I've been following along this dude's videos:
https://www.youtube.com/watch?v=wW3PVG-o5JA
and in this one in particular at the 1:19 mark he mentions "The company's CMMC workstations are configured to prevent the copying of information from the Sharepoint environment to the CMMC workstation through security policies applied in the Edge browser."

So, this guy before has stated he isn't an "IT Guy" with some of the other videos and has made mention on one of the answers "through the IT department" as well as some other comments. I have never seen such a setting in Edge/Chrome. I HAVE seen that setting in Sharepoint as you can limit what users can do with the file (copy/paste, save, share etc.). Is that what he means and maybe doesn't understand there is a difference or am I missing something?

If you think Sysadmin would be a better sub for this question then I will do so instead.
