Microsoft Defender for Office 365
Microsoft Defender for Office 365 (formerly known as Office 365 Advanced Threat Protection - ATP) is a service from Microsoft that protects users from malicious threats posed by email messages, URL links and collaboration tools.
The protections cover 3 areas:
- Safe Links – It protects you against malicious URL embedded in your received emails by scanning and re-writing the URL. This helps you against phishing attack
- Safe Attachments – it protects you against zero-day malware which cannot be detected by traditional anti-virus tools
- Protection for SharePoint/ Teams/ OneDrive – extends the above protection to your cloud storage
