Features Comparison
Imunify360
-
Managed WAF Rules
ModSecurity-based WAF with proprietary rules maintained by Imunify's security team. Automatically updated to cover new WordPress plugin vulnerabilities, CMS exploits, and emerging attack patterns.
-
Proactive Defense
Real-time PHP script behavior analysis that detects and blocks malicious activity during execution. Catches zero-day attacks that signature-based WAFs miss entirely.
-
Virtual Patching
Blocks exploit attempts against known vulnerabilities in WordPress plugins, themes, and CMS software before official patches are released or applied.
-
WebShield
Reverse proxy layer that filters bot traffic and mitigates DDoS attacks using invisible JavaScript challenges instead of traditional CAPTCHAs.
-
Automated Malware Cleanup
Detects and removes malicious code from files automatically, preserving the original file integrity. Includes database scanning for CMS infections.
-
Global Threat Intelligence
Feeds from 57M+ protected domains. An attack blocked on one server instantly protects all other Imunify-protected servers worldwide.
-
WordPress Plugin
Dedicated WordPress plugin providing site-level security dashboard, scan results, proactive defense status, and malware details directly in wp-admin.
-
Compromised Password Reset
Automatically forces password resets when it detects that cPanel or WordPress credentials were used in an attack, breaking reinfection cycles.
F5 WAF for NGINX
-
7,800+ Attack Signatures
F5's comprehensive threat signature database with continuous updates from F5's threat research team. Covers OWASP Top 10, CVE-specific signatures, and application-specific attack patterns.
-
Declarative Security Policies
WAF policies defined in JSON or YAML, designed for version control and CI/CD integration. Security-as-code approach where policies deploy alongside application code through the same pipelines.
-
API Security
Import OpenAPI/Swagger specifications to automatically enforce API contracts. Schema validation, parameter type checking, and rate limiting for REST, GraphQL, and gRPC APIs. Blocks requests that violate the API specification.
-
ML-Powered DoS Protection
Behavioral analytics using machine learning to detect and mitigate Layer 7 denial-of-service attacks. Learns normal traffic patterns and automatically identifies anomalous request rates, slow POST attacks, and resource exhaustion attempts.
-
Bot Protection
Multi-layered bot detection combining signature matching, anomaly detection, and behavioral analysis. Identifies credential stuffing bots, web scrapers, and automated vulnerability scanners.
-
Kubernetes Ingress WAF
Native WAF support in the NGINX Ingress Controller. Attach WAF policies to specific ingress resources for per-service or per-route security. Policies managed through Kubernetes CRDs and annotations.
-
NGINX One Visual Editor
The NGINX One console provides a GUI-based WAF policy editor, replacing the original CLI-only configuration. Security teams can create, modify, and monitor WAF policies through a web interface without writing JSON.
-
Request and Response Inspection
Inspects both incoming requests and outgoing responses. Response inspection catches data leakage, error messages that reveal application internals, and sensitive data exposure.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
