Splunk Enterprise Security (ES) is a leading, analytics-driven Security Information and Event Management (SIEM) solution built as a premium application on the highly scalable Splunk operational intelligence platform. It is designed to help Security Operations Center (SOC) teams detect, investigate, and respond to internal and external attacks by centralizing and aggregating all security-relevant events from diverse sources like network, endpoint, access, malware, vulnerability, and identity systems.
The platform provides a unified work surface and streamlined workflows for threat detection, investigation, and response (TDIR) by natively integrating with Splunk SOAR (Security Orchestration, Automation, and Response). Key capabilities include real-time monitoring and alerting, advanced threat detection utilizing machine learning and analytics, and risk-based alerting to prioritize high-confidence threats. The solution is highly valued for its powerful Search Processing Language (SPL), robust log aggregation, and extensive third-party integration options available through the Splunkbase app ecosystem.
Splunk ES is highly scalable and flexible, supporting deployment across on-premise, cloud, and hybrid environments, and is best suited for large organizations and enterprises with well-staffed IT teams due to its complexity and high cost.
