Case Study: Fortune 500 Australia-based multinational bank achieves Zero Trust security and improved user experience with Palo Alto Networks

Financial services leader goes from network frustration to a platform for innovation

A Fortune 500 multinational bank with more than 1,100 branches and 55,000 users was hindered by a disjointed, legacy network that left it exposed to cyber risk, compliance failures and service disruptions, made remote work hard to scale during the pandemic, and took up to 12 hours to resolve basic application issues.

Partnering with Palo Alto Networks, the bank deployed PA‑Series firewalls, Prisma SASE (Prisma Access and Prisma SD‑WAN) and cloud‑delivered security services (Advanced Threat Prevention, Advanced URL Filtering and Enterprise DLP) to implement Zero Trust, centralize operations and secure remote access. The changes drove measurable gains: nearly 50% higher internal app scores, more than a 40% drop in performance-related trouble tickets, a 97% increase in sensitive-data detection accuracy, and overall improvements in user satisfaction, IT efficiency and security efficacy.
