Download Tor on your personal computer
Visit the clearnet site from Tor
Or you can go to the onion site via Tor
Sites are in the Globals
Your ISP will know you connected to Tor but they will not know where you went
I work for a Fortune 500
And we have trouble getting conformed data across our own damn systems
Unless you are in a bleeding edge tech firm
Or a spoopy firm with a ton of monitoring and controls around employees because of what your company does
You are safe
