Alibaba Cloud Web Application Firewall (WAF) vs Array ASF Series Web Application Firewall: 2026 Comparison

Alibaba Cloud Web Application Firewall (WAF)

Mid-market and enterprise teams protecting APIs and web applications across hybrid cloud environments should start here; Alibaba Cloud WAF's auto-discovery and full API lifecycle security management handles the asset visibility problem that kills most API protection programs. The platform covers NIST PR.PS and PR.IR thoroughly, meaning you get both attack prevention and resilient architecture management built in. If your infrastructure is entirely outside China or you need WAAP features like client-side protection and advanced JavaScript handling, look elsewhere; this tool's strength is defending the perimeter when you're already embedded in Alibaba's ecosystem.

Array ASF Series Web Application Firewall

Mid-market and enterprise teams defending legacy and cloud applications simultaneously will get the most from Array ASF Series; its multiple deployment modes (bridge, routing, TAP) let you protect workloads across VMware, Hyper-V, and AWS without ripping out your infrastructure. The auto-learning algorithms and behavioral bot detection catch attacks that signature-based WAFs miss, and SSL offloading removes a real performance tax on busy application teams. Skip this if you're a startup looking for a lightweight cloud-native WAF or need deep API schema validation; Array prioritizes layer 7 attack prevention over API-specific threat modeling.
