The author presents the results of research carried out in property and personal security companies. The research was carried out both on the basis of a theoretical method based on qualitative analysis of legal acts, critical analysis of scientific literature as well as the empirical method consisting of using research tools such as questionnaires and expert interviews. The research came up with a positive answer to the question: Is it possible to increase the participation of property and personal security companies in ensuring public safety in Poland? The author believes that it is necessary to create a symbiotic formal and legal system that determines the use of human resources in broadly considered state security and in the process of implementing the objectives of national security policy by all levels of government either, state, local or private. The author notes that enhancing the efficiency of security entities is possible, inter alia, through continuous technological development and the exchange of knowledge between national security entities and the authorities responsible for managing security through regulation. According to him, the exchange of knowledge, experience and information between the public and private sectors, and the implementation of best practices in the field of security for day-to-day practice, improves the effectiveness of security policy. One such preventive measure is the creation of a formal and legal basis for conducting a security policy based on an integrated system of exploitation of experience, in which all entities responsible for the security of the Republic of Poland participate. This publication indicates the direction of action that the author believes should be taken to make better use of the private security sector in the state security system.
