Encryption Layers
Multi-layer encryption at every stage of the data lifecycle.
Layer 1: Client-Side Signal data --> encrypted transport --> Base64 Layer 2: Transport Base64 payload --> TLS 1.3 (ECDHE + AES-256-GCM) Layer 3: At-Rest Decrypted signals --> AES-256-GCM --> Encrypted column store Layer 4: Key Management Master key (HSM) --> Data encryption keys (rotated weekly) DEK envelope encryption --> Per-tenant isolation
Technical Specifications
Client EncryptionAES-128-CBC with session key
TransportTLS 1.3 AES-256-GCM
At-RestAES-256-GCM per-column encryption
Key StorageHSM-backed master keys
Key RotationWeekly DEK rotation, annual master rotation
Section 3
Access Control
Role-based access control with principle of least privilege.
Role Hierarchy:
Owner
|-- Admin (manage team, billing, API keys)
|-- Analyst (read dashboards, export data)
|-- Developer (API access, webhook config)
|-- Viewer (read-only dashboard access)
API Key Scoping:
[key] --> scope: [identify, events, signals]
+--> rate limit: 1000 req/min
+--> IP allowlist: [10.0.0.0/8]
+--> expiry: 90 daysTechnical Specifications
AuthenticationAPI keys (bcrypt-hashed) + SSO/SAML
AuthorizationRBAC with 4 built-in roles
API KeysScoped permissions, IP allowlisting
Session ManagementJWT with 15-min expiry, refresh tokens
MFATOTP and WebAuthn supported
Section 4
Audit Trail
Immutable, tamper-evident audit logging for every action.
Every API call and admin action is logged: 2026-03-16 14:22:01 | api.identify | key:ak_***7f2 | 200 | 12ms 2026-03-16 14:22:03 | api.events | key:ak_***7f2 | 200 | 8ms 2026-03-16 14:23:15 | admin.key.create| user:david@ | 201 | -- 2026-03-16 14:25:44 | admin.role.edit | user:sarah@ | 200 | -- Log Properties: - Append-only (immutable) - SHA-256 hash chain (tamper detection) - 365-day retention (configurable) - Exportable via API or CSV
Technical Specifications
StorageAppend-only log with hash chain
Retention365 days default, configurable to 7 years
IntegritySHA-256 chained hashes, tamper detection
ExportAPI, CSV, SIEM integration (Splunk, Datadog)
