An attacker’s blunder gave us a look into their operations

I don't work in cybersecurity and, after looking at the site's homepage, couldn't exactly figure out from all the buzzwords what exactly is this product. The most concerning takeaway from this article for me is that the maintainers of Huntress (whatever it is) can keep a log of, as well as personally access, the users' browser history, history of launched executables, device's hostname, and presumably a lot of other information. How is this product not a total security nightmare?
