Citrix NetScaler Application Firewall

• Positive Security Model

  Learns normal application behavior automatically and blocks requests that deviate from the learned profile, protecting against zero-day attacks.

• Negative Security Model

  Signature-based protection using regularly updated rule sets to block known attack patterns including OWASP Top 10 threats.

• Bot Management

  Identifies and manages automated traffic using device fingerprinting, CAPTCHA challenges, rate limiting, and reputation-based filtering.

• API Protection

  Schema validation, rate limiting, and content inspection for REST and SOAP APIs with automatic policy generation from API definitions.

• Integrated ADC Platform

  WAF runs on the same appliance handling load balancing, SSL, and content switching, reducing network complexity and latency.

• Centralized Management

  NetScaler Console (formerly MAS) provides centralized policy management, analytics, and configuration across multiple ADC instances.

Invicti

• Proof-Based Scanning

  When a vulnerability is found, Invicti attempts to safely exploit it and provides concrete proof. For SQL injection, it extracts actual data. For file inclusion, it reads a specific file. This eliminates the false positive problem that plagues most security scanners.

• DAST (Dynamic Application Security Testing)

  Tests running web applications by sending crafted HTTP requests and analyzing responses. Finds SQL injection, XSS, CSRF, file inclusion, authentication flaws, and other OWASP Top 10 vulnerabilities in production or staging environments.

• IAST (Interactive Application Security Testing)

  Instruments the application at runtime to provide deeper vulnerability detection. Combines external scanning with internal application visibility. Finds vulnerabilities that pure DAST scanning might miss, such as insecure deserialization or business logic flaws.

• API Security Testing

  Scans REST APIs, GraphQL endpoints, and SOAP services. Imports API definitions (OpenAPI/Swagger, WSDL, GraphQL schemas) and tests all endpoints for vulnerabilities. Critical for modern applications where APIs are the primary attack surface.

• CI/CD Pipeline Integration

  Integrates with Jenkins, Azure DevOps, GitHub Actions, GitLab CI, and other CI/CD platforms. Automatically scans applications as part of the deployment pipeline. Fails builds if critical vulnerabilities are found.

• WAF Rule Export

  Exports discovered vulnerabilities as WAF rules that can be imported into WAF products. Creates targeted virtual patches for specific vulnerabilities found during scanning. Bridges the gap between vulnerability discovery and runtime mitigation.

• Compliance Reporting

  Generates compliance reports mapped to PCI DSS, HIPAA, ISO 27001, and OWASP Top 10 requirements. Useful for demonstrating due diligence during audits and regulatory reviews.

• Single-Page Application Support

  Full support for scanning modern JavaScript applications built with React, Angular, or Vue. Invicti executes JavaScript, interacts with dynamic page elements, and discovers application states that traditional crawlers miss.
