Email alert when a domain is no longer accessible

Hi Skoberg,

Thanks for the question!

So I would kindly suggest you raise an RFE for this, as we do not have this functionality supported in Cato.

As a potential workaround, you could ensure your firewall rules are configured to enable events and notifications (of course, be aware that this could create some further overhead).

So if traffic becomes blocked because it no longer matches your respective custom app (as in you're use case, because the domain IP changed). The traffic should match another rule or even a block rule, and you should see this in your events, or email notifications.
