# Data Classification

The Data Classification page shows which of your cloud storage resources contain sensitive data, based on the classification profiles and data patterns configured in your settings. It helps you understand where personally identifiable information (PII), financial data, health records, or other sensitive content is stored.

### How Classification Works

DataDefender scans the contents of your storage resources using classification profiles. Each profile contains one or more data patterns (such as a regex for credit card numbers or social security numbers). When a match is found in a resource, that resource appears on this page with the matching profile and pattern shown.

***

### Profile and Pattern Badges

At the top of the page, two rows of badges show all detected classification profiles and data patterns across your environment.

**Classification Profile badges** — Each badge represents a classification profile that has matched at least one file in your environment. Click a profile badge to filter the asset list to only resources matching that profile.

**Data Pattern badges** — Each badge represents an individual data pattern (e.g. "Credit Card Number", "SSN", "IBAN"). Hover over a profile badge to highlight the data patterns it contains. Click a pattern badge to filter by that pattern.

### Asset List

The asset list shows all storage resources that have at least one classification match. Each item displays:

* Resource name and type
* Which classification profiles matched
* Which specific data patterns matched
* AWS region and account

Click any asset to expand it and see the full list of matched profiles and patterns.

### Filtering

#### Filter by Profile or Pattern

Click any badge in the profile or pattern rows to filter the asset list to only resources with that match.

#### Search

Use the search bar to find a specific resource by name. Press `/` on your keyboard to quickly focus the search field.

#### Pagination

Use the **Previous** / **Next** buttons and the page size selector to navigate through the results.

### Triggering a Classification Scan

If you want to re-scan specific resources or scan resources that haven't been classified yet, go to Inventory of Data Stores and use the **Trigger Classification** action from there.
