Quarantine for Review

<PlanAvailability slug="entry-adv" />

Every Mattermost user contributes to data security. From Mattermost v11.1, you can help keep your workspace secure and prevent data spillage by quarantining messages that may contain sensitive or restricted information for review by authorized moderators. Your quick actions can prevent accidental leaks before they spread, and build a culture of shared responsibility for secure communication.

Quarantine a message

For example, you notice a public post in a channel that contains internal project details that not all users should have access to. You can quarantine that message as Sensitive data to alert designated content reviewers right away.

1. Hover over the message, select the More actions icon, and then select Quarantine for Review.
2. Select a reason for quarantining the message, and add a comment explaining why you're quarantining it, when required.
3. Select Submit.

You’ll see a confirmation that your message was quarantined. Mattermost may hide the quarantined message based on how your system admin has configured Data Spillage Handling workflows. You can’t quarantine the same message twice.

If your message is quarantined

A message being quarantined isn’t a disciplinary action. Quarantined messages help to protect sensitive data across your organization.

If another user quarantines one of your messages, you’ll receive a direct message from the Data Spillage Bot explaining which message was quarantined and why. If Mattermost has hidden your message, the direct message won’t contain the quarantined message content.

You'll receive another direct message once reviewers take action.

• If your message is removed, review the reason why it was quarantined, and adjust how you share information in the future.
• If your message is kept, no further action is required of you.

Contact your reviewer or system admin if you need clarification about actions taken or next steps.
