Everything you need to secure your AI

Sentinel combines fast regex matching with deep AI analysis to catch threats other tools miss.

Real-Time Detection

Every prompt is analyzed in milliseconds before it reaches your model. Zero-latency protection powered by a multi-stage detection pipeline.

Four-Tier Detection

A multi-stage pipeline — regex fast-path, embedding similarity, content neutralization, and deep-path AI analysis — scores and handles every threat.

One-Line Integration

Swap your OpenAI base URL and you're protected. Works with any LLM provider that accepts the OpenAI-compatible API.

Attack Analytics

See every threat scored and categorized. Drill into blocked requests, review neutralized prompts, and track attack patterns over time.

API Key Management

Create, rotate, and revoke API keys from your dashboard. Per-tier key limits enforced server-side for safety.

Rate Limiting

Per-tenant rate limits with burst capacity and concurrency controls. Prevent abuse without impacting legitimate users.

Three steps to protection

Integrate Sentinel in minutes, not weeks.

01

Point your traffic to Sentinel

Replace your OpenAI base URL with your Sentinel endpoint. That's it — one line of code.

from openai import OpenAI

client = OpenAI(
    base_url="https://sentinel.ircnet.us/v1/scrub",
    api_key="sk_live_...",  # your Sentinel key
)
02

Sentinel inspects every prompt

Requests flow through a multi-stage pipeline: regex fast-path, embedding similarity, and deep-path AI analysis. Each prompt is scored for threat level.

03

Monitor and respond

Clean prompts pass through transparently. Threats are neutralized or blocked. Review everything in your real-time dashboard.
