Case Study: University Hospital Zurich achieves 100% threat protection with Palo Alto Networks

100% threat protection leads to safer, stronger medical care

University Hospital Zurich (UHZ), a major European medical center with more than 8,400 employees and over 13,000 distributed endpoints, needed more consistent, low‑impact endpoint security to protect patients, staff and critical systems—requirements that became even more urgent as thousands of employees shifted to remote work during the COVID‑19 pandemic.

UHZ migrated from its legacy on‑premises solution to Palo Alto Networks Traps and then to cloud‑delivered Cortex XDR, leveraging AI/ML behavioral protection. In proof‑of‑concept testing Traps blocked 100% of tested threats versus 40% for the previous product (2.5× improvement); Cortex XDR then scaled quickly to secure thousands of remote users, reduced resource use on virtual desktops, simplified management, and delivered markedly improved malware prevention and uptime.
