Microsoft Office 365 Security: ATP Gains Automated Incident Response

Automated Incident Response capabilities are now available for the Microsoft Office 365 Advanced Threat Protection (ATP) cloud-based email filtering service. Security teams can apply these capabilities to investigation and response workflows.

Two categories of Office 365 ATP Automated Incident Response capabilities are available:

  • Automatic: Triggered when an end user reports a phishing email or clicks a malicious link, malware is detected after an email is delivered or a phishing email is identified when it reaches a user’s inbox.
  • Manual: Triggered from within Office 365 APT’s Threat Explorer tool at any time for any email and related content (attachments or URLs).

Office 365 ATP Automated Incident Response is available via Office 365 ATP Plan 2, Office 365 E5 and Microsoft 365 E5 Security.
