Without the Threat Prevention blades, no.
The Threat Prevention blades do provide an important signal here. Using the data from a lot of other customers run through machine learning, we are able to identify potentially malicious traffic patterns.
While this ultimately does inform the Threat Prevention intelligence sent to your gateways, we have a service coming soon that will leverage this intelligence in a new way, helping you to easily pinpoint the source of the problem with high confidence. We plan to launch it in the near future.
@Oren_Koren can tell you more if you're interested.
