Reviewed 2026-10-06 · Update owner: Jason Metzner

SUPERWISE® Sentinel is a focused AI gateway that removes defined data types from routed requests. Microsoft Purview is a broad data-security and compliance system that applies classification, DLP, audit, investigation, retention, and risk controls across Microsoft services, endpoints, and integrated AI applications. The products operate at different scopes.

“Not verified” means the reviewed public vendor sources did not confirm the capability. It does not establish that the capability is absent from a private offer or later release.

When Microsoft Purview is the better fit

Your organization already uses Microsoft 365 and needs DLP, sensitivity labels, audit, retention, eDiscovery, and investigation in the same control plane. [M1] Read 2026-10-06 [M3] Read 2026-10-06
You need discovery and policy across supported third-party AI sites in Edge, Chrome, and Firefox on onboarded devices. [M2] Read 2026-10-06
You need protection across Microsoft 365, Windows or macOS endpoints, and integrated SASE or secure-browser traffic. [M1] Read 2026-10-06 [M4] Read 2026-10-06

When Sentinel fits

You need a direct AI gateway for an application or supported Windows workflow without adopting the wider Purview data-security stack. [S2] Read 2026-10-06 [S3] Read 2026-10-06
You need replacement of emails, phone numbers, account numbers, and API keys before routed requests reach an AI provider. [S4] Read 2026-10-06 [S5] Read 2026-10-06
You want to inspect a public demo before configuring a Microsoft tenant, device onboarding, browser policy, and licensing. [S6] Read 2026-10-06 [M2] Read 2026-10-06
