SENTINEL API

Real-time prompt hardening and security for your Large Language Models. Protect your AI from injection, jailbreaking, and malicious queries.

The Hardening Funnel

From Chaos to Control

SENTINEL acts as an intelligent security gateway. It intercepts raw user prompts and transforms them through a multi-layer pipeline. Malicious patterns are neutralized, inputs are sanitized, and the final prompt is securely wrapped in a set of instructions that reinforce your AI's safety protocols. This turns unpredictable user input into a predictable, safe instruction for your LLM.

Integration Architecture

Your AI's First Line of Defense

Integrating SENTINEL is simple. Before your application sends a user's prompt to your expensive core LLM (like GPT-4, Claude, or Gemini), it first makes a quick API call to our `/harden` endpoint. SENTINEL processes the prompt in milliseconds and returns a secure, wrapped version. Your application then sends this safe prompt to your LLM, drastically reducing the risk of misuse and exploitation.
