MACIN platform allows cybersecurity maturity to be assessed in a structured manner that is adapted to the reality of industrial environments. The platform is based on the model developed by the CCI and aligned with C2M2, assessing 175 practices from 45 objectives, grouped into 10 domains with four dimensions: Processes, Technology, People, and Results. The methodology incorporates the participation of different functional roles and allows for assessment by organization, plant, or specific industrial process(es). The results obtained allow for comparison with previous results, benchmarking with the sector, and the generation of prioritized action plans. MACIN promotes continuous improvement and facilitates communication between technical and management profiles.
