## What the models said for it

- "the best starting point is Microsoft Entra External ID if you're already in the Microsoft ecosystem" (GLM 4.7 FlashX, CIAM)
- "Arguably the most budget-friendly option if you're Microsoft-centric" (DeepSeek V4 Flash, CIAM)
- "deeply integrated into the Azure/Microsoft ecosystem... The developer experience and documentation lag behind developer-first platforms." (Gemini 3.5 Flash, CIAM)
- "A robust enterprise option, especially if your architecture is already heavily integrated with the Microsoft ecosystem." (Gemini 3.5 Flash, CIAM)

## And against it

- "If you are starting a new project, do not build it on Azure AD B2C." (Gemini 3.5 Flash, CIAM)
- "Free up to 50K MAUs, in-preview federation, but historically more painful to customize (custom policies)." (DeepSeek V4 Flash, CIAM)
- "if cost and cloud-native integration matter more than polished CIAM workflow and enterprise B2B features" (GPT-5.4 mini, CIAM)
