The Quarantine compliance rule quarantines the email that contains sensitive data.
Important
You must configure this rule only if you wish to use the quarantine automated action.
In the Nightfall UI, navigate to Integrations from the left navigation bar and click the Manage button for the Gmail integration.
All the headers and expressions required to create the compliance rules are available in the Installation section under Gmail settings as displayed in the image below. Keep this screen open to copy/paste the headers as you create the content compliance rules in Google Workspace. We will refer to this page as the Gmail settings page throughout the document.
Navigate to the Compliance page of the Google Workspace (ignore this step if you are already there else refer to steps 1-6 of the Create Content Compliance Rule - Monitoring document to navigate to the compliance section).
Scroll down to the Content Compliance section and click ADD ANOTHER RULE. (If you have not created any Compliance rule previously, the button might be displayed as CONFIGURE).
Enter a name for the compliance rule ("Quarantine Rule" is added as the name in this document).
Select Outbound and Internal - Sending checkboxes in the Email messages to affect section.
If you select only the Outbound check box, only those emails that are routed out of your organization to external domains, are scanned. If you wish to scan internal emails (emails that are sent between the employees of your organization). you must select the Internal - Sending check box.
Select the If ANY of the following match the message option.
Click Add.
In the Add setting dialog box, select the Advanced Content match option.
In the Location drop-down menu, select Full headers.
In the Match type drop-down menu, select Contains text.
Navigate to the Gmail settings page on the Nightfall UI and copy the value from the Header field, located under the Quarantine Content Compliance Rule (Optional) section.
Return to the Google Admin Workspace window and paste the copied value in the Content field. Nightfall updates the headers for all emails that need to be quarantined with “x-nightfall-quarantine”, once they are processed and before they are routed back to Gmail. This enables Gmail to quarantine the emails with this header.
Click SAVE.
In stage 3, select Quarantine message.
(Optional) Select the Notify sender when mail is quarantined check box to notify the sender when their email is quarantined.
Click SAVE.
