Case Study: Canadian International School of Hong Kong achieves lightweight, zero‑impact endpoint protection with Palo Alto Networks Cortex XDR

CDNIS Boosts Security at Home and on Campus with Cortex XDR Prevent

Canadian International School of Hong Kong (CDNIS) is a respected independent school of about 1,800 students and 300 staff that relies heavily on technology for learning. The school’s legacy antivirus was processor-intensive, slowing devices and frustrating users, and it struggled to address modern threats and zero‑day attacks—especially as many devices began connecting from home during the COVID-19 shift to remote learning.

After a proof-of-concept, CDNIS deployed Palo Alto Networks Cortex XDR Prevent across more than 2,000 endpoints in two weeks, integrated with existing Next‑Generation Firewalls. The lightweight agent runs invisibly with no measurable performance impact, centralizes management via an intuitive dashboard, and delivers behavior‑based, AI-driven protection against advanced malware, exploits and fileless threats—giving the school seamless, campus‑and‑home security and greater confidence against new threats.
