Office 365 Advanced Threat Protection

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 periodically review and revise your 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.

Get Office 365 ATP


Office 365 ATP is included in subscriptions, such as Microsoft 365 Enterprise, Office 365 Enterprise E5, Office 365 Education A5, and Microsoft 365 Business. If your organization has an Office 365 subscription that does not include Office 365 ATP, you can potentially purchase ATP as an add-on. For more information, see Office 365 Advanced Threat Protection Service Description.

  1. As a global or security administrator, go to and sign in with your work or school account for Office 365.

  2. Choose Admin > Billing to see what your current subscription includes.
    As a global admin, sign in at and go to Admin > Billing

  3. If you see Office 365 Enterprise E5, Office 365 Education A5, or Microsoft 365 Business, then your organization has ATP.
    If you see a different subscription, such as Office 365 Enterprise E3 or Office 365 Enterprise E1, consider adding ATP. To do that, choose + Add subscription.

Once you have ATP, the next step is for your security team to define policies.
