Web filtering - Certificates errors

Hi Axel Rouge 

HTTPS scanning works with the certificate to scan and block the content filter as applied in the firewall and you required to import the certificate for the "certificate error" issue.

By "import" you mean on the client device right or am I missing something ?

I can't go on each device as there is around 400 of them and they change almost everyday as the users bring their own devices.

Isn't there a way to only do URL filtering without scanning the HTTPS content ?

Thanks for the link, it's way more clear now :)

We decided to drop the HTTPS connections that are blocked by the Webfiltering.
