## What the models said for it

- "Best for: Deep integration into Outlook, Teams, Word, Excel, and SharePoint... Why it wins for Mid-Market: Inherits your existing Microsoft Entra ID permissions out of the box" (Gemini 3.5 Flash, Enterprise AI)
- "For a typical mid-market B2B company already on Microsoft 365, Microsoft 365 Copilot is the most practical, cost-effective starting point." (DeepSeek V4 Flash, Enterprise AI)
- "I recommend Microsoft Copilot (especially if you're already on Microsoft 365) or Glean as the top company-wide AI chatbot for employees." (Grok 4.20, Enterprise AI)
- "If your organization is heavily standardized on M365 or Google: Microsoft 365 Copilot or Gemini Enterprise offer the fastest ROI" (Gemini 3.5 Flash, Enterprise AI)

## And against it

- "Avoid Microsoft 365 Copilot in its default configuration (too broad access)" (GLM 4.7 FlashX, Enterprise AI)
- "Enterprise platform integrations such as Microsoft 365 Copilot, Google Gemini for Workspace, or Salesforce Einstein... their deep integration means the AI inherits existing internal user permissions" (Gemini 3.5 Flash, Enterprise AI)
- "Microsoft's own security guidance notes the specific data risk for Copilot: with the right permissions, Microsoft Copilot can access your emails, documents, and Teams messages" (Muse Glimmer 30B, AI security)
- "Enterprise versions like those in Microsoft 365 Copilot (rated C/use with caution) improve this but still access broad tenant data" (Grok 4.20, AI security)
