Security Architecture

Zero-trust infrastructure with defense-in-depth principles. Designed for regulated environments requiring high-assurance identity operations.

Encryption Model

Multi-layered encryption architecture protecting data at rest, in transit, and during processing with industry-standard cryptographic primitives.

Transport Security

TLS 1.3 with perfect forward secrecy for all network communications. Certificate pinning prevents man-in-the-middle attacks.

  • • AES-256-GCM cipher suite
  • • ECDHE key exchange
  • • Certificate transparency monitoring

Data at Rest

AES-256 encryption for all stored data including documents, biometric templates, and audit logs with hardware security module (HSM) key management.

  • • FIPS 140-2 Level 3 HSMs
  • • Envelope encryption architecture
  • • Automatic key rotation

Processing Security

Encrypted memory regions during verification and signing operations. Biometric templates never stored in raw form.

  • • Secure enclave utilization
  • • Template hashing with salt
  • • Memory wiping after operations

Cryptographic Standards

Symmetric Encryption
AES-256-GCM, ChaCha20-Poly1305
Asymmetric Encryption
RSA-4096, ECDSA P-384, EdDSA
Hash Functions
SHA-384, SHA-512, BLAKE3
Key Derivation
PBKDF2, Argon2id, HKDF

Key Management

  • • Automated key rotation every 90 days
  • • Multi-party key generation ceremonies
  • • Geographic key distribution
  • • HSM-backed root key storage
  • • Quantum-resistant algorithms roadmap

Tenant Isolation

Dedicated encryption keys, separate database schemas, and network-level isolation for each customer preventing cross-tenant data access.

Geographic Data Residency

Regional data centers with strict data sovereignty controls. Customer data never crosses configured geographic boundaries.

Access Controls

Role-based access control (RBAC) with principle of least privilege. Multi-factor authentication required for all administrative access.

Data Isolation

Multi-tenant architecture with cryptographic separation ensuring customer data remains isolated at storage, processing, and network layers.

Network Segmentation

Virtual private clouds (VPCs) per customer with firewall rules enforcing zero lateral movement between tenant environments.

Database Isolation

Separate database instances or schemas with encryption keys unique to each tenant. Connection pooling prevents cross-contamination.

Compute Isolation

Containerized workloads with namespace isolation and resource quotas. Dedicated processing for sensitive operations.

Zero Trust Architecture

Never trust, always verify. Every request authenticated, authorized, and audited regardless of origin or network location.

Identity Verification

All users and services must authenticate before access is granted. No implicit trust based on network location.

  • • Multi-factor authentication mandatory
  • • Service-to-service mutual TLS
  • • Short-lived access tokens
  • • Continuous authentication validation

Least Privilege

Minimum necessary permissions granted for specific tasks. Access automatically revoked after use.

  • • Granular permission model
  • • Just-in-time access provisioning
  • • Automatic permission expiration
  • • Privilege escalation monitoring

Assume Breach

Architecture designed assuming network compromise. Lateral movement prevented through microsegmentation.

  • • Network microsegmentation
  • • Encrypted east-west traffic
  • • Anomaly detection systems
  • • Automated incident response

Audit Immutability

Tamper-evident audit trail with cryptographic proof of integrity. Every operation logged to immutable ledger for compliance and forensic analysis.

Hash Chaining

Each audit record cryptographically linked to previous record. Tampering detection through hash verification.

Timestamp Authority

RFC 3161 qualified timestamps prove existence of audit records at specific points in time.

Write-Once Storage

Append-only storage backend prevents modification or deletion of historical audit records.

Third-Party Verification

External auditors can independently verify audit log integrity without platform access.

Logged Events

  • • Identity verification attempts and results
  • • Document access and retrieval
  • • Signature generation and validation
  • • Administrative actions and configuration changes
  • • API calls with request/response payloads
  • • Authentication and authorization events
  • • Key rotation and cryptographic operations
  • • Data export and compliance reporting

Retention

Configurable retention periods aligned with regulatory requirements. Default 7-year retention for financial services compliance.

  • • Automatic archival to cold storage
  • • Compliance-ready export formats
  • • Legal hold capabilities
  • • Secure deletion after retention expiry

Designed for Compliance

Architecture built with regulatory compliance as foundational requirement. Continuous adherence to global standards and frameworks.
