Splunk Security Essentials
Overview
Details
Security Content Library
Find security content for Splunk Cloud and Splunk's SIEM and SOAR offerings and deploy out-of-the-box security detections and analytic stories to enhance your investigations and improve your security posture.
Cybersecurity Frameworks
Identify gaps in your defenses and take control of your security posture with automatic mapping of data and security detections to MITRE ATT&CK® and Cyber Kill Chain® framework.
Data and Content Introspection
Gain visibility of the data coming into your environment to add context and telemetry to security events. Enrich your security detections with metadata and tags from the Security Content Library.
Security Data Journey
Get prescriptive security and data recommendations and establish a data strategy to develop a security maturity roadmap.
We have changed the security content delivery endpoint for ESCU to comply with Splunk guidance. This means that if you have SSE version 3.7.1 or lower, the last supported ESCU version is ESCU 4.22.0. In order to get the latest ESCU version, you will need to upgrade SSE to version 3.8.0.
