This study investigates the factors influencing the implementation of cybersecurity in the Philippine Coast Guard (PCG) to ensure national security and maritime safety. The research focused on policies, circulars, developmental plans, equipment, and human resources. A mixed-methods approach was used, collecting quantitative data through a survey of 90 MARSLEC personnel to assess their cybersecurity awareness and perceptions of current measures. Qualitative insights were obtained from in-depth interviews with deputy commanders of MARSLEC units. The results revealed key obstacles: unclear policies and circulars, limited budget and resources for cybersecurity equipment, and insufficient specialized training and skilled personnel. Despite these challenges, there was a strong commitment from PCG leadership to prioritize cybersecurity. Effective collaboration with other agencies and organizations was deemed crucial. The study recommended addressing these challenges by clarifying policies, optimizing resource allocation, and implementing continuous training and awareness programs. By improving cybersecurity readiness, the PCG could better safeguard national interests, maritime assets, and personnel against evolving cyber threats. These measures are essential for enhancing the PCG's cybersecurity posture and ensuring resilient maritime operations.
