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/data-loss-prevention/dlp-profiles/predefined-profiles/#source-code).

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