Does Fleet do reporting like Kolide does? Can i make reports for MT staff thats shows how many systems are not up to date, how many systems have no firewall enabled, etc?

Sorry I missed this last week during the holiday in the US. Fleet does not do reporting per se but you could certainly run a live query to check firewall status and export those results as CSV. Most folks do report generation in Splunk, ELK, etc. after forwarding scheduled query logs from Fleet.
