CrowdSec Web Application Firewall

• 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.

DataDome

• Multi-Layered AI Detection

  Combines client-side and server-side signal analysis across thousands of AI models to detect bot intent in real time. Processes both browser fingerprinting and behavioral signals for 99.99% detection accuracy.

• Agent Trust Management

  Identifies and classifies AI agent traffic including LLM crawlers, agentic AI, and MCP clients. Set per-agent policies to allow, block, challenge, or monetize AI traffic across all protected endpoints.

• Account Protect

  Prevents account takeover (ATO), credential stuffing, and fake account creation by analyzing login and registration flows for automated behavior. Customers report 99% reduction in ATO fraud.

• L7 DDoS Protection

  Detects and blocks application-layer DDoS attacks that bypass CDN-level protection. Real-time detection with auto-scaling to 200x average traffic in under one minute.

• AI Crawler Monetization

  Grants controlled access to trusted AI crawlers while blocking unauthorized scrapers. Create rules, define partnerships, and manage AI access to turn crawler traffic into a revenue stream.

• MCP Server Protection

  Secures Model Context Protocol (MCP) servers from agentic threats. Real-time detection and automated blocking protects AI infrastructure while allowing trusted agent interactions.

• Real-Time Dashboard

  Award-winning interface providing instant visibility into threat landscape, traffic composition (human vs bot vs AI), actions taken, and automated reporting. Drill into individual threats and sessions.

• Vulnerability Scanner

  Free tool to assess domain defenses and uncover subdomains exposed to malicious bots and untrusted AI agents. Available without purchase at datadome.co.

• DataDome Intel

  Publicly accessible threat intelligence database powered by 5 trillion daily signals. Covers bots, crawlers, AI agents, CAPTCHA solvers, headless browsers, anti-detect tools, and web unblockers.
