Microsoft enhances online protection for Office 365 users

Microsoft has introduced a new e-mail filtering service for Office 365 that provides greater protection against specific types of advanced online threats.

While Office 365 already provides robust e-mail protection against spam, viruses and malware with Exchange Online Protection (EOP), this new service – Exchange Online Advanced Threat Protection (ATP) – works to protect users from increasingly sophisticated attacks.

With a feature called Safe Attachments, ATP protects against unknown malware and viruses. It works by routing all messages and attachments that don’t have a known virus/malware signature to a special hypervisor environment, where a behaviour analysis is performed using 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.

Other features include Safe Links, which protects against malicious URLs that have seemingly safe links, and rich reporting and tracking capabilities, so that IT can gain critical insights into who is being targeted in the organisation and the category of attacks they are facing.

ATP is currently in private preview and is expected to be available this summer as an optional service for Office 365 commercial customers.
