Security & Trust Architecture
for Regulated Organizations

An end-to-end security and trust framework built on Zero Trust, full-stack Encryption, Audit Trail & Evidence Chain, and AI that never uses customer data for model training.

Designed for projects with central banks, securities regulators, capital markets, banks, insurers, and public sector agencies as a dedicated “confidence-building” page when presenting Vasvox to executives, boards, regulators, and internal audit teams.

Why Security & Trust Architecture Matters for Regulated Industries

For regulated organizations, having “recording features” or “analytics” alone is no longer enough. Regulators and auditors want to see a provable security and trust architecture — how access is controlled, how data is encrypted, how audit trails are recorded, and how AI is used without compromising privacy.

Regulator’s Perspective

They expect solutions to prevent unauthorized access, enforce proper encryption, maintain complete audit trails, and be designed with PDPA / privacy requirements from day one.

Board & Executive Perspective

They need assurance that Recording, Speech Analytics, Contact Center, and AI will not become a weak point leading to data breaches, legal disputes, or reputational damage in the future.

IT & Security Perspective

They require an architecture that integrates well with existing Zero Trust, IAM, SIEM, SOC, and data governance frameworks — without adding unnecessary complexity, while remaining auditable and transparent.

Security Model – Defense-in-Depth & Privacy-by-Design

Vasvox follows a Defense-in-Depth and Privacy-by-Design approach from infrastructure all the way to user experience and API integrations.

Layered Security

  • Network & perimeter security
  • Application & API security controls
  • Data & storage security for recordings and transcripts
  • Identity & access management (IAM)
  • Endpoint & device governance

Least Privilege & Segmentation

  • Role-Based and Attribute-Based Access Control (RBAC / ABAC)
  • Dedicated environments for admin, processing, and evidence storage
  • Just-Enough-Access and Just-in-Time access for sensitive operations
  • Multi-level approvals for high-risk activities

PDPA & Regulatory Alignment

  • Privacy-by-Design across collection, usage, and disclosure
  • Data minimization and purpose limitation principles
  • Configurable retention aligned with sector-specific regulations
  • Architecture ready for internal and external regulatory audits

Zero Trust Architecture – “Never Trust, Always Verify”

The Vasvox Zero Trust design is built on three core principles: Verify Explicitly, Least Privilege Access, and Assume Breach — ensuring that every session, every request, and every evidence access is verified and governed.

Verify Explicitly

  • Identity validated via your Identity Provider / AD / Entra ID
  • Device compliance checks before accessing sensitive evidence
  • Risk-based assessment of user behavior and context
  • Support for Multi-Factor Authentication (MFA)

Least Privilege Access

  • Fine-grained roles: RM, Supervisor, Compliance, Auditor, Admin
  • View / listen / download permissions aligned with policies
  • Just-in-Time access for special investigation cases

Assume Breach

  • Micro-segmentation across services and data zones
  • Comprehensive event logging and forwarding to SIEM / SOC
  • Anomaly detection and alerting for suspicious activities

Encryption Model – Protecting Data In Transit & At Rest

Vasvox implements robust encryption controls for both data in transit and data at rest, aligned with financial-grade security expectations and best practices.

Encryption In Transit

  • TLS 1.2/1.3 for all external connections
  • Encrypted service-to-service communication inside the platform
  • Protection against man-in-the-middle and traffic interception

Encryption At Rest

  • AES-256 for recordings, transcripts, and metadata
  • Automatic key rotation based on organizational policies
  • Logical key isolation per tenant / per organization
  • Optional Bring-Your-Own-Key (BYOK) integration

Secure Evidence Store

  • WORM-like (Write Once Read Many) behavior for evidence
  • Policy-governed deletion and restricted modifications
  • Watermarking and audit metadata attached to every file

For projects requiring strict data residency in Thailand, or integration with existing enterprise encryption frameworks, Vasvox can co-design the architecture with your Security & Infrastructure teams.

Audit Trail & Evidence Chain

Audit Trail & Evidence Chain – Forensic-Grade Digital Evidence

Every access, search, playback, download, and export action is captured in a detailed Audit Trail that can be used as forensic evidence.

What We Capture in the Audit Trail

  • Who accessed which file, when, and via which channel
  • What actions were taken (view, listen, download, share, export)
  • From which IP / device type the access originated
  • Under which policy context and role the access was granted

Evidence Chain for Investigations & Disputes

  • Link recordings, transcripts, chat, screen, metadata, CRM / ticket data into one timeline
  • Support internal investigations, dispute resolution, and legal proceedings
  • Reduce time spent by Compliance and Legal teams collecting and reconciling evidence

This architecture is designed to pass scrutiny from regulators such as central banks, securities regulators, anti-money-laundering offices, and investigation agencies — showing not only features, but true “architectural transparency.”

AI That “Does Not Train on Customer Data” – Designed for Regulated Use

The AI Compliance Policy Engine and related AI modules from Vasvox operate in a strict processing-only mode, where customer content is never used to train or fine-tune the core models.

Processing-Only AI

AI analyzes communications for keywords, potential breaches, suitability, and risk signals — but only processes the data on-the-fly without adding it back into the training dataset of the underlying models.

No Customer Data Training

Customer data from one organization is never turned into “shared knowledge” for others. This avoids cross-tenant leakage risks and maintains clear boundaries for privacy and compliance.

PDPA & Global Regulation Alignment

This approach helps your organization stay aligned with PDPA, GDPR, MiFID II, HIPAA, and internal AI Ethics Guidelines — enabling AI use cases without compromising regulatory posture.

For institutions designing an AI Policy with DPO, Legal, IT, and Business stakeholders, Vasvox can help shape the AI use cases, policies, and controls to fit into your Security & Trust Architecture.

Frequently Asked Questions about Security & Trust Architecture

Key questions that IT, Security, Compliance, and business stakeholders often ask when evaluating Vasvox for regulated, enterprise-scale deployments.

1. Which Vasvox components are covered by this Security & Trust Architecture?

This architecture applies to ASC Recording Insights, ASC Neo, Tendfor Cloud Contact Center, Speech Analytics, and the AI Compliance Policy Engine — including integrations with Microsoft Teams, Dynamics 365, and other CRM / Contact Center systems in your environment.

2. Can Vasvox integrate with our existing Zero Trust, IAM, and SIEM stack?

Yes. Vasvox can leverage your existing Identity Provider and security policies, and forward logs/events to your SIEM / SOC, so that your Security team can continue using the tools and processes they already trust to monitor and investigate incidents.

3. Where are recordings and transcripts stored, and can we ensure data residency in Thailand?

Vasvox supports On-Premise, Hybrid, and Cloud deployment models, and can be architected to meet strict data residency requirements in Thai data centers, with options for Geo-Redundancy and Disaster Recovery depending on your policies.

4. Does the use of AI in the platform create additional PDPA or privacy risks?

Vasvox follows a No Customer Data Training principle. AI features process and analyze data but do not use your customer content to train or fine-tune the underlying models. This significantly reduces PDPA / GDPR risks and addresses common concerns from executives and data protection officers.

5. Can the Audit Trail be used as evidence for internal investigations or legal proceedings?

Yes. The Audit Trail records who did what, to which data, when, and how — in a form suitable for Internal Investigations and, where applicable, submissions to regulators or investigation agencies as supporting evidence.

6. Can Vasvox provide a Security Review or Architecture Workshop with our teams?

Yes. Vasvox can organize a dedicated Security & Trust Architecture Workshop with your IT, Security, Compliance, and business teams to align the solution with your existing standards, frameworks, and regulatory obligations.
