DLP profiles

A DLP profile defines what sensitive data Cloudflare detects in your traffic. A profile combines one or more of the following building blocks:

  • Detection entries — reusable detection logic that identifies sensitive content, such as patterns, datasets, document fingerprints, predefined detections, and AI prompt topics.
  • Data classes — reusable classification rules that combine detection entries and other signals into a single rule.
  • Labels — sensitivity levels and data tags that describe matched content.

Data classes and labels are part of Data Classification. Cloudflare DLP offers three types of profiles:

  • Predefined profiles — Cloudflare-managed profiles for common sensitive data types such as credit card numbers, national identifiers, and AI prompts.
  • Custom profiles — profiles you build from detection entries, data classes, and labels, specific to your data, organization, and risk tolerance.
  • Integration profiles — profiles populated with data classifications from a third-party platform, such as Microsoft Purview sensitivity labels (requires Cloudflare CASB).

Configure a predefined profile

  1. In the Cloudflare dashboard ↗, go to Zero Trust > Data loss prevention > Profiles.
  2. Choose a predefined profile and select Edit.
  3. Enable one or more Detection entries according to your preferences.
  4. Select Save profile.

Most predefined profiles match when any enabled detection entry matches. The Personally Identifiable Information (PII) Record profile is an exception and requires at least three unique detection entries in close proximity before the profile matches.

You can now use this profile in a DLP policy, CASB integration, AI Gateway DLP policy, or Email Security outbound DLP policy.

Build a custom profile

  1. In the Cloudflare dashboard ↗, go to Zero Trust > Data loss prevention > Profiles.

  2. Select Create profile.

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

  4. Add detection entries to the profile.

    Create a custom entry

    1. Select Create custom entry.

    2. Choose the type of detection entry you want to create and configure its values.

      For information on supported detection entry types, refer to Configure detection entries.

    3. To save the detection entry, select Done.

    Add existing entries

    Existing entries include predefined and user-defined detection entries that you manage from the Detection entries section.

    1. Select Add existing entries.
    2. Choose which entries you want to add, then select Confirm.
    3. To finish, select Done.

  5. (Optional) Add data classes to include reusable classification rules.

    • Select Add data classes
    • Choose the data classes you want to add, then select Confirm

  6. (Optional) Use labels as match criteria for the profile.

    • Select a sensitivity schema and minimum sensitivity level.
    • Select a data tag group and one or more data tags.

    For more information on labels, templates, and data classes, refer to Data Classification.

  7. (Optional) Configure profile settings for the profile.

  8. Select Save profile.

You can now use this profile in a DLP policy, CASB integration, AI Gateway DLP policy, or Email Security outbound DLP policy.
