Case Study: Fortune 500 Bank achieves SOC modernization and 99.9% alert consolidation with Palo Alto Networks Cortex XSIAM

Cortex XSIAM reshapes SecOps for Fortune 500 financial giant

A Fortune 500 multinational bank in the Asia Pacific region — with 6,500 branches, 150,000 employees and 165,000 endpoints — faced growing cyberthreats, operational inefficiencies and strict regional regulations that its legacy SIEM (QRadar) and manual SOC processes could not meet. After a rigorous Proof of Concept against three vendors, the bank selected Palo Alto Networks’ Cortex XSIAM to modernize its SOC with an AI/ML-driven, cloud-native platform that could satisfy detection, automation and compliance requirements.

Cortex XSIAM was rapidly deployed, integrating 20 critical log sources in three days and scaling planned ingestion from 7 TB to 150 TB while selectively reducing unnecessary data by 35–40%. The platform consolidated 17 SOC tools into one, automated response with 21+ playbooks and BYOK support, fused 9+ threat intelligence feeds, reduced ~19,000 daily alerts to 17 actionable incidents (~99.9% reduction), detected 5,000+ attack scenarios in live simulations, and aligned operations with regional regulatory and audit requirements.
