The study explored the role played by CMMI Maturity in improving cybersecurity process using CMMI maturity indicator level scale through shedding light on certain dimensions represented in cyber process management, level of cyber risk management, level of continuous improvement, training and competence management, change management, and performance and measurement management. The study adopted the descriptive approach. The population consisted of all employees in the cybersecurity departments and divisions in public institutions. Due to the large size of the population, the study sample included (384) individuals using the simple purposive method, and (400) questionnaires were distributed to the sample under study to ensure that there were no missing persons and that the application was applied to the specified sample. The researcher drew on the theoretical literature and previous studies to construct the questionnaire and formulate its statements. The results showed that organizations under study lacked a mature system for identifying, assessing, and effectively managing cyber risks. This reflected a weakness in adopting preventative strategies or clear response plans to address potential cyber threats. There was a lack of sufficient attention to regularly monitoring and evaluating cybersecurity performance. This situation might make it difficult to determine the effectiveness of implemented measures or identify strengths and weaknesses on time. Organizations did not pay sufficient attention to employee comprehensive training or developing their cybersecurity skills. This might reflect weak training programs or a lack of opportunities to acquire the knowledge and experience necessary to address digital risks effectively. The researcher recommended strengthening the cybersecurity culture within organizations through ongoing awareness campaigns targeting all administrative and technical levels.
