Overview

Aegis Shield is a universal digital protection platform designed to identify, classify, and respond to online threats targeting women and girls. The system monitors connected social media accounts, detects harmful interactions using AI, and triggers structured emergency response workflows to ensure user safety.

Developed in 24 hours for PowerHack 2025 under the theme: "UNiTE to End Digital Violence Against All Women & Girls." Aegis Shield emerged as the winning project, recognized for its innovation, impact, and technical execution.

Problem Statement

Digital violence—including harassment, cyberbullying, hate speech, and direct threats—has become a major safety issue for women and girls. Existing digital safety tools are fragmented, platform-specific, and lack automated emergency response capabilities.

Aegis Shield addresses this by providing a single AI-driven protection layer across multiple social platforms with immediate safety action mechanisms.

• Platform connection health and monitoring dashboard.

2. Intelligent Alert System

• Multi-level threat scoring powered by AI.
• Detailed alert logs with timestamps and platform context.
• Real-time notifications for high and critical threats.
• Exportable incident reports (CSV/PDF) for legal purposes.

3. Safe Circle Emergency Network

• Add trusted emergency contacts.
• Custom alert thresholds per contact.
• Automatic notifications on critical threats.
• One-tap emergency activation for immediate help.
