Security Testing

Cyber attacks cost businesses $10.5 trillion annually by 2025, making security testing mission-critical. AI-powered security testing with MCP servers transforms vulnerability detection from manual audits to intelligent, automated workflows that continuously scan for OWASP Top 10 vulnerabilities, conduct penetration testing, and provide instant remediation guidance.

  • “Perform penetration test on authentication”

AI-Powered Vulnerability Analysis

  • Intelligent threat prioritization
  • Context-aware false positive reduction
  • Automated exploit validation
  • Risk-based remediation guidance

MCP Security Integration

  • Playwright MCP for web security testing
  • GitHub MCP for repository scanning
  • OWASP ZAP MCP for automated scanning
  • Burp Suite MCP for advanced testing

Continuous Security Validation

  • CI/CD pipeline integration
  • Real-time vulnerability monitoring
  • Automated security regression testing
  • Compliance reporting automation
