Microsoft Defender for Office 365 (Plan 1)

With Safe Attachments, you can prevent malicious attachments from impacting your messaging environment, even if their signatures are not known. All suspicious content goes through a real-time behavioral malware analysis that uses machine learning techniques to evaluate the content for suspicious activity. Unsafe attachments are sandboxed in a detonation chamber before being sent to recipients. The advantage is a malware-free and cleaner inbox with better zero-day attack protection.

Gain critical insights into who is being targeted in your organization and the category of attacks you are facing. Reporting and message trace allow you to investigate messages that have been blocked due to unknown viruses or malware, while URL trace capability allows you to track individual malicious links in the messages that have been clicked.
