The relevance of the study is conditioned by the rapid development of digital technologies and the need for linguistic understanding of how specialised terminology forms a professional picture of the world in the field of cybersecurity. The purpose of the study was to identify, systematise, and cognitively interpret conceptual metaphors in contemporary English-language cybersecurity terminology, and to determine their role in the processes of conceptualisation of digital threats and defence mechanisms. The research was based on the provisions of the theory of conceptual metaphor and was aimed at identifying mechanisms of linguistic conceptualisation of abstract processes related to information security, digital threat management, and the functioning of cyberspace. The material of this scientific research consisted of 4,000 English-language terms selected from the authoritative English-Ukrainian dictionary of terms on information technology and cybersecurity. The methodological basis was cognitive and metaphorical analysis, semantic classification, component and quantitative analysis, which helped to establish the hierarchy and performance of metaphorical models in the terminology under study. As a result of the analysis of cybersecurity terms, it was found that a significant part of them was formed based on conceptual metaphorisation. The most productive were ontological metaphors (436 units), in which cybersecurity was understood as a control, system, cipher, or data storage container. A significant group consists of natural metaphors that include models of fluids, plants, and animals, and medical metaphors related to the conceptualisation of computer viruses. Among the structural metaphors (416 units), the metaphor “cybersecurity is military operations” (attack, threat, combat, weapons) dominates, and the architectural model “cybersecurity is home” (access keys, locks, gateways). Orientation metaphors turned out to be small in number and perform mainly a navigation function, providing a hierarchy of concepts such as threat level, security level, attack vectors, and system boundaries. The practical significance of the study lies in the possibility of using its results in research on cognitive linguistics, terminology, discourse analysis, and in training courses and applied developments related to digital communication and information security
