In order to access valuable indicator information in the field of cybersecurity, domain experts tend to use visualizations to quickly gain an overview of a given situation, even more so in the age of big data where initially following visual summaries tends to be more efficient before diving into raw data. For this purpose, researchers analyze the visual and functional requirements of systems to facilitate data exploration. In this paper, we conduct a trend analysis of latest research contributions presented in VizSec symposia in terms of visualization techniques and functional requirements. Additionally, an international and a currently ongoing national project, focusing on Local Public Administrations (LPAs) and Critical Infrastructures (CIs) are analyzed and compared to current state-of-the-art research in terms of requirements of real users in the field of CIs and LPAs. Particularly, a deficiency concerning the requirements of collaboration, enhanced situational awareness, multi-stakeholder involvement, and multi-stakeholder visualization were identified and are discussed in the context of the utilization of cybersecurity visualizations in their work environments.
