What the models said for it

Verbatim evidence the judge attached to positive labels.

“I'd recommend starting with Microsoft Purview if you're already invested in Microsoft 365, as it offers the best value integration” MiniMax M2.5 · DLP · paraphrase prompt · first choice
“If you're Microsoft-centric: Microsoft Purview DLP (via E5 or E5 Compliance add-on) is usually the cheapest, most integrated option” GLM 4.7 FlashX · DLP · budget prompt · first choice
“Recommended for mid-market M365-native organizations due to its native integration, low operational burden, and strong coverage” Llama 4 Maverick · DLP · direct prompt · first choice
“If you're Microsoft 365-centric: Start with Microsoft Purview DLP — it integrates natively and reduces tool sprawl.” Kimi K2 · DLP · scale 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.

“Avoid if you have mixed environments or significant non-Microsoft workloads.” Kimi K2 · DLP · negative prompt · hard negative
“Choose Microsoft Purview only if your company is strictly on Windows/M365... Extremely complex to set up, configure, and tune” Gemini 3.5 Flash · DLP · direct prompt · soft negative
“lower-tier Microsoft Purview bundles without E5 licensing) ... basic tiers of built-in DLP are often highly simplistic” Gemini 3.5 Flash · DLP · negative prompt · soft negative
“exposed enforcement failures in Microsoft 365 ecosystems ... risky for strict compliance without monitoring” Grok 4.1 Fast · DLP · negative prompt · soft negative

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Microsoft Purview DLP's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Microsoft Purview DLP, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at microsoft.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
