CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Mid-market and enterprise teams defending APIs and web applications against coordinated attacks will get the most from Imperva Application Security; its bot protection and DDoS mitigation are genuinely difficult to bypass, which matters when attackers are testing your perimeter daily. The platform covers PCI DSS 4.0 compliance and delivers real-time blocking across web, mobile, and API surfaces without requiring you to rebuild your infrastructure. Skip this if you need a unified CNAPP that also handles cloud-native workloads or infrastructure scanning; Imperva stays focused on the application layer where it's strong.
