Online education including MOOCs (Massive Open Online Courses) have steadily gained importance during the COVID-19 pandemic. They also play an important role for enabling lifelong learning and addressing the cybersecurity skills gap. However, it is not always easy to judge the quality of MOOCs for learners or other stakeholders including organisations interested in cybersecurity MOOCs as a means for competence development of their employees. This article provides an overview of the research work conducted by the EU H2020 projects CyberSec4Europe and CONCORDIA on eliciting quality criteria for different types of cybersecurity MOOCs provided in Europe, on defining a quality branding process that was validated through trial evaluations of selected cybersecurity MOOCs, and on conducting a survey with cybersecurity MOOC stakeholders and interviews with certification experts about the role and form of quality certification. Based on this research, the article concludes by proposing building blocks for a “lightweight” certification scheme for future quality branding of cybersecurity MOOC.
