We are using rport.io for the management of heterogeneous landscaped.
All your device appears on a dashboard. You can log in to windows and linux directly. It has some automation built in. You can execute scripts directly from the browser. Installing all updates to windows or linux machines can be done in parallel.
It's open-source and easy to install.
If the question is if someone recommended Goverlan Reach, I would recommend looking at open-source alternative first. Rport.io and meshcentral are doing almost the same with a higher level of security at no costs.
