## 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/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.
