Microsoft yesterday announced the availability of two new capabilities, URL Detonation and Dynamic Delivery for Office 365 Advanced Threat Protection.
URL Detonation helps prevent users from being compromised by files linked to malicious URLs. When a user receives an email, ATP analyzes the URLs for malicious behavior. If a user clicks a malicious link, a pop-window opens notifying the user that the file is malicious and warns the user against opening it.
With Dynamic Delivery, recipients can read and respond to the email while the attachment is being scanned. Dynamic Delivery delivers emails to the recipient’s inbox along with a “placeholder” attachment notifying the user that the real attachment is being scanned. If a user clicks the placeholder attachment, they can check the progress of the scan. If the attachment is malicious, Office 365 Advanced Threat Protection will filter out the attachment.
