• Managed Rulesets

  Pre-configured rules from Cloudflare and OWASP that are automatically updated to protect against emerging threats.

• Custom Rules

  Create your own firewall rules using Cloudflare's expression language to block, challenge, or allow specific traffic patterns.

• Rate Limiting

  Protect against brute force attacks and API abuse by limiting request rates from specific IPs or patterns.

• Bot Management

  Advanced bot detection and mitigation using machine learning to distinguish good bots from malicious ones.

• API Shield

  Protect API endpoints with schema validation, mutual TLS, and anomaly detection.

• Page Shield

  Monitor and control third-party JavaScript to prevent supply chain attacks and data theft.

• Crowd-Sourced Threat Intelligence

  Network of 200,000+ installations sharing attack signals in real-time. Blocks malicious IPs 7-60 days before other vendors detect them.

• ModSecurity Rule Compatibility

  Load existing ModSecurity SecLang rules directly. Teams migrating from ModSecurity can reuse their rule sets without rewriting.

• Virtual Patching

  Block exploitation attempts at the WAF layer before application patches are deployed. Protect against known CVEs without code changes.

• Advanced Behavior Detection

  Goes beyond single-request analysis. Generates internal events to build complex multi-request scenarios before triggering blocks.

• Proxy Integration

  Native integration with Nginx, Traefik, HAProxy, Apache, and Envoy. No separate appliance needed.

• Kubernetes Ready

  Runs as a sidecar or within ingress controllers. Fits containerized and microservice architectures.

• Console Dashboard

  Web-based management console for monitoring alerts, managing blocklists, and configuring the security engine.

• Community Blocklists

  Free access to crowd-sourced IP blocklists updated in real-time from the CrowdSec network.

• Automatic Policy Generation

  Patented technology automatically creates and optimizes security policies for new applications.

• Positive and Negative Security

  Combines signature-based detection with positive security model for comprehensive protection.

• Bot Manager

  Advanced bot detection using behavioral analysis, device fingerprinting, and CAPTCHA challenges.

• API Protection

  Discover and protect APIs with schema validation, rate limiting, and anomaly detection.

• DDoS Protection

  Integrated network and application layer DDoS mitigation backed by Radware''s global scrubbing network.

• Geo-Fencing

  Block or allow traffic based on geographic location with granular country-level controls.
