The article discusses the issue of the use of Information and Communication Technologies (ICTs) in business management. The considerations focus on the role and importance of these technologies in the improvement of processes and management of business projects, and thus shaping the security of contemporary enterprises. The dynamic development of ICTs results in the possibility of their practical application in many areas of business operations. The article also highlights the effects that can be achieved by implementing ICTs in business projects. The research problem is as follows: What are the basic effects of the implementation of ICTs in business projects in the context of shaping the security of enterprises? The theoretical goal is related to the identification of the main effects of the use of ICTs in project management in modern enterprises. On the other hand, the utilitarian goal is to present the rules of practical use of ICTs in the management of business projects on the basis of the good practices/recommendations, and to indicate the benefits and risks (both organizational and business ones), resulting from the use of ICTs in project management – as the basis for activities related to shaping the security of enterprises. The main empirical method has been a case study (in a form of a multiple case study). The study also used methods of analysis and synthesis. The qualitative study, in the form of case studies, was covered a group of six companies (engaged in either the provision of services or production). Business profiles of these entities were diverse and included the following industries: building & construction, energy, fuel, financial, transport and interior design. Companies were included in the study due to the criterion of conducting business projects and the implementation of ICTs supporting this activity.
