75/100
Microsoft Defender for Office 365 seamlessly protects email, Teams, and SharePoint for organizations already using Microsoft 365. It offers centralized management through the Microsoft 365 Defender portal but requires ecosystem commitment. Security teams benefit from unified identity and threat intelligence across the Microsoft stack.
65/100
Agari excels at email authentication and gateway-based perimeter defense, making it ideal for organizations prioritizing SPF/DKIM/DMARC compliance and brand protection. However, it requires MX record changes and lacks Abnormal’s behavioral biometrics and invisible API-first architecture. It fits teams seeking traditional Secure Email Gateways over modern API-native detection.

You already standardize on this app.
Choose if you are already invested in Microsoft 365 and want unified security management.
Your organization requires DMARC authentication, brand protection, and traditional Secure Email Gateway capabilities.
Public pricing or fit signals no longer match your needs.
Avoid if you require API-first email security for mixed cloud environments or Google Workspace.
You need API-first deployment without infrastructure changes or AI-native behavioral analysis of internal communications.
