Does the provider see the fact that Tor is being used?

Question

Information Security

And if he sees, how to make him not see? VPN to raise to the input node of the torus?

Answer 1

Yes, they can see.
Use the built-in Tor mode, which is designed to bypass Tor traffic blocking, that's what it's called.
But this is an extra paranoia, you will be taken sooner or later anyway.

Answer 2

Then the provider will see the use of vpn, which in principle is also equivalent to using tor.
So don't worry, when you start hiding activity, they will see it. I would immediately hang an extended tracking protocol on such people - where he works, who he works for, expenses, earnings. To understand why this person can use the encryption of his traffic. According to the results, even total surveillance is possible.
