As @`Xanny` and others have pointed out already, their are a lot of issues with Umbrel and personally wouldn't direct a noobs toward them. Noobs are looking to get rekted.

While I can't comment on the below pages claims and the author does admit bias working for a competitor, it does point out a lot of historic security issues with Umbrel and their response that should give anyone pause before purchasing any of their stuff. Not spreading FUD just spreading knowledge.
