I work on a corporate laptop that has an infamous root CA certicate installed, which allows the company to intercept all my browser traffic and perform a MITM attack.

Ideally, I’d like to use the company laptop to read my own mail, access my NAS in my time off.

I fear that even if I configure containers on that laptop to run alpine + wireguard client + firefox, the traffic would still be decrypted. If so, could you explain how the wireguard handshake could be tampered with?

What about Tor in a container? Would that work or is that pointless as well?

Huge kudos if you also take the time to explain your answer.
