Data loss prevention (DLP) custom pattern entries can use Cloudflare Workers in your account to validate matches with organization-specific logic. Your Worker can adjust a match's confidence or reject the match.

For setup steps and the Worker contract, refer to [Validate data loss prevention matches with Cloudflare Workers](https://developers.cloudflare.com/cloudflare-one/data-loss-prevention/detection-entries/custom-validation-workers/).
