AI Guardrails & Forensic Logging

Ironclad security controls for enterprise AI operations — PII protection, immutable auditing, zero-trust access

Our multi-layered PII protection system ensures sensitive personal data never reaches AI models. Detection, masking, and tokenization happen in real-time at the AI boundary.

  • 30+ PII types detected including Thai national ID, passport, phone
  • Real-time masking adds less than 5ms latency
  • Reversible tokenization for authorized de-masking
  • Thai-specific PII patterns trained on real regulatory data

PII Masking at the AI Boundary

Before any data reaches an AI model, our PII Masking layer automatically detects and redacts personal identifiable information — Thai national IDs, passport numbers, phone numbers, addresses. The AI processes sanitized data; original PII is never exposed to the model layer.

Our PII detection engine uses a combination of pattern matching, named entity recognition, and contextual analysis specifically trained for Thai PII formats. It recognizes Thai national ID structures, Thai phone number formats, and Thai address patterns that generic solutions miss.

  • Detects 30+ PII types including Thai-specific formats
  • Real-time masking with <5ms overhead per request
  • Reversible tokenization — authorized users can de-mask when needed
  • Custom PII patterns configurable per department or use case

Forensic-Grade Immutable Logs

Every AI interaction is recorded in cryptographically sealed, immutable audit logs. PDPA Audit Trails capture who queried what, when, what data was accessed, and what the AI returned. These logs are admissible for regulatory audits and cannot be altered or deleted.

  • Cryptographic hash chains prevent log tampering
  • Full query-response capture with timestamp and user identity
  • PDPA Section 37 compliance for data processing records
  • Export-ready formats for regulatory audit submissions

Role-Based Access Control (RBAC)

Granular RBAC ensures each user only accesses AI capabilities appropriate to their role and clearance level. Combined with attribute-based policies, the system enforces need-to-know principles automatically. Zero Trust architecture means every request is authenticated and authorized in real-time.

  • Hierarchical role definitions with inheritance
  • Attribute-based access policies (time, location, device)
  • Integration with Active Directory, LDAP, and SSO providers
  • Real-time authorization — no cached permissions
  • Multi-tenancy with department-level data isolation
  • AES-256 encryption at rest, TLS 1.2+ in transit

Enterprise Integration & Multi-Tenancy

Support multiple departments and organizational units with complete data isolation. Each tenant operates within its own secure boundary while sharing the same infrastructure. Integration with enterprise identity providers ensures seamless access management across your organization.

  • Department-level data isolation with strict boundary enforcement
  • Active Directory, LDAP, SAML 2.0, and OpenID Connect integration
  • Single sign-on (SSO) support for enterprise-wide deployment
  • REST API for integration with existing enterprise applications
  • Centralized administration with delegated department management

How It Works

1

Intercept Request

Every AI query passes through the guardrail gateway, which authenticates the user and validates their access level.

2

Detect & Mask PII

The PII engine scans the query for sensitive data and applies real-time masking before the request reaches any AI model.

3

Process Safely

The AI model receives only sanitized data, generates a response, and the guardrail layer logs the complete interaction.

4

Audit & Deliver

The response is logged immutably, PII tokens are restored for authorized users, and the answer is delivered securely.

Use Cases
