Fortinet FortiWeb vs Array ASF Series Web Application Firewall: 2026 Comparison

Fortinet FortiWeb

Mid-market and enterprise teams protecting APIs alongside traditional web applications should start with FortiWeb; its machine learning-driven API discovery and automated policy generation handle the schema chaos that manual WAF rules can't touch. The hybrid deployment model and integrated FortiGate/FortiSandbox ecosystem mean you're not bolting on a standalone tool to your existing Fortinet stack. Skip this if you need SIEM-grade forensics or post-incident recovery workflows; FortiWeb is built for continuous monitoring and threat detection, not investigation depth.

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.
