KPN Security Services, a SOC/SIEM security management company from the Netherlands, has harnessed the Elastic Stack to tackle the challenges of managing rapidly growing and complex data volumes while maintaining its commitment to preventing and responding to threats. At an Elastic{ON} Tour event in Amsterdam, KPN representatives Han Pieterse and Marius Iversen discussed how the Elastic Stack helps mitigate "security data overload" by enhancing data analysis, visibility, and management, enabling the 400-member security team to focus on core security functions. Before adopting the Elastic Stack, KPN's single-tenant, manually configured setup limited scalability, but the integration of the ArcSight Logstash plugin and multiple data pipelines through Kibana dashboards simplified data ingestion and improved efficiency. KPN plans to leverage the Elastic Stack's machine learning capabilities for security and non-security purposes, such as monitoring server activities for breaches, detecting anomalies in financial transactions and employee behavior, and forecasting resource requirements to prevent memory shortages.
