In the context of escalating cyber threats and the rapid evolution of digital work environments, traditional security models based on perimeter defense are increasingly proving inadequate. The Zero Trust model introduces a fundamental paradigm shift by eliminating the assumption of trust within corporate networks and instead adopting a continuous verification approach. This article explores the core principles and architectural components of Zero Trust, highlights its operational and strategic advantages over legacy systems, and examines the practical challenges organizations face during implementation. Particular attention is paid to how Zero Trust addresses modern cybersecurity risks such as remote work, cloud infrastructure, insider threats, and the proliferation of mobile and IoT devices. The study also analyzes real-world applications, including Google’s BeyondCorp framework, and provides practical recommendations for organizations of various sizes seeking to enhance their security posture. By offering a comparative overview and actionable guidance, this paper contributes to the development of adaptive, scalable, and resilient cybersecurity strategies for enterprises operating in a rapidly changing digital landscape.
