Each check maps to a WCAG 2.2 success criterion and its EN 301 549 clause. The European Accessibility Act has applied since 28 June 2025 — its web requirements are commonly assessed against WCAG AA through EN 301 549.
Mapped to the standards.
Every finding carries the criteria it relates to, so the report speaks the language your auditor, legal team and customers expect.
Automated testing detects roughly 30–40% of WCAG issues. A11yProof gives you evidence and monitoring — not a compliance guarantee. Keyboard use, screen-reader experience and meaningful alt text still need a manual review. Standard names are referenced to show methodological alignment only; they do not imply certification, endorsement or affiliation.
