Abstract	Zero-trust security models offer a robust paradigm for safeguarding healthcare IT infrastructure by enforcing continuous verification and eliminating implicit trust, leading to substantial reductions in cyber risks such as ransomware and data breaches. Across synthesized evidence, implementations demonstrate a two-thirds reduction in overall cyber risks and over 95% accuracy in detecting threats from Internet of Medical Things (IoMT) devices, with case studies showing decreased unauthorized access and improved breach containment compared to traditional perimeter-based defenses. These models integrate core components like identity verification, micro-segmentation, and AI-driven anomaly detection to protect electronic health records (EHRs), telemedicine systems, and distributed networks, particularly amid rising incidents like the 276 million records breached globally in 2024. The escalating digital transformation in healthcare, including AI, cloud computing, and hybrid workforces, has amplified vulnerabilities, rendering legacy perimeter defenses inadequate against evolving threats that compromise patient safety and operational continuity. This review synthesizes findings on model applications, benefits, challenges, and evaluations, revealing consistent advantages in regulatory compliance (e.g., HIPAA) and resilience, though implementation hurdles persist. Key secondary insights include enhanced protection for sensitive data across multiple access points, with qualitative analyses of breaches illustrating faster threat isolation and minimal lateral movement. Practical implications emphasize the need for pilot programs and standardized guidelines to facilitate adoption, while gaps remain in empirical validations for legacy-heavy environments and cost-benefit analyses. Overall, zero-trust frameworks promise transformative cybersecurity in healthcare, but require tailored strategies to overcome resource constraints and ensure seamless clinical integration.
