This study presents a methodology for implementing an open-source tool to strengthen cyber defense in response to growing cybersecurity challenges in public administration. It highlights the advantages of open-source software in terms of cost and flexibility, especially given the budgetary constraints and lengthy administrative processes that hinder technology adoption in many LAC countries. In addition to implementation, other open-source solutions are integrated to extend cybersecurity capabilities, thus providing a holistic approach to addressing threats in the digital environment.
