The Elastic Infosec Detections and Analytics team leverages the Elastic Stack to secure its distributed enterprise network by utilizing innovative approaches tailored to its unique, remote-first environment. The team, known internally as Customer Zero, employs Cross Cluster Search (CCS) to manage and monitor data across multiple clusters, allowing analysts to access and analyze security events from a single Kibana interface. This architecture supports seamless incident response and threat detection, as evidenced by their ability to quickly investigate and respond to potential security breaches, such as compromised user accounts. By using CCS, Elastic avoids the pitfalls of centralized data storage, such as single points of failure, while maintaining data integrity and regulatory compliance. The setup also facilitates testing and upgrading without disrupting production clusters, ensuring that both Elastic’s internal processes and customer solutions remain robust and efficient.
