Multi-Provider AI Gateway

Access 8 AI providers with text generation, speech-to-text, text-to-speech, content moderation, and document analysis. Single unified API with connection pooling.

Hardware-Backed Security

Apple App Attest validates devices at the silicon level. Certificate chain verification with OCSP checking makes spoofing impossible.

Zero-Knowledge Privacy

No names, emails, or phone numbers on our servers. UUID-based analytics means we see patterns, never people. GDPR-compliant by design.

Encryption Everywhere

TLS/SSL encrypted in transit, Fernet symmetric encryption at rest. Your data stays protected and unreadable.

Fail-Closed Architecture

Most systems fail open when things break. We do the opposite. Redis-backed rate limiting rejects on failure. Security never degrades.

Defense in Depth

Six independent security layers. HMAC-SHA256 signatures, replay prevention, rate limiting. Attackers must break through all of them.

Layered Security Architecture

Response Hardening Layer 6
7 security headers on every response including CSP, HSTS, and X-Frame-Options
Session Security Layer 5
Short-lived access tokens with secure refresh rotation
Rate Limiting Layer 4
Per-device, per-user, and per-IP limits backed by Redis
Replay Prevention Layer 3
5-minute timestamp validation window blocks replay attacks
Request Signing Layer 2
HMAC-SHA256 cryptographic signatures verify request integrity
Device Attestation Layer 1
Apple App Attest with 9 validation steps including OCSP certificate checking
Powered by Microsoft Azure
Auto-scaling Containers 99.9% Uptime SLA Real-time Monitoring

Technical Deep Dive

Authentication Stack

• HMAC-SHA256 request signing with timestamp validation

• Short-lived JWT access tokens with secure refresh rotation

• Apple App Attest with OCSP certificate revocation checking

• Constant-time comparison to prevent timing attacks

Data Protection

• Fernet encryption for API credentials (AES-128-CBC + HMAC-SHA256)

• PostgreSQL with SSL/TLS required connections

• Redis with SSL/TLS for session and rate limit data

• Automatic log sanitization (passwords, tokens, keys redacted)

Infrastructure Security

• Non-root container execution (UID 1000)

• Azure Key Vault for secrets management

• Private container registry with vulnerability scanning

• CORS restrictions to approved origins only

Compliance & Privacy

• CSRF protection via Origin/Referer validation

• Content Security Policy enforcement

• HSTS with 1-year max-age in production

• No PII collection—UUID-based user identification only
