Mission Control (MC), currently in Preview, is a security operations application from Splunk Security. When all features are released, it will unify capabilities from Splunk Core, Enterprise Security, SOAR, and Threat Intelligence Management.
This release of Mission Control, known as “Preview 1”, provides the initial infrastructure for the app, the ingestion framework to move ES incidents into MC, and the framework for response capabilities via a feature called Response Templates. It is a great way to see how the product is shaping up and what the fundamentals of Mission Control look like! Check out the docs here for more info! https://docs.splunk.com/Documentation/MC/Preview/
Note that the app is currently in an early release preview.
