Can ISPs monitor traffic?

Question

VPN

Can ISPs, VPNs, Proxy servers monitor traffic?
I think SSL protects against such?
For example, I log in to the site and can these intermediaries see all my messages / traffic?
I am concerned about my privacy.

Answer 1

What does my provider know about me?

Answer 2

Of course they can. And they do it all the time, but in some places (in the Russian Federation, for example), they are obliged to do it :) (providers).
Of course, ssl protects, but... there is such a thing as bumping :) and due to the ubiquitous ssl-ization, I think we will see its widespread use nationwide very soon. If the provider/VPN/proxy requires a certificate for whatever reason to get started, it will definitely bump it :) If not, they can write logs, which may also be interesting for certain people...
