Know your data

To understand your data landscape and identify sensitive data across your hybrid environment, use the following capabilities:

Capability What problems does it solve? Get started
Sensitive information types Identifies sensitive data by using built-in or custom regular expressions or a function. Corroborative evidence includes keywords, confidence levels, and proximity. Customize a built-in sensitive information type
Trainable classifiers Identifies sensitive data by using examples of the data you're interested in rather than identifying elements in the item (pattern matching). You can use built-in classifiers or train a classifier with your own content. Get started with trainable classifiers
Data classification A graphical identification of items in your organization that have a sensitivity label, a retention label, or have been classified. You can also use this information to gain insights into the actions that your users are taking on these items. Get started with content explorer

Get started with activity explorer

Protect your data

To apply flexible protection actions that include encryption, access restrictions, and visual markings, use the following capabilities:
