Endpoint Security is the previous name for Harmony Endpoint, which actually contains a number of components which may or may not be deployed and/or licensed in your case.
You're probably not running the most recent version of Harmony Endpoint if you're not seeing that name anywhere.
See the screenshot from the video showing how Harmony Endpoint protects you showing the components enabled/installed and the version (E86.40).
The video comes from the blog post referenced above and the screenshot links to the video.
