The traditional perimeter-based security models are increasingly inadequate in safeguarding modern enterprise networks, characterized by cloud adoption, remote work, and mobile device integration. Zero Trust Architecture (ZTA) offers a paradigm shift by enforcing the principle of "never trust, always verify," irrespective of the user's location within or outside the corporate network. This paper explores the evolution, implementation strategies, and effectiveness of ZTA in next-generation enterprise environments. Through a systematic literature review and case studies, we examine the core components of ZTA, including identity and access management, micro-segmentation, and continuous monitoring. The findings highlight the enhanced security posture ZTA provides against advanced persistent threats and insider attacks. However, challenges such as integration with legacy systems, scalability, and user experience concerns are also discussed. The paper concludes with recommendations for organizations considering ZTA adoption and outlines potential areas for future research.
