Exact Data Match
Exact Data Match (EDM) allows you to scan your web traffic and SaaS applications for specific data defined in a custom dataset, such as names, addresses, phone numbers, credit card numbers, and more.
All data in uploaded datasets is encrypted before reaching Cloudflare. To detect matches, Cloudflare hashes traffic and compares it to hashes from your dataset.

To prepare a dataset for EDM, add your desired data to a single-column spreadsheet. Spreadsheets can contain a maximum of 100,000 cells.
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.
