🚨 The Signal: Teams users can now report security risks in external one-on-one, group, and meeting chats. This enhances threat intelligence gathering from external collaboration, improving incident response capabilities.

• Compliance teams can leverage enhanced reporting for audits.

The Action

1. Review existing incident response playbooks to incorporate this new reporting channel.

3. Monitor security reporting dashboards for increased volume or new types of external collaboration incidents.
4. Evaluate integration of Teams reporting with existing SIEM/SOAR solutions for automated triage.
