But is it safe?

Webrtc was created encrypted by design, which means that it is not possible to use it unless very high security standards are applied. In particular, our entire platform is served via HTTPS and, being our focal point, we make sure we are always up to date with the latest technologies. That’s why we only use TLS 1.2 security protocol and block encryption suites that are considered unsafe. The same applies to audio/video streams, where the DTLS / SRTP stack is used to protect transport and prevent any type of man attack in the middle.
