Office 365 Advanced Threat Protection
Office 365 Advanced Threat Protection (ATP) helps to protect your organization from malicious attacks by:
Scanning email attachments with ATP Safe Attachments
Scanning web addresses (URLs) in email messages and Office documents with ATP Safe Links
Identifying and blocking malicious files in online libraries with ATP for SharePoint, OneDrive, and Microsoft Teams
Checking email messages for unauthorized spoofing with spoof intelligence
Detecting when someone attempts to impersonate your users and your organization's custom domains with ATP anti-phishing capabilities in Office 365
Protection through Office 365 ATP is determined by policies that your organization's security team defines for Safe Links, Safe Attachments, and Anti-Phishing. Reports are available to show how ATP is working for your organization. And, you can submit suspicious files to Microsoft for analysis.
Office 365 ATP is included in subscriptions, such as Office 365 Enterprise E5 and Office 365 Education A5, and, as of April 30, 2018, also Microsoft 365 Business security features. 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.
Get Office 365 ATP
As a global or security administrator, go to https://portal.office.com and sign in with your work or school account for Office 365.
Choose Admin > Billing to see what your current subscription includes.
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.
Define policies for ATP
Set up ATP anti-phishing policies in Office 365 including impersonation-based attacks to protect against attackers who send email messages that appear to be from trusted people or domains
See how ATP is working by viewing reports
After your ATP policies are in place, reports are available to show how the service is working.
Make sure that you are an Office 365 global administrator, security administrator, or security reader. (See Permissions in the Office 365 Security & Compliance Center.)
If needed, make adjustments to your security policies. See the following resources:
