USM Anywhere enables you to make the sensor Sensors are deployed into an on-premises, cloud, or multi-cloud environment to collect log and other security-related data. This data is normalized and then securely forwarded to USM Anywhere for analysis and correlation. drops future events Any traffic or data exchange detected by AT&T Cybersecurity products through a sensor, or through external devices such as a firewall. that match the rule. These events will be neither correlated nor stored. Through these rules, you can define which event data you are going to store in USM Anywhere. You will pay for the data you use.

Note: Filtering rules is not retroactive. The rule applies to future items, but not to to previous items, even if those items follow the rule.

Important: You can't use a correlation list when you create a filtering rule.
