How to stop that? It consumes alot of internet data

nsurlsessiond is the process that is used by iCloud to sync your iCloud Drive/Photos/Contacts/etc between your mac and the iCloud server.

You can try signing out of iCloud and back in again

Sign out of iCloud on your ..Mac...

It seems that you have one or more apps using a lot of bandwidth. Use the Activity Monitor (Applications > Utilities) and click on Network to see which apps are responsible for this. Note that you can sort the data in the columns by clicking on their headers.

You are correct: the 1st culprit could be iCloud. But, from what I understand, this process is also used to handle data transfer for other apps.

And please do correct me if I am wrong: I'm still learning...
