i need to prevent all downloads on a network using Palo alto without affecting browsing
i created a file blocking profile , denied all extentions in the download direction and applied it in a policy
but iam still able to download many exe and jpeg for example
i dont have a decryption policy in place
is it necessery ??
In this case it would be since you need visibility into the traffic to see what's actually being done. If you take a look at what you've been able to download you'll likely see all of the traffic getting identified as 'ssl'; since you aren't decrypting this traffic the firewall can't see what your client is downloading.
