not possible !? - Block all access to the internet except for a few specified websites

[scenarist]

Hello everyone,

What is the most effective method to block all outgoing internet traffic except for a few specified websites?

I've configured outbound firewall rules to permit access to a few specified websites. All other connections are blocked with a last outbound clean-up rule. However, this setup has led to a significant problem with slow loading of the allowed web pages.

I understand that there are external resources that allow web pages to be accessed, but is there any solution to fix this issue?

Alternatively, is there another configuration method to "block all outbound traffic except for a few websites" and avoid the slow loading of allowed web pages?

I find it hard to believe that there is no solution to this problem. I have tried many different client versions, but in vain.

Thank you.

I am using harmony endpoint and I don't know how to create one custom application with all the URLs  like on link above. Is that possible at all on harmony endpoint?
