The threat of cybersecurity incidents is increasingly challenging for companies and employee interaction plays a crucial role in the majority of cyberattacks. In this paper, we present a mobile, scalable IT-security lab to investigate the human factor in such incidents. The lab enables study participants to experience cyberattacks in an immersive workplace environment. In order to ensure that the target group of small and medium sized company (SME) employees is reached, we have designed the mobile lab in such a way that it can be easily operated in different locations and sizes.
