Securing data runs in a sequence. Watch one file move through its life and pick up a layer of protection at each stage. The tools follow the same path.

Know your data
You can't protect what you can't see. Find the sensitive data you actually hold, and learn exactly how Purview classifies it.
Data Classifier Explorer
Browse the 380+ Sensitive Information Types and trainable classifiers built into Purview. Filter by country, regulation, or information type.
SIT X-Ray
See inside the built-in SITs: every pattern, confidence value, keyword list, and checksum, the way Purview defines them. Paste the text from a DLP false positive and find out exactly why it matched.
Custom SIT Builder
Design custom sensitive information types and test them live: patterns, supporting elements, proximity windows, checksums, and the highest-confidence-wins result, with design warnings as you build.
SIT Recipe Library
Proven custom SIT recipes for things the built-in SITs miss: credential spreadsheets, connection strings, internal API tokens, and more. Each one opens in the Builder with sample text loaded.
Trainable Classifier Lab
How trainable classifiers work, a decision guide across SITs, EDM, fingerprinting, and classifiers, plus an exportable project checklist for building a custom one.
The layers around it
The lifecycle sits inside a wider programme: watching for risk, governing AI, and keeping access least-privilege.
