Array ASF Series Web Application Firewall vs BunkerWeb: Side-by-Side Comparison (2026)

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.

BunkerWeb

Teams deploying WAF in Kubernetes or container environments should reach for BunkerWeb first; its open-source model means you customize detection rules without vendor lock-in, and the 10K GitHub stars reflect real adoption by practitioners who've actually tested it in production. The free pricing removes the friction of POC approval, letting you validate WAF efficacy before committing budget. Skip it if your compliance mandate requires commercial SLA support or you need managed rule updates from a vendor with dedicated threat research; BunkerWeb puts rule maintenance on you.
