Collaboration Security for Microsoft Teams

The rise of collaboration tools like Microsoft Teams also represents a new attack surface for adversaries. Attacks like phishing and ransomware that for decades have primarily used email as an entry point, are expanding to target collaboration tools more frequently. While Microsoft Defender for Office 365 has been providing protection in Microsoft Teams at time of click, we are excited today announcing a preview of enhancements to that protection, further protect users in Microsoft Teams and enhance the Security operations flows.

NOTE: this preview is only available to Microsoft Defender for Office P2 customers.

Description of the feature set:

Building on the current Safe Links protections for teams we are adding, in preview, additional functionality to enable end users in Microsoft Teams to report suspicious messages, zero hour auto-purge (ZAP) for malicious items along with the relevant Security operations flows such as alerting, submissions and quarantine.

This message is associated with Microsoft 365 Roadmap ID 117595

When this will happen:

Public Preview: We will begin rolling out on late March and expect to complete by mid-May.

GA: We will begin rolling out late June 2023 and expect to complete by late July 2023.

How this will affect your organization:

Teams Admins, SecOps and End Users will see new added experiences in Teams Admin Center, Security Console and Teams Client (web and desktop) respectively for the following features:

• Enhanced visibility into the attack landscape through end-user reporting
• Effectively Respond with Post Delivery Analysis, ZAP & Quarantine
