RapidCall is built on a layered infrastructure designed to protect data across the full call lifecycle, from live call processing through storage and workspace access control.

​
Architecture

The platform is structured across separate application layers rather than as a single monolithic system. At a high level, this includes:
  • a backend API layer,
  • a web dashboard layer,
  • and a real-time voice processing layer.
Those layers are isolated from each other so that the dashboard, API, and voice engine do not all sit in the same runtime surface. This separation reduces the blast radius of a single-component failure or compromise and makes operational access control cleaner. This architecture description reflects the platform design you provided; the underlying cloud and provider security posture is supported by the vendor documentation cited below.

​
Encryption

Data in transit should be encrypted using TLS across browser sessions, API traffic, and internal service communication. For cloud storage and database infrastructure, AWS documents encryption support for services such as S3 and RDS and positions AWS services for GDPR-compliant use when configured appropriately. Payment data is handled by Stripe rather than being stored directly on RapidCall infrastructure. (Amazon Web Services, Inc.)

​
Authentication and workspace isolation

Authentication should be scoped at the workspace level so that access is limited to the environment a user is authorised to manage. Each workspace is designed to operate as a separate environment, with its own agents, phone numbers, call history, recordings, billing context, and team access. This matters especially for agencies and multi-client operators, because it reduces the risk of cross-workspace data exposure and keeps client environments operationally separated.

​
Voice processing

RapidCall uses a real-time streaming architecture for live voice interactions. LiveKit positions its platform as real-time infrastructure for voice and multimodal applications, and its security materials state that LiveKit Cloud maintains SOC 2 Type II certification. Deepgram states that it has achieved SOC 2 Type I and Type II certification for its speech services. This is relevant because real-time call processing depends on low-latency streaming between telephony, speech recognition, model inference, and voice generation providers. (LiveKit)

​
Third-party provider security

RapidCall relies on established infrastructure providers for core parts of the system. Their published security and compliance materials support the baseline security posture of the platform stack. A few important provider-side notes:
  • AWS publishes SOC reports, ISO/IEC 27001 certification information, and GDPR compliance resources. (Amazon Web Services, Inc.)
  • Twilio publishes a security overview, GDPR information, and states that its SOC 2 Type II certification applies across its services. (Twilio)
  • LiveKit states that LiveKit Cloud maintains SOC 2 Type II certification. (LiveKit)
  • Deepgram states that it has SOC 2 Type I and Type II certification. (Deepgram)
Because provider certifications and trust documentation can change over time, it is better to describe the platform as being built on leading cloud, telephony, real-time, transcription, and payment providers, rather than hard-coding every certification claim unless you plan to maintain that section regularly.

​
Account security best practices

A few practical steps materially improve account security: Use strong, unique credentials
Your login protects access to agents, call records, contact data, and billing controls. Treat it accordingly. Use team roles instead of shared logins
Assign access through individual team accounts rather than sharing credentials. This improves accountability and makes it easier to revoke access cleanly. Rotate API keys periodically
If you use the API for custom workflows, rotate keys on a regular schedule and revoke any that are no longer needed. Review workspace access regularly
If you manage multiple workspaces, periodically confirm who still needs access to each one and remove stale access promptly. If you want a tighter, safer version for the public docs, use this: RapidCall is built on a layered infrastructure designed to protect data throughout the call lifecycle. The platform separates the dashboard, backend API, and real-time voice processing layers, helping reduce cross-system exposure and improve operational isolation. Data in transit is protected using encrypted transport, while cloud storage and database infrastructure are built on enterprise-grade providers. Payment data is handled by Stripe and is not stored directly on RapidCall servers. RapidCall also uses workspace-level isolation so each workspace’s agents, call data, phone numbers, billing context, and team access remain separated from other workspaces. The platform relies on established infrastructure providers for cloud hosting, telephony, real-time communications, speech processing, and payments, including AWS, Twilio, LiveKit, Deepgram, and Stripe. These providers publish their own security and compliance documentation, and RapidCall builds on that foundation with platform-level access control and workspace separation.
