M365 DEF-SA-E3 Mappings

Safe Attachments provides an additional layer of protection against malware and protects your organization from inadvertently sharing malicious files. After files are asynchronously scanned by the common virus detection engine in Microsoft 365, Safe Attachments opens files in a virtual environment to see what happens (a process known as detonation).
