Hi @nhussaini,
An (alert) exclusion is used to suppress alerts that are of no value, while a (rule) exception is used to tune rules in protection modules that detect, prevent, and generate alerts within Cortex XDR.

Hi @nhussaini,
Alerts caught by exclusions are prevented from being created in the Cortex XDR tenant, keeping it from being seen in the alert table or being attached in an incident. The data for the alert is still available in the QueryBuilder.

Can Alerts that are filtered by exclusions be retrieved?

Hi @MP18,
No, alerts that are filtered by exclusions cannot be recovered within the Cortex XDR tenant. Depending on your version of the Cortex XDR Agent, you can look at the events tab in the console to see recent alerts, however.

Can you create an exclusion rule from an alert?
Regards
Hi @MP18,
No, any alert you exclude from the quick menu in the alert will only create exclusion by alert id.

Should we use exclusion with all alert sources as first response?

Hi @MP18,
No, as a recommendation, if there is a way to fine-tune the alert without exclusion, that will be preferred. For example, BIOC/IOC - Rules tunning, Malware/Exploit - Support exception or profile tunning.
