The increasing integration of digital technologies in maritime operations has significantly enhanced efficiency in cargo tracking, port management, and communication systems. However, this digital transformation also introduces substantial cybersecurity risks, particularly in developing regions like Tanzania, where technological infrastructure and specialized skills may lag behind global standards. This study evaluates the cybersecurity readiness of three key Tanzanian maritime organizations Tanzania Ports Authority (TPA), Tanzania Shipping Agency Corporation (TASAC), and SINOTASHIP using the Cybersecurity Capability Maturity Model (C2M2). Through a detailed assessment across ten C2M2 domains, the study identifies existing strengths and critical gaps in areas such as risk management, asset management, and incident response. The findings reveal that while basic cybersecurity practices exist, they are largely reactive, with most domains scoring between Level 1 (Initial) and Level 3 (Defined). This lack of advanced, proactive measures poses significant risks to Tanzania's maritime infrastructure, particularly given the strategic role of ports like Dar es Salaam in regional trade. The study highlights the need for tailored improvements, including enhanced asset management, continuous workforce training, and real-time monitoring systems, to bridge the gap between global standards and local practices. By implementing these measures, Tanzanian maritime operations can strengthen their resilience against cyber threats, ensuring secure and efficient port operations in an increasingly interconnected world.
