Abstract
This study critically examines the transformative impact of Zero-Trust Architecture (ZTA) on organizational cybersecurity by employing a systematic literature review methodology. In an era where traditional perimeter-based defenses are increasingly vulnerable to sophisticated cyber threats, ZTA represents a paradigm shift by eliminating implicit trust and enforcing continuous verification of every access request. The research evaluates the role of ZTA in enhancing security postures, ensuring regulatory compliance, and supporting scalable operations in hybrid and cloud-based environments. The analysis reveals that ZTA significantly improves network visibility and threat detection through continuous monitoring, thereby mitigating risks associated with insider threats, advanced persistent threats, and credential-based attacks. While the granular controls and real-time risk assessment offered by ZTA foster proactive risk management, they also introduce challenges related to the integration with legacy systems and the substantial initial investments required for deployment. These challenges underscore the complexity of transitioning from traditional security models to a zero-trust framework. The study highlights the dual-edged nature of ZTA: its advanced security capabilities provide robust defenses against modern cyber threats, yet its implementation demands careful planning and phased adoption to minimize operational disruptions. Overall, this critical evaluation underscores the necessity for ongoing refinement of ZTA frameworks to address both technical and organizational challenges, paving the way for more resilient and adaptive cybersecurity strategies in complex digital environments.
