# Why blocking WebRTC does not prevent detection

Almost all anti-detect browsers on the market simply block <mark style="color:purple;">WebRTC</mark>, so there is no leak. But that is also a red flag. For most ordinary users <mark style="color:purple;">WebRTC</mark> works, and if it is disabled, that also raises suspicion.

**The only correct way is not to block&#x20;**<mark style="color:purple;">**WebRTC**</mark>**, but to proxy it properly through a UDP proxy, and for that both the browser (or software) and the proxies themselves must support it.**
