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

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/).

**Detect source code leaks with Data Loss Prevention**

You can now detect source code leaks with Data Loss Prevention (DLP) with predefined checks against common programming languages.

The following programming languages are validated with natural language processing (NLP).

* C
* C++
* C#
* Go
* Haskell
* Java
* JavaScript
* Lua
* Python
* R
* Rust
* Swift

DLP also supports confidence level for [source code profiles](https://developers.cloudflare.com/cloudflare-one/policies/data-loss-prevention/dlp-profiles/predefined-profiles/#source-code).

For more details, refer to [DLP profiles](https://developers.cloudflare.com/cloudflare-one/policies/data-loss-prevention/dlp-profiles/).

**Payload log match visibility**

When viewing decrypted payload log matches, DLP now provides more context by listing multiple DLP matches and the matching DLP profile.

## 2024-11-25

**Profile confidence levels**

DLP profiles now support setting a [confidence level](https://developers.cloudflare.com/cloudflare-one/policies/data-loss-prevention/dlp-profiles/advanced-settings/#confidence-levels) to choose how tolerant its detections are to false positives based on the context of the detection. The higher a profile's confidence level is, the less false positives will be allowed. Confidence levels include Low, Medium, or High. DLP profile confidence levels supersede [context analysis](https://developers.cloudflare.com/cloudflare-one/policies/data-loss-prevention/dlp-profiles/advanced-settings/#context-analysis).

**Send entire HTTP requests to a Logpush destination**

In addition to [logging the payload](https://developers.cloudflare.com/cloudflare-one/policies/data-loss-prevention/dlp-policies/logging-options/#log-the-payload-of-matched-rules) from HTTP requests that matched a DLP policy in Cloudflare Logs, Enterprise users can now configure a [Logpush job](https://developers.cloudflare.com/cloudflare-one/policies/data-loss-prevention/dlp-policies/logging-options/#send-http-requests-to-logpush-destination) to send the entire HTTP request that triggered a DLP match to a storage destination. This allows long-term storage of full requests for use in forensic investigation.

## 2024-09-03

**Exact Data Match multi-entry upload support**

You can now upload files with [multiple columns of data](https://developers.cloudflare.com/cloudflare-one/policies/data-loss-prevention/datasets/#upload-a-new-dataset) as Exact Data Match datasets. DLP can use each column as a separate existing detection entry.

## 2024-05-23

**Data-at-rest DLP for Box and Dropbox**

You can now scan your [Box](https://developers.cloudflare.com/cloudflare-one/applications/casb/casb-integrations/box/#data-loss-prevention-optional) and [Dropbox](https://developers.cloudflare.com/cloudflare-one/applications/casb/casb-integrations/dropbox/#data-loss-prevention-optional) files for DLP matches.

## 2024-04-16

**Optical character recognition**

DLP can now [detect sensitive data](https://developers.cloudflare.com/cloudflare-one/policies/data-loss-prevention/dlp-profiles/advanced-settings/#optical-character-recognition-ocr) in jpeg, jpg, and png files. This helps companies prevent the leak of sensitive data in images, such as screenshots.
