## Detect source code leaks with Data Loss Prevention

Jan 20, 2025 

[ Data Loss Prevention ](https://edgetunnel-b2h.pages.dev/cloudflare-one/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://edgetunnel-b2h.pages.dev/cloudflare-one/data-loss-prevention/dlp-profiles/predefined-profiles/#source-code).

For more details, refer to [DLP profiles](https://edgetunnel-b2h.pages.dev/cloudflare-one/data-loss-prevention/dlp-profiles/).
