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.

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.
