The Challenge

Fragmented Tools, Complex Threats, and SOC Overload

As the largest bank in the Czech Republic, Česká spořitelna plays a critical role in the country’s financial ecosystem — serving over 5 million clients and being part of the Erste Group, which operates across Central and Eastern Europe with over 16 million customers.

Like many large enterprises, the bank was facing growing cybersecurity and operational risks driven by an increasingly complex ICT environment. One of the main challenges was the need to increase infrastructure resilience to better respond to modern cyber threats.

The security landscape included a variety of disconnected tools and a siloed environment, making it difficult for SOC teams to manage incidents effectively. Moreover, SOC capacity was limited, creating bottlenecks and increasing response times. The organization needed a solution that would unify security data, reduce tool sprawl, and enhance both detection and response capabilities.

The Solution

Splunk-Powered SIEM for Unified Security Operations

To address these challenges, we implemented a comprehensive Security Information and Event Management (SIEM) solution based on Splunk Enterprise and Splunk Enterprise Security.

This modern platform enabled centralized security monitoring, providing a single point of visibility for logs, alerts, and incident data across the bank’s entire ICT infrastructure. By consolidating diverse data sources and tools, the solution streamlined operations and empowered the SOC team with better insights and faster decision-making capabilities.

The SIEM implementation also laid the foundation for advanced use cases such as automation, SOAR (Security Orchestration, Automation and Response), and analytics-driven threat detection.
