## Block files that are password-protected, compressed, or otherwise unscannable.

Feb 03, 2025, 11:00 AM

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

Gateway HTTP policies can now block files that are password-protected, compressed, or otherwise unscannable.

These unscannable files are now matched with the [Download and Upload File Types traffic selectors](https://developers.cloudflare.com/cloudflare-one/policies/gateway/http-policies/#download-and-upload-file-types) for HTTP policies:

* Password-protected Microsoft Office document
* Password-protected PDF
* Password-protected ZIP archive
* Unscannable ZIP archive

To get started inspecting and modifying behavior based on these and other rules, refer to [HTTP filtering](https://developers.cloudflare.com/cloudflare-one/policies/gateway/initial-setup/http/).
