Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.

The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Best value if you already pay for Microsoft 365... Microsoft Purview DLP is a no-brainer—no new infrastructure, just policy configuration.” GLM 4.7 FlashX · DLP · budget prompt · first choice

“If you use Microsoft 365: Start with Microsoft Purview DLP for Exchange, SharePoint, and OneDrive if your licenses include it.” GPT-6 Luna · DLP · budget prompt · first choice

“The top 5 Data Loss Prevention solutions are Microsoft Purview Data Loss Prevention... best for teams standardized on Microsoft 365” Claude Haiku 4.5 · DLP · comparative prompt · first choice

“Try free trials of Safetica or Microsoft Purview (if applicable)—they balance cost, ease, and effectiveness for limited budgets.” Grok 4.20 · DLP · budget prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“When to avoid: Non-Microsoft ecosystems or diverse file types/GenAI risks.” Grok 4.20 · DLP · negative prompt · hard negative

“Microsoft Purview is highly effective if your organization is completely standardized on the Windows and Microsoft 365 ecosystem. However, you should be cautious if your environment is heterogeneous.” Gemini 3.5 Flash · DLP · negative prompt · soft negative

“Common caution themes in recent reviews include missing basic capabilities for some use cases, inconsistent design across workloads, and support that reviewers describe as slow or inflexible.” GPT-5.4 mini · DLP · negative prompt · soft negative

“Purview offers AI-related visibility and compliance features, but some capabilities require specific licenses or pay-as-you-go billing, so it isn't automatically free with Microsoft 365.” GPT-6 Luna · AI governance · budget prompt · soft negative
