Do the Penetrator Support Multiple User login?

Yes

You can create multiple users on the Penetrator with different access.

How can cloud user benefit me?

So let say they have 3 administrators.

The main manager create 1 account for each.

So example administrator 1 has responsibility for 192.168.1.0/24

another for 10.10.10.0/24 then each can their own permission and own account only with their task.

It can also be you have your own Penetrator as a partner.

And you offer monthly cloud scanning to your customers.
