Key Benefits

Safe Links ‐ proactively protects your users from malicious hyperlinks in a message. The protection remains intact every time a user clicks 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.

Spoof intelligence ‐ detects when a sender appears to be sending mail on behalf of one or more user accounts within one of your organization’s domains. It enables you to review all senders who are spoofing your domain, and then decides whether to allow or to block the sender from sending the mail. Spoof intelligence is available in the Security & Compliance Center on the Anti‐spam settings page.

Quarantine ‐ messages identified by the Office 365 service as spam, bulk mail, phishing mail, containing malware, or because they matched a mail flow rule can be sent to quarantine. By default, Office 365 sends phishing messages and messages containing malware directly to quarantine. Authorized users can review, delete, or manage email messages sent to quarantine.Advanced anti‐phishing capabilities ‐ uses machine learning models to detect phishing messages.
