Is it possible to set up a proxy to restrict access to google services?

Question

linux

There are several working machines in the office, all work with documents is done through google disk on a corporate account.
It is necessary to make sure that access to Google drive is only in the office.
Support wrote that you can configure a proxy for this.
I present several solutions:
1) use some kind of proxy provider
2) rent a server and configure nginx
3) configure a router (zyxel)

The first option is unsafe, in my opinion (even if we consider a paid proxy provider).
I consider the second option to be safer, because. have access to the server.
The third option is more attractive in terms of budget and locality of the solution, but it is not clear whether a white ip is needed for this, and how you will have to conjure with a router.

On the Internet, they mainly write about proxy / vpn settings in order to bypass the blocking of services, but so far I haven’t really found anything about this example. Itself not the network manager and not the administrator so I will be glad to council!

Answer 1

No way. Or move from Google Drive.
The 1st method does not work, because having a login-password a person will go to GDrive from anywhere
2nd method does not work, because having a login-password a person will go to GDrive from anywhere 3rd method does not work, because having a login-password a person will go to GDrive
from anywhere GDrive
There is no way to configure ip-restrictions in GDrive itself - if you need to restrict, use your own solutions (owncloud, nextcloud)

Answer 2

In order to prohibit a person from using GDrive, let's say at his home - you need to administer his home computer :)
Or configure access in GDrive itself, and if it is not there (restrictions) - use another provider.
