This stage allows you to select notification channels if a policy violation occurs. The notification alerts are sent at two levels.
The steps to configure alert channels for policy-level integration are the same as in the case of integration-level alerts. You can refer to for steps.
Automated actions allow you to configure automated remediation actions when sensitive data is found in an Email. Nightfall supports two automated actions for Gmail DLP.
Block: The Block action blocks the Email and prevents it from being sent to the recipient. The sender receives a notification email that states that their Email was not sent to the recipient.
Quarantine Email: The quarantine action guarantees the email which has sensitive data. A Nightfall admin can review the quarantined Email to check if data is sensitive and then take a call as to whether the Email must be sent to the recipient or blocked permanently.
Encrypt Email: The encrypt action securely encrypts the contents of the email. When the encryption action is applied a new Event is created in the Nightfall Encryption Events page.
If you enable the encryption action, additionally you can also configure the expiration time for the email. The recipient cannot view the email after the expiration of the time.
If you do not enable any of the automated actions, the Email with sensitive data is sent to the recipient. Nightfall recommends that you enable at least one of the automated actions.
Conflicts can arise in two main scenarios:
All the automated actions are configured in a single policy.
Multiple policies with different automated actions were violated simultaneously within the same file, message or record.
When conflicts occur, Nightfall implements the most severe automated action. The priority order to manage conflicts in Gmail is as follows.
Encryption
Block
Quarantine
If you create three policies and enable the encrypt action in first policy, Block in second policy, and Quarantine in the third policy, and if all of the 3 policies are violated, in this case, the encrypt action is enabled on the Event (and not Block or Quarantine).
Also, if you delete the first policy in which the encrypt action is enabled, and then if both the remaining policies are violated, the Block action is enabled (and not Quarantine).
If you enable all the three actions in a single policy, and if the policy is violated, the encryption action is applied.
This section allows you to configure notifications to be sent to the end user whose actions triggered the violation.
The automation settings allow you to send notifications to end users. You can select one or both the notification methods. You must first turn on the toggle switch to use the automation option. The automation notification channels are as follows
Email: This option sends an Email to the user who sent the email with sensitive data.
Slack: This option sends a Slack message to the Gmail user who sent the email with sensitive data.
End-user remediation (also known as Human Firewall) allows you to configure remediation measures that end users can take, when a violation is detected on their Gmail Emails. You must turn on the toggle switch to use this option. End-users receive the remediation actions in an Email as an action item. The available actions in that Email depend upon the actions that you select in this section. The various available remediation actions for end-users are as follows.
Report as False Positive with Business Justification: This option allows end users to report false positive alerts and provide a business justification as to why the alert is considered to be false positive.
Report as False Positive: This option allows end users to report false positive alerts.
When end-users report alerts as false positive, you can choose the resolution method to be either Automatic or manual.
If end-users do not take any remediation action, you can set the frequency at which they must receive the notifications to take action.
To learn more about how automated actions impact the end-user and Nightfall admin, see .
Enter a custom message to be sent to the end user. This message is sent in an Email. You can modify the default message provided by Nightfall and draft your message. The total character length allowed is 1000 characters. You can also add hyperlinks in the custom message. The syntax is <link | text >. For example, to hyperlink with the text Nightfall website, you must write < | Nightfall website>.
