Technical, Security & Integration Overview
Technical, Security & Integration Overview
Pryvate Integrator SDK provides a method for embedding secure messaging, voice, and video communication directly into third-party applications.
It is designed for platforms operating in environments where communication represents a material risk surface — including financial systems, healthcare platforms, legal workflows, and government applications.
Pryvate does not function as an external messaging service. It operates as a communications subsystem, embedded within the integrator's architecture and governed by the integrator's backend systems.
A full technical dossier is available for architecture and security review.

Why Communication is a Risk Surface
For platform operators, communication introduces structural risk:
Sensitive data transmitted through external messaging tools
Loss of control over user interaction channels
Inability to govern communication lifecycle
Increased exposure to regulatory and operational risk
Sensitive data transmitted through external messaging tools
Loss of control over user interaction channels
Inability to govern communication lifecycle
Increased exposure to regulatory and operational risk
Many platforms attempt to solve this by building internally or relying on external tools. Both introduce complexity, cost, or loss of control. Pryvate Integrator introduces a controlled, embedded communication layer.
Two Coordinated Layers
Backend Integration Layer
Your system integrates with Pryvate via secure APIs:
- •user registration
- •token generation
- •session control
This layer ensures all communication capability is governed by your backend.
SDK Runtime Layer (Client Application)
The SDK is embedded within your mobile application and provides:
- •messaging interfaces
- •voice and video capability
- •communication state management
- •push notification handling
The SDK operates within your application context and does not replace your product.
Backend-Controlled Lifecycle
User Registration
Users originate from your platform and are registered into the communication layer.
- •Unique identifiers are provided by your system
- •Registration is performed via secure API calls
- •HMAC-based authentication ensures request integrity
Credential Issuance
Your backend generates communication credentials:
- •access tokens
- •session configuration
- •device identifiers
These credentials are required for SDK initialisation and are not exposed outside controlled environments.
SDK Initialisation
The SDK is initialised within your application:
- •communication runtime is bootstrapped
- •session credentials are applied
- •communication services are activated
Communication Execution
Users interact through your application:
- •messaging, voice, and video are delivered in-app
- •communication is governed by your workflows
- •no external messaging dependency exists
Your Platform Retains Full Control
Pryvate does NOT assume control over:
- user identity
- application workflows
- customer relationships
Instead, it enables:
- backend-controlled communication access
- structured session lifecycle
- role-based participation models
- integration with platform governance policies
This ensures communication remains a controlled subsystem, not an uncontrolled extension.
Zero-Trust Communication Architecture
Encryption Model
- •End-to-end encryption applied at device level
- •Communication servers do not access plaintext
- •Session-based encryption keys
- •Forward secrecy for communication sessions
Trust Model
- •Network infrastructure is not trusted
- •Transport layers are not trusted
- •Only endpoint devices can decrypt content
- •Aligns with zero-trust communication principles
Key Characteristics
- •Device-centric key generation
- •No server-side private key storage
- •Ephemeral session keys
- •Application-layer encryption for media
Threat Mitigation
- •Network interception
- •Infrastructure-level access
- •Metadata profiling
- •Uncontrolled communication surfaces

Flexible Integration Models for Secure Communication
Pryvate Integrator provides multiple approaches for embedding secure messaging, voice, and video into your platform.
Each integration method is designed to align with your system architecture, user experience requirements, and governance model — without introducing external dependencies or loss of control.
Most integrations begin with the SDK, with additional models introduced as platform requirements evolve.
Embedded SDK Integration (Mobile)
Integrate secure communication directly into your mobile application using Pryvate's SDK.
- •Real-time messaging, voice, and video
- •Fully embedded within your user experience
- •Backend-controlled access and session lifecycle
Web SDK Integration
Extend secure communication into browser-based platforms and client portals.
- •Consistent communication layer across web environments
- •Designed for SaaS platforms and enterprise systems
- •Aligned with the same security and governance model
Backend Integration
Enable communication through backend-driven workflows without requiring client SDK integration.
- •System-triggered communication events
- •Suitable for automation and workflow-based systems
- •No dependency on user-facing communication interfaces
Custom Deployment Models
Support for platforms with specific infrastructure, security, or regulatory requirements.
- •Private or isolated deployment environments
- •Alignment with high-security and regulated use cases
- •Flexible integration tailored to system constraints
Designed for Controlled Communication
All integration methods are built on the same core principles:
Communication remains fully contained within your platform
Access and participation are governed by your backend systems
Encryption is applied end-to-end at the communication layer
No reliance on external messaging applications

Discuss Your Integration ArchitectureTechnical & Security Dossier
For organisations requiring a deeper understanding of architecture, security model, and governance alignment, a full technical dossier is available.
This document provides a detailed breakdown of:
- •Security architecture and encryption model
- •Control and governance framework
- •Risk exposure and mitigation approach
- •Integration model and system design
The dossier is intended for technical stakeholders, including architects, security teams, and procurement functions evaluating integration into regulated or high-trust environments.
What Pryvate Integrator Is
It is: a communication infrastructure layer for platforms.
When to Use This Model
This approach is suitable when:
- communication must be embedded within your platform
- external messaging tools are not acceptable
- user identity and access must remain under your control
- communication introduces regulatory or operational risk
