AegisNexus AI

AegisNexus AI is a production-style AI governance and adversarial defense platform designed to secure modern AI systems against prompt injection attacks, unsafe instructions, policy violations, and malicious agent behavior. The project combines a FastAPI backend with a cinematic React frontend to create a live operational command center for AI security monitoring and governance simulation. The backend architecture was built with modular FastAPI services and includes: • Real-time prompt threat analysis • Governance guardrails for prompt inspection • Policy enforcement engine • SQLite persistence and audit logging • Telemetry streaming using WebSockets • Threat scoring and response recommendations • Gemini API integration with fallback heuristic analysis • Attack simulation endpoints for testing AI resilience The frontend was designed as a futuristic AI defense interface featuring: • Interactive adversarial simulation sandbox • Real-time telemetry monitoring • Threat visualization dashboards • Incident containment indicators • Live risk score analysis • Dynamic governance metrics • Responsive cyberpunk-inspired UI with Framer Motion animations Users can enter prompts into the simulator to test how the governance engine reacts to malicious or unsafe instructions. The platform evaluates the prompt, assigns a threat level, calculates a risk score, and recommends actions such as BLOCK, REVIEW, or ALLOW. Example attacks include: • Prompt injection attempts • Instruction override attacks • Credential extraction attempts • Jailbreak prompts • Policy bypass requests AegisNexus AI was created to demonstrate how future AI systems can include transparent governance layers, safety orchestration, and adversarial monitoring before deploying autonomous agents into real-world environments.
