Version 1.0 research model
A neutral WAF research layer, not a vendor landing page.
WAFWiki is designed around repeatable data fields, official source links, comparison logic, and update notes. The first release intentionally favors verifiable structure over broad but shallow article volume.
Search intent
Pages target long-tail research queries such as reviews, alternatives, versus pages, and deployment guides.
Evidence trail
Official documentation, repositories, product pages, and last-checked dates are visible on profile pages.
Editorial separation
Sponsorship fields are modeled separately from verdicts so commercial links do not decide rankings.
Vendor directory
Start with structured WAF profiles.
Each profile is built from product data, official links, sources, alternatives, and last-checked metadata.
