Hornetsecurity on Thursday reported that 45% of Microsoft Teams users surveyed frequently send out confidential and critical information on the platform and 51% send business-critical documents and data via Teams.

The survey also found that 48% of all respondents sent messages on Teams they should not have. Of this group, 88% had been trained on how to use collaboration solutions. This highlighted the need for increased and improved training on how to use Teams and the risks of sending sensitive data.

Some 70% of respondents also exchange more direct messages with colleagues via user chats in Teams as opposed to group channel conversations, which Hornetsecurity researchers said pointed out the need for security pros to stop overlooking backup and security for user chats.
