Helping Bank of East Asia Build a Global Security Management System to Enhance Digital Resilience

Key Challenges

Bank of East Asia (BEA) lacked visibility across its globally distributed environment, making it difficult to achieve the core objective of its fintech strategy — digital resilience. Additionally, regional teams had to operate their own local SIEM systems, resulting in extremely time-consuming and inefficient troubleshooting processes.

Key Outcomes

As one of the first local banks to adopt cloud-based SIEM, BEA built a centralized international SIEM platform using Splunk Cloud Platform, achieving network-wide security visibility while significantly reducing manual troubleshooting time.

BEA Leverages Splunk for Global Security Management and Enhanced Digital Resilience

Technology at its best brings people closer together.

As a publicly listed financial services group with over a century of history and headquartered in Hong Kong, Bank of East Asia (BEA) provides comprehensive banking services to customers through more than 130 service points worldwide. In recent years, BEA has actively driven technological innovation by launching the BEAST (BEA Smart Technology) initiative, partnering with local startups to continuously nurture the local fintech ecosystem.

BEA has long relied on Splunk Enterprise Security to monitor its on-premises infrastructure. To unify global SIEM management, BEA once again chose Splunk as its technology partner and officially moved to the cloud. By deploying Splunk Cloud Platform, BEA became one of the earliest financial institutions in Hong Kong to adopt a cloud-native SIEM architecture, comprehensively enhancing security visibility across its global environment.

Results Highlights

Regional SIEM deployment in just 1 month, compared to months previously
Centralized visibility across globally distributed environments
Manual troubleshooting hours reduced to zero, dramatically improving response efficiency

The Efficiency Leap from a Centralized Strategy

It used to take months to set up infrastructure. Now we can deploy a complete SIEM system in just one month. — Stephen Leung, Head of Information Technology and Fintech Development, BEA

Through a centralized architecture, BEA's Hong Kong headquarters can now pull security data from any location worldwide in real time. Previously, regional branches had to build their own SIEM systems and contact headquarters for analysis on every incident. Now, headquarters can directly share Splunk visualization dashboards with subsidiaries, giving every regional team complete local security situational awareness — proactively identifying risks, rapidly responding to issues, and improving overall security maturity.

After migrating to Splunk Cloud Platform, we can uniformly collect security events from on-premises and cloud environments globally, gradually expanding from Hong Kong to Macau, Taiwan, Singapore, the UK, the US, and beyond. — Leung

Splunk Cloud Platform's SaaS architecture has also significantly reduced BEA's investment in configuration and maintenance, enabling rapid deployment and flexible scaling, and helping the team focus on business security and efficiency improvements.

Solutions Used

Platform Observability

Automation Enhances Agility

In security, an ounce of prevention is worth a pound of cure.

BEA introduced Splunk SOAR (Security Orchestration, Automation and Response) to enable automated alert response and workflow orchestration. With real-time contextual awareness and threat intelligence, analysts can efficiently handle security incidents and move away from repetitive processes to focus on more strategically valuable tasks.

Splunk helps us make smarter security decisions while ensuring stable operations across regions around the clock. — Leung

Splunk has also strengthened BEA's digital resilience capabilities in three key areas:

Real-time troubleshooting
Tracking threat evolution trends
Maintaining business agility in cloud environments All of this ultimately points to one goal: delivering a safer, more reliable banking experience for customers.

Pushing the Boundaries of Digital Resilience

As one of the first banks in Hong Kong to implement cloud-based SIEM, BEA continues to drive the execution of its fintech strategy. Leung states:

Digital resilience is a core component of our fintech strategy. We are committed to strengthening cybersecurity while fostering a culture of innovation to navigate the rapidly changing digital landscape.

BEA leverages Splunk to enhance automation, achieving more efficient system monitoring, patch deployment, and threat response. Going forward, Splunk Cloud Platform will continue to provide scalable technical capabilities to accommodate growing use cases and business demands.
