Problem with blocking a application

[George]

Hy !

I have a problem with a user accessing an application that I restricted settings on firewall 90d

On application control i block the cloud IT option, but my user succed to bypass this settings and connect to different website

How to i block this user on other ways to visit different cloud IT applications ?

You may have different options available, but without knowing what firmware your 90D is running, it may be guess work here and without knowing more about how the firewall rules/app sensors are setup.

Just remember that firewall rules (and app sensors) are processed from top-to-bottom.  So your "block Cloud IT" app sensor should be placed in a firewall policy rule that is high up (in a app sensor policy) and any general firewall policy rule, so that it gets triggered.
