The Content Sharing data card shows the following information.

• Public Links -- The total number of public links found across file storage cloud applications. A public link is any link that the general public can access without requiring a login. Public links are easy to share and are not secure. If they link to content that contains sensitive information (for example, references to credit card numbers), that information could be exposed to unauthorized users, and could compromise the privacy and security of that data.
• The Remove Public Link option provides you with the flexibility of enabling information sharing but also allows you to protect specific types of content. When you create a policy, you can specify public link removal if a public link is included in a file with sensitive content. You can also specify removal of public links from folders that contain sensitive information.
• External Sharing -- The number of activities in which content is shared with one or more users outside the organization's firewall (external collaborators). If a policy allows external sharing, a user can share content (for example, a file) with another user who is external. Once content is shared, the user with whom it is shared can continue accessing the content until that user's access is removed.
• Protected -- The total number of events for which the public link or an external collaborator was removed. An external collaborator is a user outside the organization's firewall with whom content is shared. When an external collaborator is removed, that user can no longer access the content that was shared.
