## What the models said for it

- "Start with Microsoft Purview Suite ($10-12/user/month) if you're already in the Microsoft ecosystem—it offers the best balance of features, support, and predictable costs." (Kimi K2, DSPM)
- "I'd start with Microsoft Purview's AI security and data-governance controls, alongside Defender for Cloud Apps—not buy a separate “AI security platform” first." (GPT-6 Luna, AI security)
- "Barracuda Cloud Archiving (for email) or Microsoft Purview (if you're already on M365) are the safest, most cost-effective choices" (DeepSeek V4 Flash, Comms archiving)
- "Coro and Microsoft Purview are highly recommended for small businesses and startups (under 500 employees)" (Mistral Small, Insider risk)

## And against it

- "user feedback and reviews frequently highlight immense friction, spotty lineage, and high database scanning costs when trying to integrate Purview with non-Microsoft environments" (Gemini 3.5 Flash, Data catalogs)
- "Microsoft Purview's visibility is strongest within the Microsoft ecosystem; organizations using significant non-Microsoft infrastructure will have gaps" (Claude Haiku 4.5, Insider risk)
- "is outstanding for Microsoft-heavy environments ... but is notoriously limited when dealing with AWS, GCP, or non-Microsoft SaaS applications" (Gemini 3.5 Flash, DSPM)
- "organizations that don't already have M365 E5 licensing will find that advanced DSPM capabilities come at significant additional cost" (Claude Haiku 4.5, DSPM)
