On the Remediations page, Administrators and Analysts can see a summary of all remediated indicators, create bar and pie charts, and complete manual actions for multiple hosts. To highlight the severity of remediated threats, the Remediations page shows the previous score, which is the original score of the indicator before it was remediated. Observers can only view the page.
From the TDR Dashboard, you can use the Indicator Timeline to see a timeline of resolved indicators. Click the bubble for a resolved indicator to go to a filtered view of the Remediations page. For more information about the Indicator Timeline, see TDR Dashboard.
You can also select ThreatSync > Remediations to go directly to the Remediations page.
Remediated Threat Counts
By default, the top of the Remediations page shows Remediated Threat Counts. This chart is a visual summary of all remediated indicators in the system. Remediations are categorized based on the previous scores assigned to the indicators before remediation. The number and size of each bubble indicates the total number of remediated indicators with previous scores in each category.
- Critical — Scores of 8, 9, or 10
- High — Scores of 6 or 7
- Medium/Low — Scores of 3, 4, or 5
Remediated Threat Counts include all remediations in the system. These counts do not change based on the filters set on the Remediations page.
To show the Remediated Threat Counts summary after you generate another chart, click .
When you select ThreatSync > Remediations, the filters on the Remediations page are set to show indicators with a previous score of 6 or higher that were remediated within the last 24 hours. Use the column headings to clear or change the filters.

The Remediations list shows a list of indicators with status information and requested actions. The same indicator can appear on the list multiple times, once for each action. This makes it easy to see all actions for each indicator.
For each indicator, the Remediations list includes this information:
- Previous Score — The previous score assigned to an indicator before a remediation action was completed.
For more information about threat scores, see About TDR Threat Scores.
- Source — The source of the indicator: Host Sensor () or Firebox ().
- Indicator — The indicator details. You can filter this column by indicator type, as described in the next section. To see more details, click Additional Info. For information about indicator details, see Manage TDR Indicators.
- Host/IP — The host name or IP address of the host system.
- Action Requested — The action recommended by Threat Detection and Response for an indicator from a Host Sensor.
- Outcome — Indicates the remediation action taken, if any. To see the action log and remediation history click .
- Operator — Indicates which user completed a remediation action. If Threat Detection and Response completes an action, the user is System.
- Action Date — The date and time the action was completed.
- Remediation Date — The date and time the remediation action for this indicator was completed.
For information about which actions can remediate an indicator, see TDR Remediation Actions and Threat Scores.
On the Remediations page, you can select these actions for selected indicators:
This action adds this indicator to the Whitelist as a known safe file or process. When you select this action, a whitelist signature override is created with the MD5 value of the indicator. For more information about the Whitelist, see Configure TDR Signature Overrides.
This action removes a file from quarantine. When you remove a file from Quarantine, the file is automatically added to the Whitelist.
This action removes all files related to a Host Ransomware Prevention (HRP) action from quarantine. Files removed from Quarantine are automatically added to the Whitelist.
For more information about actions to remove a file from quarantine, see Remove a File from Quarantine.
After you select one of these actions, the indicator is no longer considered a threat and is removed from the Remediations page.
