Sentinel Gateway information
What is Sentinel Gateway?
Sentinel Gateway was built for engineers who need to scale LLM infrastructure without the "latency tax" of traditional Python or Node.js proxies.
While most gateways introduce 50ms–100ms of overhead, Sentinel is a single, compiled Go binary designed for VPC-native deployment. It handles model routing, semantic caching, and PII scrubbing in-memory, ensuring your prompts never leave your secure environment for third-party processing.
Key Technical Advantages:
Performance: Ultra-low ~13ms overhead at P99.
Security: Native PII redaction (Emails, SSNs, CCs) aligned with NIST SP 800-122 standards.
Efficiency: Semantic caching reduces token costs by up to 80% with near-zero latency hits.
Privacy: 100% air-gapped capable; no external SaaS control plane or telemetry required.
Reliability: Automatic provider failover (OpenAI, Anthropic, Gemini, Groq) with zero configuration drift.
Why Go-Native? We moved away from the library-heavy approach to eliminate dependency bloat and Python’s Global Interpreter Lock (GIL) issues. Sentinel is a "drop-in" infrastructure layer that works by simply changing your OpenAI base URL.
