Abstract

Cortex XDR Legacy Exception rules enable you to configure an exception to prevention and protection modules on endpoints for selected profiles.

Legacy Exception rules enable you to configure an exception to prevention and protection modules on endpoints for selected profiles.

Items included in allow lists continue to generate Cortex XDR security events. If you want to exclude event reporting as well, configure this on the Alert Exclusions page (SettingsException ConfigurationsAlert Exclusions).

Prior to Cortex XDR version 3.5, Legacy Exceptions were configured through profiles.

Starting with version 3.5, Cortex XDR enables you to manage the Malware Security exceptions from a central location and easily apply them across multiple profiles in the Legacy Agent Exceptions Management page. 

To manage the prevention profile exceptions from Exception Configuration, you must first migrate your existing exceptions configured via the Prevention profiles.

Your migrated rules are displayed on the SettingsException ConfigurationsLegacy Agent Exceptions page. For more information about the migration, see Exception Configuration.
