DLP datasets

Cloudflare DLP can scan your web traffic and SaaS applications for specific data defined in a custom dataset. Sensitive data can be hashed before reaching Cloudflare and redacted from matches in payload logs.

​​ DLP dataset types

​​ Exact Data Match

Exact Data Match (EDM) protects sensitive information, such as names, addresses, phone numbers, and credit card numbers.

All data in uploaded EDM datasets is encrypted before reaching Cloudflare. To detect matches, Cloudflare hashes traffic and compares it to hashes from your dataset. Matched data will be redacted in payload logs.

​​ Custom Wordlist

Custom Wordlist (CWL) protects non-sensitive data, such as intellectual property and SKU numbers.

Cloudflare stores data from CWL datasets within DLP. Plaintext matches appear in payload logs.

​​ Use DLP datasets

​​ Prepare a dataset

To prepare a dataset for DLP, add your desired data to a single-column spreadsheet. Cells must be at least six characters long. Title cells may result in false positives and should not be included. Accepted file formats include .csv and .txt.

For information on dataset limits, refer to Account limits.
