How to ensure complete anonymity on the Internet?

Question

Information Security

We need complete anonymity on the Internet so that no one, no one! No third party found out about my communication with the PC)))

Answer 1

Complete anonymity can only be ensured by not using the Internet :) Yes, you can buy a VPN abroad - but the provider will still have the fact of connecting to the VPN in the logs. Yes, you can install Tor - but in the same logs, the fact of exiting to Tor will still remain. Yes, there will be no content there - but the metadata that the action was performed may be enough to apply thermorectal cryptanalysis, during which you yourself will voluntarily and with a song tell where and why you went.
To begin with, form a model of the intruder - from whom do you want to protect yourself? If from the state, then it is useless, the state is able to become a global observer and it has enough resources. Can be complicatedthe process of obtaining information, but it is impossible to think over some mechanics to do one, two, three - and one hundred percent anonymity is guaranteed.
If we are talking about a corporate network, then there is no anonymity by definition.
