Splunk Security Essentials (SSE) is the best fit because it is specifically designed to help security teams explore, organize, and assess security use cases and detection content. A threat-informed defense workflow requires engineers to relate candidate detections to adversary behaviors, and SSE provides security-content views that map detections to the MITRE ATT & CK framework , enabling analysts to identify relevant tactics, techniques, and coverage gaps.

This capability supports a structured use-case development process: determine the adversary behaviors relevant to the organization, review available detections aligned to those behaviors, identify required data sources, and determine where additional detection coverage is needed. The supplied Cybersecurity Defense Engineer material reinforces this use of Splunk Security Essentials by associating it with MITRE ATT & CK analysis and industry-focused ATT & CK visualization.

Enterprise Security is the operational SIEM platform where detections execute, while the Enterprise Security Content Update app distributes security content. A “Supporting add-on for MITRE ATT & CK” is not the primary use-case development application described here.
