Is Purview enough?
Test the controls your data needs against your actual licenses, workloads and operating capacity before adding another platform.
- Write down the store, action and user population for each required control.
- Compare incremental licenses, consumption charges and operating work for the same scope.
- Add another product only for a demonstrated gap in that scope.
Check the license first
Purview uses complementary per-user and consumption billing. Microsoft 365 and endpoint features depend on licensed plans. Non-Microsoft sources and certain other features use Azure-linked pay-as-you-go billing. An E5 subscription does not establish the cost of every Purview workflow. [2]
Build the quote from required controls, users and locations. Include existing entitlements, incremental licenses, metered usage and the people needed to operate policies.
Separate the workloads
DLP supports Exchange, SharePoint, OneDrive and Teams, alongside endpoint and on-prem scenarios with their own setup requirements. Connected non-Microsoft apps are also documented, with some capabilities in preview. Confirm the status and prerequisites of each required control. [1]
Data Map lists metadata, classification, labeling and policy support separately. For example, its BigQuery entry supports metadata and lineage without automatic classification, while Snowflake supports classification but not data policies. A connector name alone cannot answer whether a product can inspect or block your data. [3]
Test each AI data path
Purview includes browser and network DLP paths for AI applications. Edge for Business has different prerequisites and billing for managed and unmanaged app scenarios. Test the exact app, browser, device and account combination. [1] [4]
- Try typed text, paste, file upload and download with the same sensitive sample.
- Repeat the test on managed and unmanaged devices and with personal and work accounts.
- Record what was blocked, logged or missed and whether an operator can investigate it.
Run a controlled evaluation
Use representative content with known sensitive and harmless examples. Include old files, encrypted documents, unusual formats and legitimate sharing. Agree on acceptable misses, false positives and operator workload before testing.
| Required outcome | Evidence to collect |
|---|---|
| Find sensitive data | Known sensitive samples found, missed items and scan exclusions. |
| Reduce excessive access | Effective permissions, public links, approval steps and rollback. |
| Prevent a transfer | The same content tested through each required channel and device. |
| Operate the control | Investigation time, policy tuning, permissions and ongoing costs. |
Make the decision from gaps
Keep Purview where it meets the agreed tests at an acceptable total cost. Evaluate another platform against the specific failed tests. Require it to demonstrate the missing control with the same data and include its deployment and operating costs.
Use the Purview profile for source-level caveats or compare it with another platform.
