Summary
Key results
Automated repetitive incident-handling tasks with playbooks in Microsoft Sentinel and Splunk Phantom, shortening analysis and escalation times.
Higher SOC efficiency and lower operating costs through automation of event correlation and data enrichment.
Cybersecurity under regulatory pressure and operational constraints
The bank processes a massive volume of security events daily, requiring rapid response and precise analysis. Existing processes lacked sufficient automation, prolonging incident handling, increasing the risk of human error, and inflating SOC operating costs. The organization needed a partner to drive SIEM/SOAR automation and to advance its Microsoft Sentinel, Splunk, and Splunk Phantom platforms.
Two specialized delivery streams
- Microsoft Sentinel team — responsible for platform development, automated playbook implementation, and integration with incident-management processes.
- Splunk + Phantom team — focused on enhancing SIEM/SOAR mechanisms, automating event flows, and integrating with the client’s systems.
Scope of work included:
- Automating incident-handling workflows.
- Enriching event data from external sources.
- Creating correlation rules to detect complex attacks.
- Developing custom queries for log analytics.
- Integrating automation with SOC processes.
Faster response, fewer errors, lower costs
Partnering with Sii Poland enabled the client to significantly reduce incident response times, lower the risk of human error, and cut SOC operating costs. Automated event-handling processes improved efficiency and allowed the organization to scale operations globally—laying a solid foundation for continued optimization and security maturity.
