A DLP profile is a collection of regular expressions anddetection entries that define the data patterns you want to detect. Cloudflare DLP provides predefined profiles for common detections, or you can build custom DLP profiles specific to your data, organization, and risk tolerance.

1. InCloudflare One ↗, go toData loss prevention >Profiles.
2. Choose apredefined profile and selectEdit.
3. Enable one or moreDetection entries according to your preferences. The DLP Profile matches using the OR logical operator — if multiple entries are enabled, your data needs to match only one of the entries.
4. SelectSave profile.

You can now use this profile in aDLP policy orCASB integration.

1. InCloudflare One ↗, go toData loss prevention >Profiles.

2. SelectCreate profile.

3. Enter a name and optional description for the profile.

4. Add custom or existing detection entries.

   Add a custom entry

   1. SelectAdd custom entry and give it a name.

   2. InValue, enter a regular expression (or regex) that defines the text pattern you want to detect. For example,test\d\d will detect the wordtest followed by two digits.

      • Regular expressions are written in Rust. We recommend validating your regex withRustexp ↗.
      • DLP detects UTF-8 characters, which can be up to 4 bytes each. Custom text pattern detections are limited to 1024 bytes in length.
      • DLP does not support regular expressions with+ or* operators because they are prone to exceeding the length limit. For example, the regex patterna+ can detect an infinite number ofa characters. We recommend usinga{min,max} instead, such asa{1,1024}.

   3. To save the detection entry, selectDone.

   Add existing entries

   Existing entries includepredefined anduser-defined detection entries.

   1. SelectAdd existing entries.
   2. Choose which entries you want to add, then selectConfirm.
   3. To save the detection entry, selectDone.

5. (Optional) Configureprofile settings for the profile.

6. SelectSave profile.

You can now use this profile in aDLP policy orCASB integration.
