This study investigates the impact of risk management and agile methodology on the success of cybersecurity projects, emphasizing the mediating role of team collaboration within the financial sector. Based on a sample of 229 professionals, including IT specialists, project managers, and risk officers, data was collected using a structured survey instrument and analyzed through Structural Equation Modeling (SEM) using SmartPLS. The results confirm that both risk management and agile methodology have direct positive effects on cybersecurity project success. Additionally, both factors significantly enhance team collaboration, which in turn positively influences project outcomes, thereby confirming its mediating role in the relationship between these variables and cybersecurity project success. All proposed hypotheses were supported. The findings highlight the crucial interplay between management practices and team dynamics in ensuring project success. The findings also provide valuable theoretical insights and practical implications for enhancing cybersecurity initiatives in the financial industry.
