## What the models said for it

- "If your workforce relies primarily on Microsoft 365 and Windows endpoints, Microsoft Purview provides the lowest barrier to entry and fastest time to value." (Gemini 3.5 Flash, DLP)
- "For most mid-market B2B companies, Microsoft Purview DLP offers the best combination of price, functionality, and ease of use" (MiniMax M2.5, DLP)
- "Microsoft Purview is consistently ranked #1 for bundled estate DLP because it's woven into the Microsoft 365 compliance stack." (Kimi K2, DLP)

## And against it

- "Purview and Google Vault can be appropriate inside a single ecosystem, but they may not cover cross-platform capture, advanced supervision, or all long-term regulatory requirements" (Perplexity Sonar, Comms archiving)
- "Initial versions had high false positive rates - Complex policy creation for some users - Limited customization options in early iterations" (MiniMax M2.5, DLP)
- "protection weakens outside Microsoft services and custom classifiers may require training data and substantial tuning" (Perplexity Sonar, DLP)
- "Microsoft Purview's endpoint controls have browser-specific requirements and supported-action differences" (GPT-6 Luna, DLP)
