Purview is where your tenant learns what data it has, what it is allowed to do with it, and how to prove it later. This dojo starts with visibility: audit, roles, labels and discovery. Then it moves into DLP, retention, eDiscovery, insider risk, communication compliance and the AI-era posture work that stops Copilot finding your old permission mistakes at machine speed.
Read this first - evidence before enforcement
Purview controls are powerful because they touch evidence, sensitive data, retention, investigations and user behaviour. The safe order is visibility first, then warnings and simulation, then enforcement once the business has seen the impact.
- Start with audit and roles. Know what is logged and who can search it.
- Keep labels simple. If people cannot explain a label, they will not apply it correctly.
- Run DLP in simulation first. False positives are design input, not failure.
- Separate duties. Compliance visibility does not require daily Global Administrator use.
- Collect evidence monthly. An audit should find a trail, not start a treasure hunt.

Size up your environment
Three questions. The base licence still matters, but Purview has enough add-ons and workload-specific gates that this dojo asks directly rather than guessing.
Which licences do you have in the tenant? Select all that apply.
Which Purview capability set do you have?
Not sure keeps premium controls visible with licence chips, so you can investigate rather than lose the thread.
Is Microsoft 365 Copilot licensed or planned?
Walk out with a plan
Your deployment plan lists every in-scope control with status, MITRE references and Microsoft Learn source. The PowerShell working document keeps safe reads active, comments out writes, and turns portal-only work into checklist sections.
