Alibaba Cloud WAF

• AI-Powered Deep Learning Detection

  Uses Alibaba Cloud-developed rules combined with AI deep learning models and proactive protection rules. Threat intelligence is continuously updated from real attack data across the entire Alibaba Cloud network.

• Automatic Zero-Day Protection

  Detects and defends against new web vulnerabilities within hours of discovery, including zero-day vulnerabilities first exposed by Alibaba Cloud. No manual patching required.

• Bot Management

  AI-powered bot identification using fingerprinting, behavioral analysis, and network-wide intelligence. Handles web bots across websites, HTML5 pages, apps, and mini programs. Multiple response methods including blocking, CAPTCHA, throttling, and spoofing.

• API Security

  Proactively discovers APIs including legacy versions, unauthenticated endpoints, and APIs exposing sensitive data. Detects excessive data exposure and sensitive data leaks automatically.

• Data Leak Prevention

  Detects and prevents leaks of sensitive data including ID numbers, bank card numbers, phone numbers, and custom sensitive terms. Includes web tamper proofing that caches and locks critical page content.

• Hybrid Cloud Deployment

  Deploy WAF protection clusters in your own data centers alongside cloud WAF. Same protection capabilities whether traffic flows through Alibaba Cloud or on-premises infrastructure. Supports multi-cloud and hybrid architectures.

• Account Risk Detection

  Automatically identifies account-based attacks including dictionary attacks, brute-force attempts, credential stuffing, and weak password usage.

• Full Access Logging

  Records and stores complete web access logs. Supports real-time SQL-based querying, analysis, and custom alerting through integration with Alibaba Cloud Log Service (SLS).

• Network-Wide Threat Intelligence

  Exclusive threat intelligence accumulated from protecting Alibaba Cloud's massive customer base and internal services (Tmall, Taobao, Alipay). Continuously updated from real production attack scenarios.

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.
