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.

Tempesta FW

• Kernel-Level Performance

  Built directly into Linux TCP/IP stack, processing up to 1.8M HTTP requests per second - 3x faster than Nginx or HAProxy.

• Multi-Layer DDoS Protection

  Integrated protection against volumetric and application-layer DDoS attacks with rate limiting, JavaScript challenges, and adaptive QoS.

• HTTP Tables

  Extends Linux iptables/nftables for application-layer filtering, enabling rules that combine IP addresses with HTTP headers and content.

• Intelligent Load Balancing

  Machine learning-powered load balancing with persistent sessions, weighted round-robin, and rendezvous hashing strategies.

• Web Acceleration

  Built-in caching using Tempesta DB, an ultra-fast in-memory database with NUMA-aware distribution and SIMD optimizations.

• High-Performance TLS

  Tempesta TLS is 40-80% faster than Nginx/OpenSSL with 4x lower latency for TLS handshakes.

• Bot Protection (WebShield)

  Open-source automated bot protection via WebShield — detects and blocks DDoS bots, scrapers, shopping bots, and booking bots using TLS and HTTP fingerprint analysis on access logs stored in ClickHouse.

• Volumetric DDoS Protection

  Upcoming open-source volumetric DDoS protection solution, completing a full L3-L7 DDoS and bot mitigation stack when combined with Tempesta FW's application-layer defences and WebShield.

• Native XDP Integration

  Uses Linux XDP (eXpress Data Path) for early packet dropping, enabling efficient mitigation of volumetric attacks.
