Array ASF Series Web Application Firewall vs Sansec Shield: 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.

Sansec Shield

Magento and Adobe Commerce store owners need Sansec Shield because it blocks vulnerabilities at the application layer within minutes of disclosure, not weeks after patches land. The vendor's three-person team maintains validated detection rules that prevent false positives while covering Magento 2.3 and newer, with zero performance overhead from efficient pattern matching. This is not the tool for enterprises requiring WAF coverage across multiple application stacks; Sansec Shield's strength is depth in one platform, not breadth across ten.
