Features Comparison
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.
open-appsec
-
ML-Based Detection
Pre-trained machine learning engine detects threats based on context and intent, not signatures. No rule tuning required.
-
Automatic Learning
Continuously learns application-specific traffic patterns in production, reducing false positives over time without manual intervention.
-
Native Proxy Integration
Runs as a module inside NGINX, Kong, or Envoy rather than as a separate proxy, eliminating additional network hops and latency.
-
Kubernetes Ingress
Functions as a Kubernetes Ingress Controller with built-in WAF, providing security at the ingress layer without sidecars or service mesh.
-
API Protection
Protects REST APIs against OWASP API Top 10 threats using the same ML engine, with automatic API discovery and schema enforcement.
-
Anti-Bot
Detects and mitigates automated attacks, credential stuffing, and web scraping using behavioral analysis.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
Alibaba Cloud WAF
- You need: Organizations with infrastructure on Alibaba Cloud. Businesses serving audiences in mainland China and Asia-Pacific. E-commerce platforms handling high-traffic events. Enterprises needing Chinese classified protection (MLPS) compliance. Companies with hybrid cloud architectures spanning Alibaba Cloud and on-premises data centers.
- You're using: Alibaba Cloud (ECS, SLB, ALB, CDN, DCDN), any origin via CNAME, hybrid cloud data centers, third-party clouds via DNS
open-appsec
- You need: Kubernetes environments, teams using NGINX or Kong, organizations wanting hands-off WAF protection, cloud-native applications, DevOps teams that do not want to manage WAF rules
- You want to start with a free tier
- You prefer open-source solutions
- You're using: Docker, Kubernetes, Linux, NGINX, Kong Gateway, Envoy
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
