Event rules Event rules let you automate reactions to supported device events. Open Dashboard → Event rules to create rules that watch enrollment, disenrollment, non-compliance, and Android geofence events, then trigger one or more actions automatically. What an event rule can do Each rule combines a subject , an event , and one or two actions . Supported subjects are All devices , Specific device , and Policy . Events : device enrolled, device disenrolled, device becomes non-compliant, geofence enter, geofence exit. Device actions : disable device, enable device, lock device. Email action : send a notification email to administrators and, when enabled, delegated managers. A rule can contain an email action only, a device action only, or one device action plus one email action. If both actions are configured, Cerberus Enterprise executes the device action first and the email action second. Platform and compatibility rules The available events and actions depend on the selected subject and on the platform that applies to that subject. Android supports enrollment, disenrollment, non-compliance, and geofence events. Apple supports enrollment, disenrollment, and non-compliance events. Disable device and Enable device are Android-only actions. Lock device and Send email are available on both Android and Apple, when the selected event supports them. Device disenrolled supports email only. Rules list The Event rules list is the main management page for this feature. It includes a searchable table with rule name, subject, event, actions, platform, enabled state, and update time. Use the filter chips to switch between all rules, enabled rules, disabled rules, and text search. Use the Refresh button to reload the current table view. Use the enable switch in each row to temporarily enable or disable a rule. Use the multi-row selection mode to delete several rules together. Use Create event rule to open the editor for a new rule. Rule editor The editor is divided into General , Scope , Trigger , and Actions sections. At the bottom of the page, a sticky action bar keeps the main buttons visible while you scroll. General Name : required, up to 150 characters. Description : optional, up to 2000 characters. Rule enabled : saves the rule in enabled or disabled state. Scope The scope defines which devices the rule can match. The editor also shows the resolved platform and, when available, the effective policy context. All devices : the rule can match all supported devices in the enterprise. Specific device : select one managed device from the picker dialog. Policy : select one policy template from the picker dialog. Trigger The trigger section filters available events automatically based on the selected scope and platform. Geofence triggers Geofence enter and exit rules are supported only for Android and require a valid Android policy context. For location reporting and geofence definitions, see Location and geofence . If the subject is All devices , the rule always applies to Any geofence . If the subject is a device or policy, you can choose Any geofence or one Specific geofence . The specific geofence list is loaded from the effective policy context of the selected device or policy. Actions The actions section lets you choose an optional device action and an optional email notification. The UI hides unsupported combinations automatically. If no device action is available for the selected event and scope, you can still save an email-only rule. If email is disabled for the selected event and platform, the email toggle is unavailable. A rule without any action is invalid and cannot be saved. Email recipients Email actions always include enterprise users with the ADMIN role. If the enterprise is managed through multi-tenancy, you can expand recipients to include MT managers. Main managers only : includes enterprise admins and the main MT manager contacts. Main managers and sub-account managers : adds assigned sub-account managers too. The preview list shows the actual email addresses that will be used when the rule runs. Only delegated managers with granted access to the enterprise are included in the final recipient list. Execution behavior Event rules run immediately when Cerberus Enterprise receives a supported event from the backend integrations. Disabled rules are skipped automatically. Successful and failed executions are recorded in the system log with human-readable messages.
