TL;DR: Automated accessibility tools catch only 30% to 50% of WCAG violations, according to Arxan Technologies, which means scan-based compliance can miss the screen-reader, focus, and workflow failures that determine whether people can actually use a product. Functional validation, not dashboard green lights, is the real accessibility control.
NHIMG editorial — based on content published by Arxan Technologies: The Accessibility Gap: Why Compliance Alone Isn’t Enough
By the numbers:
- Automated accessibility tools can detect only 30% to 50% of WCAG violations, according to Arxan Technologies.
- In the US, disabled households represent nearly $21 billion in spending power, which makes accessibility failures a direct business risk.
Questions worth separating out
Q: How should teams validate accessibility beyond automated scan results?
A: Teams should combine automated scanning with manual testing of critical journeys using the assistive technologies real users rely on.
Q: Why do automated accessibility checks miss so many real problems?
A: Automated checks read code, not context.
Q: What should security and identity teams learn from accessibility failures?
A: They should learn that evidence of compliance is not the same as evidence of function.
Practitioner guidance
- Embed assistive-technology testing into release gates Require manual verification of critical user journeys with tools such as screen readers and keyboard navigation before release approval.
- Measure task success instead of scan pass rates Track whether users can complete high-value journeys such as login, balance checks, checkout, and recovery.
- Review dynamic states as part of QA Test modal dialogs, error alerts, focus order, and state changes in live sessions because those conditions often fail after the page loads.
What's in the full article
Arxan Technologies' full post covers the operational detail this analysis intentionally leaves for the source:
- Specific examples of accessibility failures in screen-reader and keyboard-driven journeys
- The testing workflow it recommends for QA teams working alongside developers
- Practical guidance on using automated tools as a baseline rather than a final gate
- How to measure task success rate instead of relying on scan-only compliance

Accessibility compliance is a governance signal, not an outcome. A green scan can show that code-level rules were satisfied, but it does not prove that a person can complete the task. That distinction matters in identity-heavy journeys such as login, account recovery, and verification, where functional failure creates operational exclusion even without a security incident. The right control model is evidence of use, not evidence of inspection.
A question worth separating out:
Q: How can organisations know if accessibility controls are actually working?
A: Look for task success rate, support ticket trends, and repeated failure points in high-value workflows. If users still abandon key journeys, rely on workarounds, or report keyboard and screen-reader issues, the controls are not effective. Accessibility assurance should prove usability under real operating conditions, not just pass an audit.
