School installs certificate using 3rd party program to connect to their internet. How safe am I?

My school uses a service called [secureW2](https://www.securew2.com/)to install a certificate on devices that want to connect to the internet. I am concerned about my privacy. Can they see what I am doing when I am not on one of their access points?

I used the software on a different user on my windows computer and can connect to the internet from there, but sometimes I need to access the internet on the main user.

Is my university getting *any* info …
