Features Comparison
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.
Solid Security (formerly iThemes Security)
-
Patchstack Firewall
Virtual patching rules powered by Patchstack that protect against known plugin and theme vulnerabilities automatically.
-
Two-Factor Authentication
Multiple 2FA methods including authenticator apps, email codes, and backup codes for all user roles.
-
Passwordless Login
Login via passkeys and biometrics, eliminating password-based attacks entirely (Pro feature).
-
Site Scanner
Checks for known malware, vulnerabilities in plugins and themes, and blocklist status.
-
File Change Detection
Monitors WordPress core files and alerts when unexpected changes are detected.
-
Security Dashboard
Unified dashboard showing security status, recent events, and actionable recommendations.
-
Trusted Devices
Recognizes trusted devices and restricts admin access from unknown devices (Pro feature).
