You can use this page to identify any sensors that have issues or errors, such as RFM, which is a mode that limits the sensor's functionality due to license expiration, network connectivity loss, or certificate validation failure.

Custom Alerts let you set up email alerts based on predefined templates that cover a wide range of topics including Real Time Response session initiation, host containment, OS security settings, and more that are not yet covered by notification workflows.
