Abstract: Ensuring people's protection is an increasingly demanded requirement, both at political and corporate levels. Within the Spanish legislative system, organizations are obliged by law to develop and maintain the so-called Self-Protection Plan (SPP). In this work, we introduce DIMEPRO, a tool that provides organizations with means to evaluate and improve the management of their SPPs (SPPM). DIMEPRO is based on the QuEP-framework, which evaluates the maturity an organization has reached regarding its SPPM. DIMEPRO aims to become the reference tool for organizations chosen to improve their self-protection; to the best of our knowledge, DIMEPRO represents a pioneer system in addressing this problem since no other tools have addressed the same problem. This tool allows the diagnosis of SPPM and provides a set of best practices that will allow a roadmap for its improvement. The results of the assessments are displayed in dashboards, as well as in reports of different natures.
