Features Comparison
Fastly Next-Gen WAF (Signal Sciences)
-
SmartParse Technology
Intelligent parsing technology that understands application context to reduce false positives by 90%+.
-
Power Rules
Flexible rule language for creating custom detection and response logic based on any request attribute.
-
API Discovery
Automatic discovery and cataloging of API endpoints with security assessment.
-
DevOps Integration
Native integrations with CI/CD tools, infrastructure as code support, and developer-friendly APIs.
-
Multi-Environment Deployment
Deploy as cloud service, agent, or edge module across diverse infrastructure.
-
Real-Time Dashboards
Live visibility into attacks, decisions, and application health without sampling.
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.
