Create information barriers in Slack

By default, any member of an Enterprise Grid organization can send direct messages (DMs) and call any other member in their organization. To prevent specific members from sending DMs or calling each other, you can create information barriers between IDP groups. This allows your organization to avoid conflicts of interest and safeguard sensitive information.

What to expect

  • Members will see a message informing them of an information barrier in any conversations they’re barred from participating in.
  • Any existing DMs will become read-only when an information barrier is created between any members in the conversation. New DMs and Slack calls will be blocked if two or more participating members have a barrier between them.
  • Groups you’d like to create barriers between must be configured in your IDP before you create an information barrier in Slack.
  • If members of IDP groups with a barrier between them are in the same workspace or some of the same channels, they may still be able to interact in public and private channels.
