Microsoft Exchange Online 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 admins insight into the kind of attacks happening in your organization.

The following are the primary ways you can use ATP for messaging protection:

  • In an Exchange Online Protection filtering-only scenario ATP provides cloud-based email protection for your on-premises Exchange Server 2013 environment, legacy Exchange Server versions, or any other on-premises SMTP email solution.

  • As a part of Microsoft Exchange Online ATP can be enabled to protect Exchange Online cloud-hosted mailboxes. To learn more about Exchange Online, see the Exchange Online Service Description.

  • 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.

ATP’s Safe Links feature proactively protects your users from malicious hyperlinks in a message. The protection remains every time they click the link, as malicious links are dynamically blocked while good links can be accessed.

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.
