Shared channel (beta) security & policies

Beta: Shared channels is a completely new feature in Slack, currently in the beta phase. Learn how to join Slack's shared channel beta.


Keeping your account secure, protecting your privacy, and building a service you can trust are our top priorities at Slack.

Shared channels let two separate workspaces communicate securely in Slack, so we’ve taken extra precaution to design and build a feature that allows your team to work safely and efficiently with other people.

💡  For details about this feature, read how to create a shared channel on your workspace.

 

The basics

Creating a shared channel

For two organizations to start sharing channels, both workspaces must agree to use the feature. A Workspace Owner or Admin on one side must send a request, and a Workspace Owner or Admin on the other side must accept it. Only Workspace Owners and Admins can agree to share channels with other workspaces.


Accepting a shared channel invitation

If you're a Workspace Owner or Admin, any invitation to share a channel with another workspace will go directly to you. An invitation to share a channel with another workspace will include which organization it’s from, the sender’s email address, and sometimes will have a message with more information. You can use this info to identify the sender and the organization they’re a part of, and find out if anyone from your workspace is working with them.

If, despite this, you’re not sure what the shared channel is for and who they are, don't fret! You have a few options:

  • Don't accept the invitation. You’re not required to share channels with this other workspace. You can simply decline the invite and your organization won’t share channels with theirs.
  • Email the sender for more information (their email address is included in the invitation you received.
  • Ask your team. If someone from your workspace is partnering with another workspace, they'll be able to give you more information.

 

Policies and functionality during the beta period

Read the information below* to learn more about which features and functionality are available during the beta period, and what you can expect once shared channels is fully launched.  

 

🔏  Custom message and file retention policies

  • Beta 
    Custom retention policies aren’t supported for shared channels during the beta period. All messages and files sent in shared channels, and within direct messages related to shared channels, will be set to the default message retention setting — 
    Keep all messages.

  • After the beta
    Custom retention policies will be supported. This means each organization can have different message and file retention policies in place for shared channels.

    For example, Workspace A’s policy is set to keep all messages and Workspace B’s policy is set to keep messages for 30 days. Workspace A will be able to see all messages in a shared channel and Workspace B will only see messages from the last 30 days.

 

🔏  Message editing and deletion permissions

  • Beta 
    Editing and deletion privileges work the same way that your workspace’s settings apply to you and your workspace’s messages.

    For example, a Workspace Admin can delete messages sent by members of their workspace, but not messages sent by members of another.

  • After the beta
    No changes in functionality.

 

🔏  Compliance Exports and Discovery API

  • Beta 
    For workspaces with Compliance Exports or Discovery APIs turned on, exports will include messages and files from public and private channels, shared channels, and direct messages.

  • After the beta
    No changes in functionality.

 

🔏  Data Leak Protection (DLP)

  • Beta
    DLP will not apply to shared channels during the beta period.

  • After the beta
    Both workspaces will be able to read the content — or data — posted in shared channels, but writing or editing the data is limited to the workspace that sent the data.
