Updated: Jun 7

Microsoft Office 365 Advanced Threat Protection (ATP) is a cloud-based email filtering service that helps protect your organization against unknown malware and viruses by providing robust zero-day protection, and includes features to safeguard your organization from harmful links in real-time.

What is Office 365 Advanced Threat Protection?

Microsoft is running this on a very large scale worldwide.

Besides Office 365 ATP, there are also other ATP products provided by Microsoft :

All of these products share information with each other using the Microsoft Intelligent Security Graph. By doing so, optimal integration is achieved, allowing different applications connected to this Security Graph to share information with each other.


ATP is included in Office 365 Enterprise E5, Office 365 Education A5, and Microsoft 365 Business.

  • Automatic Incident response

Safe Attachments

ATP Safe Attachments protects against unknown malware and viruses and provides zero-day protection to safeguard your messaging system. All messages and attachments that don’t have a known virus/malware signature are routed to a special environment where ATP uses a variety of machine learning and analysis techniques to detect malicious intent. If no suspicious activity is detected, the message is released for delivery to the mailbox.

Safe Links

The ATP Safe Links feature proactively protects your users from malicious URLs in a message or in an Office document. The protection remains every time they select the link, as malicious links are dynamically blocked while good links can be accessed.

Safe Links is available for URLs in the following apps:

  • Office 365 ProPlus on Windows or Mac

  • Office for the web (Word for the web, Excel for the web, PowerPoint for the web, and OneNote for the web)

  • Word, Excel, PowerPoint, and Visio on Windows, as well as Office apps on iOS and Android devices

  • Users must be licensed for ATP*, must be included in ATP Safe Links policies, and must be signed in on their devices for protection to be in place.

ATP for SharePoint, OneDrive, and Microsoft Teams

ATP for SharePoint, OneDrive, and Microsoft Teams helps detect and block files that are identified as malicious in team sites and document libraries.

Anti-phishing policies

ATP anti-phishing checks incoming messages for indicators that a message might be a phishing attempt. When users are covered by ATP policies (Safe Attachments, Safe Links, or anti-phishing), incoming messages are evaluated by multiple machine learning models that analyze messages and the appropriate action is taken based on the configured policies.

Real-time reports

Monitoring capabilities available in the Office 365 Security & Compliance Center include real-time reports and insights that let your security and compliance administrators focus on high-priority issues, such as security attacks or increased suspicious activity. In addition to highlighting problem areas, smart reports and insights include recommendations and links to view and explore data and take quick action.

Threat Trackers

Threat Trackers are informative widgets and views that provide authorized users with intelligence on cybersecurity issues that might impact your organization.


Explorer (also referred to as Threat Explorer) is a real-time report that lets authorized users identify and analyze recent threats. By default, this report shows data for the past 7 days; however, views can be modified to show data for the past 30 days.

Automated incident response

Automated incident response (AIR) capabilities available in Office 365 ATP Plan 2 enable you to run automated investigation processes in response to well-known threats that exist today. By automating certain investigation tasks, your security operations team can operate more efficiently and effectively. Remediation actions, such as deleting malicious email messages, are taken upon approval by your security operations team. To learn more, see How AIR works in Office 365.

Attack Simulator

Attack Simulator lets authorized users run realistic attack scenarios in your organization. Several different kinds of attacks are available, including a display name spear-phishing attack, a password-spray attack, and a brute-force password attack.
