About SentinelGateway
SentinelGateway functions as an API gateway for AI workloads, routing requests across multiple large language model providers including OpenAI, Anthropic, Google, Groq, LangChain and LlamaIndex. It implements active fallback routing to automatically switch providers when primary services experience rate limits or outages, ensuring continuous availability without user-visible errors. The service includes deterministic semantic caching that returns cached responses in under 50ms for identical prompts without consuming tokens, reducing LLM costs. Zero-trust PII redaction removes sensitive data such as email addresses, social security numbers, credit card details and API keys from prompts before they reach any LLM, protecting against prompt injection attacks. Request tracing provides a centralized dashboard showing every prompt, provider response and latency metric across the entire AI fleet in real time. The platform supports per-provider latency monitoring and dynamic load balancing, enabling teams to identify degraded endpoints and optimize routing decisions automatically.

Frequently asked questions about SentinelGateway
What is SentinelGateway and what does it do?
SentinelGateway is a high-performance API gateway designed for AI workloads, enabling routing across multiple large language model providers such as OpenAI, Anthropic, Google, Groq, LangChain, and LlamaIndex. It provides features like active fallback routing, deterministic semantic caching, zero-trust PII redaction, and real-time request tracing to ensure continuous availability, cost efficiency, and security for AI applications.
Who should use SentinelGateway?
SentinelGateway is suitable for developers, startups, teams, and enterprises building AI-powered products that require reliable, secure, and cost-effective access to multiple LLM providers. It is particularly useful for those needing failover protection, prompt caching, PII scrubbing, or centralized observability across their AI fleet.
How does SentinelGateway handle provider outages or rate limits?
SentinelGateway implements active fallback routing, which automatically switches to alternative providers when primary services experience rate limits or outages. This ensures continuous availability without exposing errors to end users, maintaining seamless operation even during provider disruptions.
Does SentinelGateway support semantic caching, and how does it work?
Yes, SentinelGateway includes deterministic semantic caching that returns cached responses in under 50ms for identical prompts without consuming tokens. This reduces LLM costs by avoiding redundant API calls for repeated queries, improving efficiency and performance for applications with recurring prompts.
How does SentinelGateway protect against prompt injection and data leaks?
SentinelGateway offers zero-trust PII redaction, which automatically removes sensitive data such as email addresses, social security numbers, credit card details, and API keys from prompts before they reach any LLM. This prevents prompt injection attacks and ensures compliance with data security requirements.
What integrations does SentinelGateway support?
SentinelGateway works with every major LLM provider out of the box, including OpenAI, Anthropic, Google, Groq, LangChain, and LlamaIndex. It is compatible with all OpenAI SDK versions and can be integrated with existing AI stacks using minimal code changes, such as replacing the base URL with SentinelGateway's endpoint.
