Purview can do a lot.
Usually it does little.
Microsoft Purview can classify data, prevent exfiltration and report incidents. That it does little of this usually has the same causes: labels not defined, policies in audit-only mode, business units not involved. We build DLP from classification through to enforced policy — with an operating model that reduces false positives.
What is included.
Set up Purview so that it protects without getting in the way.
Classification scheme
Sensitivity labels derived from your protection classes; auto-labelling for detectable data types.
Policy design
DLP rules per channel — Exchange, SharePoint, Teams, endpoint — with exceptions and escalation tiers.
Staged rollout
Audit → notify → block, business unit by business unit, measuring the false-positive rate.
Operating model
Who triages alerts, who approves exceptions, how rules are maintained; reports to data protection and management.
Five steps,
one deliverable.
Protection classes
Which data sits where, and what losing it would cost.
Labels
Define the scheme, pilot it, test auto-labelling.
Policies
Build rules, measure in audit mode, sharpen.
Enforcement
Block channel by channel; involve the business units.
Operations
Hand over alert triage, exception process and quarterly reporting.
