Most usability evaluation methods are designed to be applied after the implementation of a software product. As such, there is limited research on how to conduct usability evaluation procedures before the implementation of a software product, especially on cybersecurity platforms user interfaces. For this purpose, we illustrate the early usability evaluation of a cybersecurity graphical interface. In this sense, we conduct a usability evaluation procedure on the mockup of Yggdrasill, an application centered on the early identification of vulnerabilities using open-source intelligence, more specifically Tweeter posts and news websites. To achieve this, we conducted a usability inquiry procedure using the adaptation of a questionnaire designed to evaluate the attractiveness of interactive products. In addition, we conducted a usability testing procedure based on the think-aloud protocol. The results of this study enabled the timely identification of improvement opportunities for the graphical interface of the Yggdrasil graphical interface before the actual implementation.
