Shield

Real-time phishing detection powered by Gemini AI.

Comment 1

Inspiration

Rising sophistication in phishing attacks and the increasing vulnerability of organizations to social engineering led us to create a solution that leverages Google's latest Gemini AI to provide real-time threat detection. Traditional rule-based systems often fail to catch sophisticated attacks, creating a need for AI-powered protection.

What it does

  • Real-time email scanning using Gemini AI for phishing detection
  • Cloud workload monitoring for suspicious activities
  • Gmail integration via Chrome extension and Gmail Add-on
  • Detailed threat analysis with confidence scoring
  • Actionable security recommendations
  • One-click threat blocking and reporting

How we built it

  • Frontend: React + TypeScript for the dashboard
  • Design: Tailwind CSS for responsive design
  • AI Analysis: Google's Gemini AI API for threat analysis
  • Integration: Chrome Extensions API for Gmail integration
  • Gmail Add-on: Google Workspace Add-ons SDK for native Gmail integration
  • State Management: Zustand
  • Notifications: React Hot Toast

Challenges we ran into

  • Implementing real-time email monitoring without impacting performance
  • Balancing accuracy and speed in AI analysis
  • Handling OAuth authentication securely
  • Creating seamless integration with Gmail's interface
  • Managing complex state across the extension and web app

Accomplishments that we're proud of

  • Achieved high accuracy in phishing detection
  • Created an intuitive, user-friendly interface
  • Implemented real-time scanning with minimal latency
  • Successfully integrated with Gmail's ecosystem
  • Built a scalable architecture for future expansion

What we learned

  • Advanced techniques in AI prompt engineering
  • Best practices for Chrome extension development
  • Complex OAuth implementation strategies
  • Gmail API and Google Workspace integration
  • Real-time monitoring optimization

What's next for Shield

  • Machine learning model training with user feedback
  • Support for additional email providers
  • Advanced attachment scanning
  • Enterprise deployment options
  • Mobile app development
  • API access for third-party integrations
  • Enhanced threat intelligence sharing
