Ensuring corporate security is an essential and critical component of any healthcare facility to provide safe services to its patients and employees. Healthcare facilities must employ a variety of strategies to ensure corporate security. This includes developing a comprehensive communication plan that defines the roles and responsibilities of the various stakeholders. The objective of our study was to present the concept of corporate security in healthcare institutions and in the Slovenian healthcare system, to highlight current threats in healthcare institutions in Slovenia, to describe the importance of strategic communication of corporate security in healthcare, and finally to define the current state of corporate security in Slovenian healthcare institutions in Slovenia. A survey was conducted and distributed to healthcare institutions in Slovenia to obtain results. A total of 154 healthcare stakeholders participated in our study. The results showed that corporate security is present in Slovenian healthcare facilities, but additional efforts are needed to improve it, especially considering the current challenges related to the measures taken after the COVID-19 epidemic and the shortage of healthcare personnel. The legal processes of corporate security in healthcare facilities comply with applicable laws and regulations to protect the interests of their patients and employees. Operational security processes are currently provided primarily by internal providers. There is a need for improvement, particularly in the training and education of staff, who play the most important role in ensuring safety. To effectively establish comprehensive corporate security, strategic communication with all stakeholders is essential to ensure that their security policies and procedures are properly implemented.
