What is Microsoft Defender for Email?

Microsoft Defender for Office 365 provides native protection for Microsoft 365 email. Features include: Safe Attachments (sandboxing), Safe Links (URL protection), anti-phishing policies, and threat investigation tools.

Integration advantage: native to Microsoft 365, no additional deployment required. Unified management with other Microsoft security tools. Continuous updates aligned with Office 365 development.

Considerations: primarily for Microsoft environments, may lack features of dedicated security platforms, and licensing complexity. Many organizations use Defender as foundation with third-party tools for additional protection.
