1. What is WebRTC?

WebRTC (Web Real-Time Communication) is an open-source project that enables browsers and mobile applications to provide real-time communication (RTC) via simple APIs. It allows for video calling, voice, and data sharing without needing external plugins.

2. Why Security in WebRTC Matters

Since WebRTC enables direct peer-to-peer communication over the internet, it’s crucial to ensure security at all levels:

Data confidentiality
Protection from eavesdropping
Resistance against spoofing and denial-of-service (DoS) attacks
Secure signaling mechanisms

When poorly implemented, WebRTC can expose IP addresses, allow unauthorized access, and compromise business-critical communication.

3. Common Security Challenges in WebRTC

Signaling Layer Vulnerabilities
Although WebRTC uses secure communication (DTLS/SRTP), the signaling layer is left to the application. Insecure signaling can expose vulnerabilities.
IP Leakage
Without configuration, WebRTC may reveal users' private IP addresses via STUN servers.
Unencrypted Media
Media transmission must be encrypted end-to-end. Improper configurations or proxies can expose data.
Malicious JavaScript
Attackers can exploit JavaScript-based apps to gain unauthorized access to media streams.
Lack of Identity Verification
Weak authentication mechanisms can lead to impersonation attacks and fraud.

4. Key Technologies That Secure WebRTC Communication

At Sheerbit, we implement multiple security layers:

DTLS (Datagram Transport Layer Security): Secures signaling paths and handshake.
SRTP (Secure Real-Time Protocol): Encrypts and authenticates RTP streams.
TURN and STUN Servers: Securely manage NAT traversal.
ICE (Interactive Connectivity Establishment): Optimizes and secures media routing.
JWT & OAuth: Manage user authentication and authorization.

5. Sheerbit’s Secure WebRTC Architecture Explained

Our architecture follows the principle of zero-trust, secure-by-design communication:

Signaling Server Security: We use encrypted WebSockets over TLS and strict authentication.
Firewall Rules and NAT Traversal: Ensuring only whitelisted media traffic can flow.
TURN Server Encryption: All relayed media goes through encrypted TURN channels.
Web Application Firewall (WAF): Blocks malicious attacks on frontend WebRTC apps.
Access Logs and Monitoring: We actively monitor traffic for anomalies.

6. Encryption Protocols We Implement

We use industry-best encryption across every WebRTC layer:

TLS 1.3 for signaling and HTTPS APIs
DTLS 1.2 for media negotiation
AES-128/256 for SRTP encryption
Secure Identity Frameworks to verify user identity before call initiation
Zero-Knowledge Proofs for privacy-first communication (in select apps)

All encryption keys are rotated frequently and stored securely using cloud-native secrets managers.

7. Preventing Unauthorized Access and Attacks

Our secure implementation protects against:

Replay Attacks
Man-in-the-Middle Attacks
Cross-Site Scripting (XSS)
Denial-of-Service (DoS)
IP Spoofing

We implement rate limiting, two-factor authentication (2FA), CAPTCHA mechanisms, and server-level geo-blocking to minimize threat exposure.

8. WebRTC Security for Telehealth, Finance, and Enterprises

Different industries have different compliance needs. Sheerbit offers domain-specific secure WebRTC solutions:

Telehealth: HIPAA-compliant audio/video sessions with secure media archiving.
Banking & Finance: Encrypted face-verification calls with biometric security.
Corporate Conferencing: SSO integration, private TURN servers, and secure chat.

9. Real-world Example: Securing a WebRTC-based Telemedicine Platform

Client: A US-based telemedicine startup
Challenge: The platform needed secure video consultations, encrypted medical file sharing, and HIPAA compliance.

Solution by Sheerbit:

Setup of a HIPAA-ready media server
Integration with encrypted TURN and custom STUN servers
Enforced secure WebSocket signaling
Multi-user roles with access control
Patient identity verification via government ID + facial recognition

Outcome: 250% increase in usage in 3 months with zero reported data breaches.

10. Why Choose Sheerbit for Secure WebRTC Development

11. Final Thoughts

WebRTC is powerful—but only when implemented securely. Many platforms fall short by ignoring signaling encryption, access control, or server-side validation. Sheerbit fills this gap by designing secure-by-default WebRTC apps that scale with your business.

Whether you're building a video chat app, a remote diagnosis tool, or a secure collaboration suite, security cannot be an afterthought and Sheerbit is your partner in building it right.
