## Case Sensitive Custom Word Lists

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

Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/changelog/post/2025-05-12-case-sensitive-cwl/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)

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