Array ASF Series Web Application Firewall vs Fortra Managed Web Application Firewall (WAF): 2026 Comparison

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.

Fortra Managed Web Application Firewall (WAF)

SMBs and mid-market teams without dedicated security operations should choose Fortra Managed Web Application Firewall for its 24/7 SOC support with 15-minute false positive response, which means you stop tuning alerts and start blocking attacks instead. The service covers OWASP Top 10 and zero-day virtual patching, and the managed delivery model eliminates the operational burden of running your own WAF infrastructure. Skip this if you need deep API governance beyond automated discovery or have the staff to operate an unmanaged WAF at a lower cost.
