Cloudflare has announced the launch of a new Data Loss Prevention (DLP) feature called Exact Data Match (EDM). This feature allows customers to securely provide specific sensitive data, such as credit card numbers or personal information, which Cloudflare will then use to identify, log, and block the presence or movement of that data within the customer's traffic or repositories. By using a finite list of hashed data provided by the customer, EDM reduces false positives compared to generic pattern matching while maintaining privacy. This feature is now available for all DLP customers.
