session end reason "Threat" for url blocked log

Firewall is showing session end reason as 'Threat' in traffic logs for the traffic blocked under url filtering profile. this is really causing lot of noise in our SIEM tool. how can i remediate this?

thanks.

@SThatipelly,

You need to modify the filter on your log-forwarding profile that is sending these logs to your SIEM. An example filter would be the following:

not (session_end_reason eq threat) and (zone.src eq Trust) and ((category eq URL-List) or (category eq proxy-avoidance-and-anonymizers))

Or tune your SIEM to not alert so much?
