WebRTC: real-time business video infrastructure
Short answer
WebRTC (Web Real-Time Communication) is a set of open standards (W3C / IETF) built into browsers to transport audio, video, and data in real time, with DTLS-SRTP encryption. For enterprises, WebRTC is the technical foundation of an integrable video platform: signaling, SFU, STUN/TURN, and a video API form the complete architecture.
What is WebRTC technically?
WebRTC covers four building blocks:
- Capture: camera, microphone, and screen sharing via browser APIs;
- Adaptive encoding: bitrate adjustment based on network conditions (simulcast, SVC);
- Encrypted transport: DTLS for negotiation, SRTP for media streams;
- ICE negotiation: establishing the optimal network path between participants.
Unlike HLS or RTMP, WebRTC targets sub-second latency — essential for real-time communication.
Why WebRTC for enterprise infrastructure?
| Criterion | WebRTC | Delayed protocols (HLS, RTMP) |
|---|---|---|
| Latency | Sub-second | 5–30 seconds |
| Browser integration | Native | Player or app required |
| Interactivity | Bidirectional | One-way |
| Encryption | DTLS-SRTP by default | Variable |
| Sovereign deployment | Open-source stacks | Often proprietary CDN |
For IT and engineering teams, WebRTC offers an auditable stack deployable with France hosting or on-premise, without dependency on a single closed binary.
How does a professional WebRTC architecture fit together?
- Signaling (HTTPS WebSocket): exchange of SDP metadata;
- ICE / STUN / TURN: NAT traversal and enterprise firewalls;
- SFU: selective forwarding for multi-participant sessions;
- Application layer: API, authentication, recording, moderation.
WebRTC vs WebSocket: what's the difference?
WebSocket transports text/binary messages between client and server. WebRTC transports peer-to-peer or SFU-routed media streams, with ICE negotiation and built-in video codecs. In practice, WebSocket often serves as the signaling channel; WebRTC carries the video itself.
Integration into existing systems
WebRTC integrates via:
- Video API: room creation, tokens, webhooks;
- Embedded video: iframe or SDK in an existing portal;
- Video integration: CRM, SSO, LDAP directory connections.
Business use cases (customer support, appointments, meetings, live streaming) are delivered by dedicated group products:

Open source stack and sovereignty
Open-source components (mediasoup, Jitsi, Janus, Pion…) enable building a sovereign business video platform hosted in France, with a controlled subcontractor chain — aligned with GDPR requirements.
Key considerations for IT teams
- Firewall: plan documented TURN servers (UDP and TCP);
- SFU sizing: a 1:1 session ≠ a 50-participant meeting;
- Codecs: VP8, VP9, H.264, AV1 depending on browsers and IT policy;
- Monitoring: ICE metrics, bitrate, packet loss for ops runbooks.
How does Leagora use WebRTC?
Leagora designs real-time video infrastructure on a WebRTC foundation: scalable SFU, documented TURN, video API, France or on-premise deployment. leagora.io documents the stack; business products live on the dedicated domains above.

FAQ
Is WebRTC a standard or a product?
It is an open standard (W3C / IETF), not a vendor. Each implementation (Google, Mozilla, open-source stacks) integrates it into its infrastructure.
Does WebRTC work behind a corporate firewall?
Yes, with properly configured and documented TURN servers. Without TURN, strict peer-to-peer connections frequently fail on corporate networks.
What latency should you expect with WebRTC?
Under normal conditions: 200 ms to 1 second for interaction.
Does WebRTC replace Zoom or Teams?
It replaces the transport layer in infrastructure you control (hosting, branding, SI integration).
Can WebRTC be deployed on-premise?
Yes: signaling, SFU, TURN, and storage on your datacenter. See France hosting for Leagora options.
Is WebRTC GDPR-compatible?
The standard alone does not guarantee compliance; governance (hosting, DPA, recordings) determines it.
Key takeaways
- WebRTC = open standards for real-time browser video.
- Pro architecture = signaling + ICE/STUN/TURN + SFU + API layer.
- leagora.io documents infrastructure; business funnels stay on group product sites.
- Sovereignty = open-source stacks + France hosting.
