Detection section
The following section provides information for those who wish to learn more about the detection capabilities enabled by collecting this intake. It includes details about the built-in rule catalog, event categories, and ECS fields extracted from raw events. This is essential for users aiming to create custom detection rules, perform hunting activities, or pivot in the events page.
Event Categories
The following table lists the data source offered by this integration.
| Data Source | Description |
|---|---|
Email gateway |
Retarus Email Security solution. |
In details, the following table denotes the type of events produced by this integration.
| Name | Values |

| Kind | alert |
| Category | email, malware, web |
| Type | info |
Transformed Events Samples after Ingestion
This section demonstrates how the raw logs will be transformed by our parsers. It shows the extracted fields that will be available for use in the built-in detection rules and hunting activities in the events page. Understanding these transformations is essential for analysts to create effective detection mechanisms with custom detection rules and to leverage the full potential of the collected data.
