What VibeGuard Protected Against:
  ✓ Prompt injection attempts (instruction overrides)
  ✓ Jailbreak attacks (DAN, developer mode)
  ✓ Indirect injection (fake system tags)
  ✓ PII exposure (emails, phones, SSN, credit cards)
  ✓ Secret leaks (API keys, credentials)
  
What VibeGuard Allowed:
  ✓ Normal, safe messages
  ✓ Legitimate security questions

Key Features Demonstrated:
  • Confidence scoring (0-100% certainty)
  • PII redaction (replace with [EMAIL], [PHONE], etc.)
  • Secret redaction (replace with [SECRET])
  • Blocked vs allowed decisions
  • Multiple scanner types working together
