Sentinel AI: The Ultimate LLM Security Gateway Against Prompt Injections & Data Leaks

n the digital battlefield, an AI is only as secure as the gateway protecting it. Welcome to the official showcase of Sentinel AI, a robust, pre-model security firewall engineered to protect Large Language Models (LLMs) from sophisticated cyber threats. Developed by Muhammad Bilal Abdullah as the final project for Artificial Intelligence (CSC 262), this system acts as the ultimate Muhafiz (Guardian) between malicious actors and your AI infrastructure.

Modern attackers no longer rely on simple keywords; they use paraphrased evasion, multilingual translations, and context manipulation to jailbreak AI and extract sensitive Personally Identifiable Information (PII). Sentinel AI neutralizes these threats before they ever reach the model.

Shielding the AI Ecosystem:
Built on a high-speed Python/Flask architecture, Sentinel AI abandons legacy rule-only systems in favor of a powerful Hybrid Detection Engine. By merging rapid regex filtering with a Semantic Machine Learning classifier (TF-IDF + Logistic Regression), the gateway understands the intent behind a prompt, not just the words.

Core Tactical Features:

🛡️ Hybrid Threat Detection: Blocks complex, paraphrased prompt injections and jailbreak attempts with 93.4% accuracy.

🌍 Multilingual Defense: Analyzes and neutralizes attacks across English, Urdu, and Korean.

🔐 Regional PII Anonymization: Features a highly customized Microsoft Presidio engine using localized regex to instantly mask Pakistani CNICs and phone numbers.

⚡ Ultra-Low Latency: Processes, analyzes, and sanitizes prompts in under 25 milliseconds, ensuring zero lag for the end user.

🎛️ Live Threat Calibration: A modern, interactive dashboard equipped with dynamic threshold sliders for real-time security adjustments.

This system was stress-tested against a curated dataset of 150 diverse tactical prompts, proving that enterprise-grade security can be achieved without compromising application speed.

The gateway is active. The system is secure. Mission accomplished.
