This article is intended for business customers. If you are a home user looking for information about Safe Links in Outlook, see Advanced Outlook.com security.

Office 365 Advanced Threat Protection (ATP) helps to protect your organization from malicious attacks by:

Protection through Office 365 ATP is determined by policies that your organization's security team defines for Safe Links, Safe Attachments, and Anti-Phishing. It's important to define policies, and to periodically review and revise those policies to keep them up to date and to take advantages of new features that are added to the service.

Reports are available to show how ATP is working for your organization. These reports can also show you areas where you might need to review and update your policies. And, if you have files that are marked as malware that shouldn't be, or files you'd like Microsoft to examine, you can submit a file to Microsoft for analysis.

New features are continually being added to ATP

We are continuing to add new features to Office 365, and that includes ATP. Below is a list of several new features, some of which call for an ATP policy to be reviewed and updated. To learn more about new features coming to ATP (or Microsoft 365 in general), visit the Microsoft 365 Roadmap.

Feature updates Action items
Beginning in February 2019 and rolling out over the next several months, Threat Intelligence capabilities are being added to ATP. In addition, if your organization does not currently have ATP, you'll have new options to consider, including ATP Plan 1 and ATP Plan 2. To learn more, see Office 365 Advanced Threat Protection plans and pricing and the Office 365 Advanced Threat Protection Service Description. Review your organization's subscription, and if needed, Buy or edit an add-on.
Beginning in October 2018 and rolling out over the next several months, when people are using Outlook or Outlook Web Application (OWA), ATP Safe Links renders original URLs, not rewritten URLs. (We call this native link rendering.)
When native link rendering is available for your organization, this feature will work in Outlook 365 (Click-to-Run) and OWA.

Get Office 365 ATP

Office 365 ATP is included in subscriptions, such as Microsoft 365 Enterprise, Microsoft 365 Business, Office 365 Enterprise E5, and Office 365 Education A5. If your organization has an Office 365 subscription that does not include Office 365 ATP, you can potentially purchase ATP as an add-on.

There are several kinds of ATP policies to define and periodically review.

  2. Set up ATP Safe Links policies in Office 365 including your organization's custom blocked URLs list and custom "Do not rewrite" URLs list.

  3. Set up ATP Safe Attachments policies in Office 365 and choose from several options, such as Dynamic Delivery and previewing.
