Vendor index

Every WAF vendor we cover, grouped by pricing transparency

Fourteen vendors. Six publish a list rate that lets you assemble a real bill. Seven publish nothing and are honestly labelled quote only. StackPath is included as retired because the search query still surfaces.

Last verified June 2026

Each card links to a vendor deep-dive with pricing tiers, source URL, what they are best for, and the hidden cost line items most quote-only vendors do not advertise.
