## Case Sensitive Custom Word Lists

May 12, 2025

[Data Loss Prevention](https://developers.cloudflare.com/cloudflare-one/data-loss-prevention/)

You can now configure [custom word lists](https://developers.cloudflare.com/cloudflare-one/data-loss-prevention/detection-entries/#custom-wordlist) to enforce case sensitivity. This setting supports flexibility where needed and aims to reduce false positives where letter casing is critical.
