Security for Google Groups for Business

The Google Groups for Business service provides multiple options for securing the groups in your domain. With full control over all groups for administrators, along with user-level control, the service is also flexible, so you and your users can choose the right level of security for your groups.

Administrator control

As a Google Apps administrator, you have control over what users can do with the Google Groups for Business service and all of the groups they create.

Sharing settings

To provide security for your entire Google Groups for Business service, you can set sharing options to:

  • Prevent people outside your domain from accessing your Groups service
  • Prevent users from creating their own groups
  • Identify all user-created groups with a special suffix in the group address
  • Prevent users from adding external addresses to the groups they own
  • Prevent users from allowing external messages to be sent to the groups they own
  • Let users keep their groups out of the Groups directory

Group settings

To ensure the security of a specific user-created group, you can:

  • Change an owner or manager to a regular member
  • Add or delete members
  • Change any of the access, delivery, archive, and other settings
  • Delete it
Note: If you change any of a group's settings, another owner or manager can change the settings again. To prevent changes to your settings, you can change owners and managers to regular members. That way, only you (the administrator) can manage the group and ensure its security.
User control

To provide security for their groups, users who are group owners or managers can:

  • Specify who can send messages to the group, view the group archive, and view members in the group
  • Specify who can join the group
  • Prevent members from inviting others to join the group
  • Moderate messages sent to the group
  • Prevent messages to the group from being archived
  • Prevent people outside your domain from being members of the group (if you select the sharing setting that lets users add external members)
  • Prevent people outside your domain from sending messages to the group (if you select the sharing setting that lets users allow external messages)

Users who are group owners can also:

  • Change another owner or manager to a regular member
  • Delete their groups
