Category: WebRTC

WebRTC is exceptionally good at discovering how devices can reach each other across complex networks — and that strength is also its quiet weakness. In the process of making real-time communication work everywhere, WebRTC can expose IP addresses, routing details, and infrastructure topology that were never meant to be public.

WebRTC is often described as “secure by default,” thanks to strong browser enforcement, encrypted signaling, and protected media streams. Yet in real-world deployments, breaches almost never start with broken cryptography.

WebRTC is often treated as a black box. In this deep dive, we open it up — examining how signaling, NAT traversal, media pipelines, and security layers work together to deliver real-time communication in the browser. Expect code, protocol details, and hard-won lessons from building real WebRTC systems.
