Is it possible to determine the use of TOR?

Question

Anonymity

Good day!
Who can tell if the VPN channel admin can somehow see the use of TORa from the inside to the outside, being in the corporate network? If so, how?

Answer 1

Make a list of GCD and already see where the traffic goes.

Answer 2

I read an article about traffic detection through the search for "cunning" certificates at the beginning of a TLS session. They are really unusual for TOR.
