What is this menu bar icon with three right chevrons?
If it is opened on login, check login items, {~,}/Library/Launch{Daemons,Agents}/, or /var/db/launchd.db/com.apple.launchd.peruser.501/overrides.plist.

You could also try running sudo opensnoop and clicking one of the menu items.

Or search for the names of the menu items:

grep -r 'Inventory Scan' -onlyin /Applications/
mdfind '"Inventory Scan"' -onlyin /Applications/
