small and medium-sized enterprises (SMEs) often face limited resources, low awareness, and a lack of suitable tools. Although cyber threats aect both large and small organizations, SMEs are particularly vulnerable due to the frequent absence of a systematic approach to security assessment. According to the Estonian Information System Authority, many smaller organizations lack the capacity to adequately evaluate their cybersecurity needs. The aim of this master’s thesis is to analyse to what extent the self-assessment tool MASS (Measurement Application for Self-assessing Security) meets the needs of SMEs, with a focus on usability, clarity, and practical applicability. While MASS is not based on any specic standard, it is analysed here in the context of the F4SLE (Framework for Security Level Evaluation) framework, which supports maturity-level assessments in cybersecurity. The study concentrates on the experiences, expectations, and practical challenges SMEs face when using the tool. The empirical part includes semi-structured interviews and expert evaluations to gather input on user experience and functional requirements. The analysis highlighted four main development needs: improving the questionnaire’s structure and usability, enabling role-based completion, adding a proling page, and enhancing linguistic clarity. This thesis contributes to a little-studied area in Estonia– the adaptation of cybersecurity self-assessment tools for SMEs– and presents concrete recommendations for improving the usability and applicability of the MASS tool.
