Office 365 Advanced Threat Protection Service Description
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. ATP has rich reporting and URL trace capabilities that give administrators insight into the kind of attacks happening in your organization.
The following are the primary ways you can use ATP for message protection:
In an Office 365 ATP filtering-only scenario, ATP provides cloud-based email protection for your on-premises Exchange Server environment or any other on-premises SMTP email solution.

In a hybrid deployment, ATP can be configured to protect your messaging environment and control mail routing when you have a mix of on-premises and cloud mailboxes with Exchange Online Protection for inbound email filtering.

Advanced Threat Protection (ATP) Capabilities
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.
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 click the link, as malicious links are dynamically blocked while good links can be accessed.
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.
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.
Monitoring capabilities available in the Office 365 Security & Compliance Center include real-time reports and insights that enable your security and compliance administrators to 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 also take quick actions.
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 enables authorized users to 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.
Attack Simulator enables authorized users to 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.
