If your organization uses Microsoft Sentinel and/or Splunk (Cloud Platform or Enterprise) as a SIEM solution, you can configure Security Guardian to forward Findings to the applicable tool for further analysis.

You can also configure email alerts for Findings, as well as for the first completed assessment.

Once configured, the tile for the forwarding destination shows details of the configuration, as well as when the last Finding was sent. A forwarding destination can also be edited or removed.

To access the Forwarding configuration page:

1. From the On Demand left navigation menu, choose Security | Settings.

2. Make sure the Forwarding tab is selected.

To configure Microsoft Sentinel as a forwarding destination:

3. Click Send Test Event to ensure that a connection can be made to Sentinel.

   A message will be returned indicating whether or not the test event was successfully sent. If the test event was not successful, ensure the Workspace ID and Shared Key were entered correctly.

An indicator consists of a set of criteria that is used to evaluate collected data and generate Findings for:

• Tier Zero object activity
• The following Hygiene, Detected TTP, and Detected Anomaly indicators:

If you no longer want a Finding to be generated for an indicator, you can mute it.

A list of all indicators displays, with the following information for each:
