Array ASF Series Web Application Firewall vs Haltdos Web Application Firewall Community Edition: 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.

Haltdos Web Application Firewall Community Edition

Startups and small teams with limited security budgets should use Haltdos Web Application Firewall Community Edition to block OWASP Top 10 attacks without the licensing cost of commercial WAFs. The free tier includes signature-based protection for SQL injection, XSS, and cross-site request forgery, covering the attacks that hit most early-stage applications. Not suitable for organizations needing advanced threat intelligence, behavioral detection, or API-specific protections; this is a baseline defense tool, not a platform for sophisticated threat hunting or compliance-heavy environments.
