## What the models said for it

- "I'd suggest starting with Microsoft Defender for Office 365 if you're on M365, or Proofpoint Core Email Protection if you need more advanced features" (MiniMax M2.5, Email security)
- "look toward platforms that specialize exclusively in email security ... such as Microsoft Defender for Office 365, Proofpoint, Mimecast, or Netskope." (Qwen 3.7 Flash, Email security)

## And against it

- "Proofpoint is priced and configured for enterprise environments with significant operational complexity... it just may not be suitable for smaller organizations." (Claude Haiku 4.5, Email security)
- "Traditional SEGs (like legacy Proofpoint or Mimecast setups) require rerouting your MX records, which is complex to manage and can disrupt mail flow." (Gemini 3.5 Flash, Email security)
- "priced and configured for enterprise environments with significant operational complexity and generally positioned above SMB budgets" (Claude Haiku 4.5, Email security)
- "More enterprise-oriented; may be overkill and over-budget for typical mid-market needs." (Kimi K2, Email security)
