Netsweeper nFilter vs Array ASF Series Web Application Firewall: 2026 Comparison

Netsweeper nFilter

Enterprise and mid-market security teams managing dispersed workforces need nFilter's on-device filtering that works without VPN, eliminating the latency tax of traditional web gateways while keeping content control enforcement local. The AI-powered URL categorization processes requests at carrier grade with zero added latency, and the platform covers Windows, macOS, Chrome, Android, and iOS from a single pane. Skip this if your priority is blocking sophisticated API attacks rather than controlling web and social media access; nFilter's strength is content governance and compliance monitoring, not API-layer threat detection.

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.
